TW391883B - Methods for creating consistent large scale blade deflections - Google Patents

Abstract

Methods are disclosed to design resilient hydrofoils (164) which are capable of having substantially similar large scale blade deflections under significantly varying loads. The methods permit the hydrofoil (164) to experience significantly large-scale deflections to a significantly reduced angle of attack under a relatively light load while avoiding excessive degrees of deflection under increased loading conditions. A predetermined compression range on the lee portion of said hydrofoil (164) permits the hydrofoil (164) to deflect to a predetermined reduced angle of attack with significantly low bending resistance. This predetermined compression range is significantly used up during the deflection to the predetermined angle of attack in an amount effective to create a sufficiently large leeward shift in the neutral bending surface with the load bearing portions of the hydrofoil (164) to permit the hydrofoil (164) to experience a significantly large increase in bending resistance as increased loads deflect the hydrofoil (164) beyone the predetermined reduced angle of attack. The shift in the neutral bending surface causes a significant increase in the elongation range required along an attacking portion of the hydrofoil (164) after the predetermined angle of attack is exceed. Methods are also disclosed for designing the hydrofoil (164) so that it has a natural resonant frequency that is sufficiently close the frequency of the reciprocating strokes used to attain propulsion in an amount sufficient to create harmonic wave addition that creates an amplified oscillation in the free end of the reciprocating hydrofoil (164).

Description of the invention (1) Background of the invention The present invention relates to hydrofoils, in particular to a device for generating movement with respect to a fluid medium, and the present invention also relates to swimming assistance devices, in particular 3 to swimmers' feet and kicked by water A device that generates propulsion by action. · 疋 Relevant technical background notes No known technology fins provide the most energy storage during use, a method of storing energy to produce significant improvements in performance, speed and minimum amount of release. ”There is no known fin design that uses proper Or an effective method is to reduce the angle of attack of the blade about the one-way axis enough to reduce the retardation and generate lift with an explicit t-light and heavier kick. Wan Shi teaches highly flexible teaching viewpoints, beliefs, and design principles that are highly flexible and conducive to the creation of South Speed Swimming. This conventional principle teaches high deflection costs because it is believed that its allowable kick energy cost is distorting the blades rather than pushing them to push the swimmer forward. There is a worldwide industry custom among fin designers, manufacturers, and end users that the more blades there are, the less they can generate power and high speed. The industry also believes that the stiffer the blade, the less energy is spent on the deformation of the blade, and the more effectively the fins can produce nobleness, the entire industry is convinced that this is true because there was no effective = law in the past and the ribs are designed to In a way that can produce super high swimming speed, there is a large blade deflection around a cross ^. Known fin design principles also teach blades = 4 The greater the degree of blade deflection around a transverse axis during a reverse kick, the greater the degree of invalid movement generated at the reversal point of each stroke, where the blade is at The large deflection angle of the counter-point self / swipe loosely rotates past the neutral position of the blade and finally reaches page 7. V. Description of the invention (2) Deflection angle. Conventional principles teach that ineffective movements per kick stroke this amount of kick, because kick energy is used against the blade angle instead of pushing the water backwards. Similarly, the knowledge of the foot continued: Big I: teach the deflection and the greater the range of the blade deflection zone, the invalid movement = push: the greater the part consumed in the deflection of the blade and the stroke is used in production = material, the conventional principles teach This height can be damaged ==… degrees of deflection and subject to 2Γ /, but this height deflection blade is not suitable for use and does not work well. It does not need to have a high swimming speed due to the well-known squatting. It is significantly rigid and reduces excessive blades when vigorously kicked. The blades are placed at very large angles of attack. If the surface or leeward surface flows smoothly, a stall state that is unable to produce lift is generated, and also because the blade is maintained at an angle to the blade while the kicking direction occurs in a vertical kicking energy consumes the propulsive force that pushes the water up and down. When it is known that the fins are made with sufficient bending to achieve a lack of backward force that can flex this amount of bending strength with a significant backward blade, so that the propulsive force is subjected to substantial invalid movement of the blade, and hardened to reduce the inefficiency between strokes Deflection of movement, the fins are known to prevent water from flowing around the low-pressure gauge of the blade when in use. This turbulence creates a significant block in the blades. When placed in the direction of a large attack straight in the horizontal position of a significant person, the majority of swimmers will not be able to make the fatigue when pushing the water backwards to create an orientation with sufficient flexibility to push the water around a horizontal axis. It also makes it impossible for the leaves to apply significant water. This lack of flexural strength also causes the blade to flex to too small during a heavy kick.

Description of the invention (3) The design of the fins that can't produce obvious horns is inside the fins, and the fins ba ': k). In addition, being too flexible or too rigid is familiar with the design of fins. This makes swimmers' feet, popular snorkels, low endurance, potential parades often occur suddenly and the water cannot move. That is, the energy accelerates the elimination of air. In addition, the danger to disease has been known in the past. Excessive resistance Difficulty in a dangerous state. Add excessive strain while exceeding a short distance. Therefore, when using water fins with slow and long advance force, a significant slow speed can be achieved. The horizontal axis of the squat can be flexed. This method can reduce the angle of attack of the squat. Sexually suffer from ankle diving and distance and pain so that no consumption is required and scuba stagnation is increased. There is only a small reason to move forward. The design and lift angle of attack-usually allowed to decrease. In addition, it is not allowed to design during the period, the main shortages and the scuba diving in the leg are strong to make the swimmers have legs and make the scuba diving faster and faster. Scuba diving. Underutilization fully reduced the appearance of Xu leaves. Although 'will allow such large deflections to occur during use, significant energy storage will spring back with significant energy (the dilemma encountered by snaps is: poor squat performance. One of the points is excessive blockage. Muscles produce fatigue and spasms. In water sports, this problem severely reduces the ability to swim in the waves. Leg spasms cannot be kicked, which reduces the total diving time of swimmers in spasms that are used to counteract significant block diving. Increased stress significantly increases decompression kicking fins. The rapid acceleration of disengagement will increase the stepping on the joints and legs. This effort is difficult to maintain the efficiency of the traditional scuba diving by using a slow kick combined with a small push to make the blade around a small angle of attack. It is also not used in light and heavy kicking. Bending around a transverse axis to give the blade a certain skill

Description of the invention (4) Degree of flexibility, but it will allow swimmers to push water to kick energy, which will not be effectively returned to a dangerous state. If the blade is due to this factor, it is known that the angle of attack is too small. Because it is not too hard to bend, it cannot bend enough. Therefore it is hard to allow higher use but lacks the main problem because energy ' reduction is used for uncomfortable consumption at high speed without exerting force '. Due to the known rigid materials, in order to prevent them from being too high, they cannot usually be made more mobile without excessive effort. The blade swimmer's feet are produced against strong waves and heavy kicks. The excessive fins are made of sufficient stiffness. Significantly reduces the ability to scratch large water under a light kick, and the efficiency of the known fin speed increases the force of scuba diving at a high speed, and saves the feeling of excessive deflection. In the main technique, the fins are intended to excessively flex, and kick with the swimmer. The blade is flexed for rigidity so that the blade has sufficient bending strength. If the blade is excessively curved, it is deformed 'because of the hydraulic force applied to the blade and moves forward. This problem will cause swimmers to take off ’or rescue other swimmers. Hip curl’ swimmers will have difficulty reaching high speed β because it does not bend under rigid and strong cruising speeds due to heavy and powerful kicks. If bent to a significant excessive deflection. If it is not slower, it means that the main purpose is to maintain the air consumption. It is known that squatting will be used at low speeds to stroke the fins at a lighter weight to reduce the offensive cruise speed and hold the feet. It can hold the swimmers at a slow swimming time and thus generate muscles. Trapped under low speed forces. This is to soothe, the increased hydraulic power in the fatigue of rigid meat is too new. It will be easy to do this when it is heavy—saving 'hard to enough'. A large amount of air eliminates the use of obvious resonance frequencies in the film. The $ figure matches the automatic frequency of load-bearing members such as load-bearing ribs and leaves. No

The use of metal workpieces' is so easy to be damaged due to corrosion and to add unnecessary weight. For variants of this method, see US Patent Nos. 3665535 (1972) and 4934971 (1988) of Picken; US Patent No. 465 75 1 5 of U.C. Years) and 48 69 696 (1 989). Picken U.S. Patent No. 4,934,971 (1988) discloses a squat that uses a blade that rotates around a lateral axis to achieve a reduced angle of attack with each stroke. Because the distance between the swivel pivot and the trailing edge is significantly larger, the trailing edge edge sweeps a considerable distance between strokes before switching to its new position. In this movement, there is only a small amount of kicks from swimmers that are helpful for advancing, resulting in invalid movement. This problem becomes more serious as the attack angle decreases with each stroke. If the apple is allowed to rotate to a small enough angle of attack to prevent the blade from stalling, the large ineffective movement makes the blade very inefficient. This design appeared briefly on the market and received very poor response from the market and the Scuba Diving Lab (ScubaLab), which is the leading Rodale s Scuba Diving magazine

Many kick types perform very poorly, and ./ indicates that the fins report to water users that they are difficult to use when wearing them. Latent kicks are even heavier. This kind of foot squat design; design with other foot jumps. Benefits < 40 * Degrees of heavy leg fatigue and disgusting for the evaluator. The main problem of this method is that when the end of the webbed paddle stroke reaches its limit, the blades are drawn in each: The longitudinal deflection ribs are used to control the blade deflection around the -transverse θ axis. The author did not use an appropriate method to reduce the angle of attack of the blades. ^ The fins are well-known for the use of fins; Xu-The degree to which the transverse axis is bent. The ribs usually extend from the foot bag to the main length of the leaf. Ribs such as the stomach often extend vertically above the upper surface of the leaf and / or the main β, foot, and the margin of the scapula of the blade is reduced. Hooke's law (Hoke, s Uw) states that the amount of strain or buckling is proportional to the stress or load placed on the rib. Therefore, the amount of buckling of the ribs varies in proportion to the load placed on them. A light kick produces the most f-blade deflection, a medium kick produces a medium-blade deflection, and a heavy kick produces the most t-blade kinking. For this reason, the design methods used to design load-bearing ribs in known arts do produce a significant consistent large blade curve from light kick to heavy kick. It is known that the use of longitudinal load-bearing ribs to control the deflection of the blades around a transverse axis has not adequately reduced the angle of attack of the blades enough to reduce the resistance and to lighter and heavier kicks in a significantly consistent manner. The plan produces lift. These ribs are designed to control the bending of the blade about a transverse axis when in use.

From the out-of-shape bend, a vertical deflection is made, and the quasi-intermediate performance is obtained through the technique of obtaining materials. The deflection is not small, and the vertical energy is extremely deformed by the material on the production side. It is used in the fifth and eighth description of the invention. (8) It is more likely to be excessive. Another problem is that the ribs must be surrounded by the source. It contains high-tech water for a light kick. It requires less storage. And deform the straight beam and arrive. Even the paper did collapse. The strength of this system. If you are deforming laterally and have some knowledge, however, there is no similarity that greatly enables storage. You can know that the fins are designed to use effective materials such as raw springback because of their feet or heavy thickness to reduce the desired vertical. And the narrow twist is subject to tension and the material must be moved at either end a small span because of the resistance of the ribs in the track to collapse. In this way, the cross section of the ribs of the leaf art is taught by the example of the art. The amount is minimized. Designed to produce high dynamic springback with good flexibility and memory but lower spring characteristics. Elongation is considered to be the most advanced material for thermoplastic materials such as ethylene-vinyl acetate graphite and glass fiber. These materials provide substantially linear spring flexure characteristics that cause kicks to deflect excessively. In addition, such use results in significant bending. The power to bounce back. The narrow cross-sectional shape makes it very unstable. When the vertical rib is flexed downwards and pressure is generated elsewhere on the lower part of the rib, the lower part of the rib will tend to bow by holding the edge of a piece of paper when a downward bending force is applied to quickly observe the upper bearing force. The strength of the lateral deformation is greater than that of the elastic material used to resist the lateral deformation, and the track will buckle excessively.

Description of the Invention (9) McCarthy's US Patent No. 5,746,631 shows load-bearing ribs with rounded cross-sections, but it does not disclose any method that allows such tracks to store a higher degree of energy or to lightly kick And heavy kick strokes produce substantially consistent blade deflection. Although the description states that other embodiments may allow the longitudinal track to engage the foot pocket around the track-the longitudinal axis rotation allows the track to bend closer to the foot pocket. 'It does not have any proven method to use the long and Compression produces consistent deflections for light and heavy kicks. 1 疋 f U.S. Patent No. 4,689,029 (1987) to Siconteli shows that the flexible longitudinal ribs extend from the foot pocket to a leaf that is separated from the footbag, although Siconteli shows that the ribs have an oval cross-section to prevent Twisting and stretching also indicate that the flexible ribs are made stiff enough not to overrun at heavy kicks. The patent states that the flexible beam is made of flexible plastic and can be added with glass fiber to increase stiffness and strength. Such flexible beams must be stiff enough to prevent the blades from being excessively deflected by the swimmer's heavy kick, otherwise there will be thrust loss ". This paragraph shows that he is convinced that to provide the maximum speed requires more rigid pieces. This paragraph also shows that Sicontelic is convinced that the use of softer and yet malleable materials in the ribs will cause excessive deflection during heavy kicks and is therefore not suitable for situations requiring high swimming speeds. The second figure shows that the range of deflection (丨 7) is quite small and cannot reduce the angle of attack sufficiently to generate proper lift and prevent stall conditions. In this way, Sicomteli does not know the value of large blade deflection. This limited range of deflection shows that the flexible beams he used were only slightly flexible and relatively rigid. Other than providing inadequate deflections, it has not proposed any method to produce such deflections in light and heavy kicks. Xi Kong Taili also explained that the oval cross-sections of these labels close to the foot bag are about 丨 .50000 by 0.664, and for the fifth, the invention description (10) will require more rigid types | Cross section.

月tU 姿t量- 1王 西孔泰力之美國專利第4773885號（^⑽年）為前文 所述西孔泰力之美國專利第4689〇29號（申請序號第 842282號）之部份續接案。美國專利第4689〇29號顯示西 孔泰力仍未揭示對輕踢產生大幅葉片撓曲且同時防止因重 踢而過度撓曲之方法。雖然美國專利贫4773885號說明撓 性樑係由類橡膠熱塑彈性體材料製成，該等撓性樑之目的 係使該等樑能充分f曲使潛水者能跨地而行或穿過大浪。 其未揭示任何方法將此種樑設計為對變異負載產生一致大 幅葉片撓曲。更未提及任何要對輕踢產生大幅葉片撓曲之 意圖。其所羅列具有撓性樑之僅有優點為使潛水者能在攜 帶裝備之同時跨地而行。其未提及任何創造並控制特定葉 片撓曲之方法’亦未提及使能量儲存最佳化之方法。如此 顯示西孔泰力並不知曉以上好處實屬可行，且不知曉任何 創造並最佳化此種好處之方法。此外.西孔泰力在第3段 五、發明說明（11) 第2 0至3 7行中說到樑2具有充分撓性能充分彎曲，使腳 置於鈦1内之穿戴者旎沿海灘以一般方式行走，其腳後跟 在其腳於球形體上向前滾動之時上舉。然而，樑2具有充 分勁度，在游泳時撓性樑2僅彎曲充分量提供葉片4之良好 鰭動，作，依據前述參考申請案第842282號所揭示之原 則。。他說明該等樑必須依據申請序號第842282號（美 國專利第468 902 9號）之原則為剛硬，該原則在第二圖中 僅顯示實質為小範圍之葉片撓曲（17)。美國專利第 4773885號在圖式中並未顯示所要葉片撓曲範圍且特別說 明在游泳期間該等樑依據現今為美國專利第468 9〇29號在 第二圖中所顯示之小範圍撓性作用，西孔泰力確信此為理 想狀態。此範圍太過狹小，因為其未容許葉片達到一充分 縮小攻角以有效產生升力並降低失速狀況。由於他說明 該等樑應具充分勁度以不因重踢而過度撓曲且在第二圖中 僅顯示一小範圍撓曲（丨7 ) ’很明顯西孔泰力確信超過第 二圖中範圍17之撓曲為*過量撓曲次且會導致、推力損 失。他並未揭示進一步之資訊說明何者為他認為之過量 撓曲角。如此顯示西孔泰力並不認為其撓性樑以能讓葉片 經歷顯著大幅撓曲之方式使用。如此亦顯示西孔泰力並不 知曉任何關於大幅葉片撓曲之好處，且不知曉將肋件以自 大幅葉片撓曲產生新好處或意料之外結果之方式設計之方 法。 美國專利第4773885號之另一問題在於軌道之橫截面 形狀產生易於扭絞及變形之可能性。西孔泰力承認該等樑Monthly tU posture t amount-1 King US Patent No. 4,783,885 (^ ⑽) of Western Kong Taili is a continuation of the part of US Patent No. 4689809 (Application Serial No. 842282) of Western Kong Taili mentioned above. U.S. Patent No. 4,689,029 shows that Sicomtel has not yet disclosed a method of producing large blade deflections with light kicks while preventing excessive deflections due to heavy kicks. Although U.S. Patent No. 4,783,885 states that flexible beams are made of rubber-like thermoplastic elastomer materials, the purpose of these flexible beams is to allow the beams to flex sufficiently to allow divers to walk across the ground or through large waves . It does not disclose any method of designing such a beam to produce a uniformly large blade deflection against a variable load. Not to mention any intention to produce a large blade deflection for a light kick. The only advantage of its flexible beams is that it allows divers to cross the ground while carrying equipment. It does not mention any method to create and control the deflection of a particular leaf, nor does it mention a method to optimize energy storage. This shows that Sicomiteli does not know that the above benefits are feasible, and does not know any methods to create and optimize such benefits. In addition, Xi Kong Taili said in paragraph 3 V. Description of the invention (11) Lines 20 to 37 that the beam 2 has sufficient flexibility and is fully bent, so that the wearer who puts his feet inside the titanium 1 lays along the beach in a general way. Walking, his heels are raised as his feet roll forward on the sphere. However, the beam 2 has sufficient stiffness, and the flexible beam 2 only bends enough to provide good fin movement of the blade 4 during swimming, in accordance with the principles disclosed in the aforementioned reference application No. 842282. . He explained that these beams must be rigid according to the principle of application serial number 842282 (US Patent No. 468 902 9), which only shows the blade deflection in a small area in the second figure (17). U.S. Patent No. 4,783,885 does not show the desired range of blade deflection in the drawing and specifically states that the beams during swimming are based on the small range of flexibility shown in U.S. Pat. Xi Kangtaili is convinced that this is the ideal state. This range is too narrow because it does not allow the blades to reach a sufficiently narrow angle of attack to effectively generate lift and reduce stall conditions. As he stated that the beams should be stiff enough not to flex excessively due to heavy kicks and only show a small range of deflections in the second picture (丨 7) 'It is clear that Sicomtel is confident that it exceeds the range 17 in the second picture The deflection is * excessive deflection times and will result in thrust loss. He did not disclose further information about what was considered an excessive deflection angle. This shows that Sicomtel does not consider its flexible beams to be used in a way that allows the blades to experience significant, significant deflections. This also shows that Sicomteli doesn't know anything about the benefits of large blade deflection, and it does not know how to design ribs in a way that produces new benefits or unexpected results from large blade deflection. Another problem with U.S. Patent No. 4,783,885 is the possibility that the cross-sectional shape of the track is easily twisted and deformed. Siconteli acknowledges these beams

Description of the invention (12) When walking on land, the blades tend to deform and twist when they are flexed. If the beams are deformed and twisted under the large deflections generated during walking, they will also be deformed and twisted when the beams are made of an elastomeric material with a sufficient level of flexibility to exhibit large blade deflection during use. twist. The reason these tracks are easily deformed and damaged is that the first stage twisting turns the rectangular cross section into an oblique rhombus with respect to the bending direction. The upper and lower corners of this part of the beam deviate from the center of the placket (the axis that passes through the geometric center of the beam cross section) when bending. These corner pairs bend farther above and below the beam axis than the rectangular cross-section surface and lower surface before twisting. Since the stress is on the neutral plane of the beam (the lapping plane is relative to a horizontal plane of vertical bending, there is no maximum stress at the highest point above and below the bending stress, these inclined corners have the greatest tension ^ compression Strain in the form of force. Since these corners and the maximum strain within them are deviated from the center of the beam axis, a torsional moment is generated to cause the beam to deform prematurely during bending. As the beam is twisted along its length, the bending strength and The torsional moment varies along the length of the beam. This causes the beam to bend unevenly and forces energy to be lost. This is not used to generate propulsion. Although Xikong Taili raised the outer width at the lower end of the beam to reduce the compression caused there. Deformation 'He explained that the place is used to reduce the deformation of the blades stuck in the ground when walking. He did not explain that it is used to produce any benefits when swimming. He did not use the cross-section thickness to create new but not obvious when swimming. Benefits. Because he designed a small range of blade deflections, he did not disclose the use of cross-sectional shapes to make large deflections from light kicks and prevent excessive deflections from heavy kicks. He also did not disclose any use of cross-loading Shape provides no increase in iv disclosed conventional design can allow the blade to achieve substantial deflection provide

The patent is also not disclosed on page 19. The invention description (14) shows a method for generating under mutated load. Although the specification and drawings refer to the formation of springback motion, there is no S-shaped substantially longitudinal sinusoidal waveform in the drawings, nor is it mentioned in the description. Although the blade has a thicker central portion, the thicker portion is significantly too small to allow the use of a substantially soft material with a significantly large elongation and compression ratio, as this flexibility can cause the blade to flex excessively. Therefore, this design must use a stiffer material with a significantly smaller extension and compression range under the load caused by the kick. This type of material provides a natural resonance frequency that is significantly higher than the swimmer's stroke kick frequency. It is not mentioned in this patent that this is expected or necessary. Although the tip area is designed to bend along the central axis of the fin relative to the thicker part, the drawings and the description do not disclose that the 3 along the length of the blade or the length of the more flexible side area of the blade ^ generates a standing wave or Method of inverting sinusoidal oscillating phase Wi US Patent No. 2,423,571 (1944) of Wilen (1944) shows a fin with a reinforcing member along the center axis of the blade, and the thin and highly flexible film extends to the center Any of the reinforcements.

And thus the pushback movement is the best. Since only thin materials are used, the F-curve is minimized. The same delay will cause a large delay

Page 21 About B Day Π A, You know the freediving fins use very long blades, usually 2 to 4 feet long. Although soft rubber tracks are usually used along the outer edges of these fins, these tracks are not load-bearing structures because the main load is placed on a central rigid blade that is usually rigidly bolted to the bottom of the foot pocket. The central rigid blade is a load-bearing structure and is made of a very thin and highly inextensible material such as glass fiber or carbon fiber reinforced resin or thermoplastic material. These materials typically have hardness numbers that far exceed the Shore A durometer and increase to a harder Shore D durometer. The elongation of these materials is limited to less than 3% and the compression is limited to less than 1%, even for the heaviest kicks. To allow bending, these load-bearing structures are only given very small vertical dimensions or thicknesses that allow bending on the transverse axis and do not require significant extension or compression when undergoing such bending. This thin vertical dimension results in a very high height above the neutral bending axis of the blade, so that the bending resistance occurs with a very small lever arm. 'Reducing the blade's effect due to the damping of the surrounding water. In addition,' the combination of the small lever arm can ignore extension and compression. The rate prevents the branch from efficiently storing energy in the leaves. Although such very long and thin free diving blades can be observed to exhibit a sinusoidal waveform during use, the lack of arms and proper elongation and compression ratios prevent such blades from operating effectively. Similarly, long blades are a lot of submersibles: on the fact that families or travel packs are really long and cumbersome. In addition, leg movements in the A range are required to increase oxygen consumption. Driving large-scale squats requires a large amount of pro, femoral, and quadriceps. The problem of light linear blades is that they are light, and the above problems make long, thin, and thin blades thick and the small lever arm produces insufficient kick deflection and excessive kick deflection.

Description of the invention (17) The nature and non-stretchable load blades become bad answers. No know-how. The design of fins teaches how to modify and adjust the blades naturally. There is no known method by which a skilled artisan can flex a strong load-bearing rib. · ≫ The purpose and advantages of the calendar display The present invention proposes a design that can control the blade's winding-transverse axis deflection = method ', which enables this kind of ribs to be equivalent to the rib-knowledge technique. Method 2: Contradictions to the content taught . Except for the results, the actual and known skill of the flexor ... higher when re-kicked ... probably significantly better than any conventional L-high-yielding leaf know-how that teaches a large blade flexing movement and loss of propulsion. Large blade deflections are produced in a way that produces large voids to exclude invalid motions. Second loss: knowledge; anti: Γ is the energy loss that does not produce propulsive force far exceeds all the conventional skills; ::::: = The reversed part of the movement produces the conventional skills. The propulsive force is lost and the propulsive force is used only to reverse the deflection of the blade into the blade and use the reversing part of the paddle to continue to reverse the paddle to produce a large propulsive force and super high speed. 23rd Stomach and Description of the Invention (18) Known art teaches that blades that undergo large deflections under light kicks will experience excessive deflections under heavy kicks. The method of the present invention discloses how to design load-bearing ribs to be able to Produces large blade deflections and prevents excessive deflection under heavy kicks 0 Known techniques teach that load-bearing ribs made of significantly rigid and strong material with low extensibility allow the blades to have effective springback at the end of the kick. The ability of the position, the method of the present invention reveals how to make load-bearing ribs from a significantly soft and deformable material to produce a significantly enhanced springback capability over conventional techniques. The conventional technique teaches that the high deflection of the blade causes the energy consumption to deform the blade f instead of generating a strong reverse force that pushes the water backward to create a propulsive force. The method of the invention f reveals how the energy used to deform the blade to a large deflection It can be effectively stored in the rib material through high ductility and compressibility and then released at the end of the kick to increase energy recovery. Based on the above, several purposes and advantages of the present invention are: a) Proposing a hydrofoil design that significantly reduces flow separation at low pressure surfaces (or backflow surfaces) during use; b) Proposes significantly reducing ankle and leg production Design of fins for fatigue; c) Propose a fin design that significantly reduces the chance of inconvenience or temporary inability of the swimmer due to leg, joint or foot cramps during use to improve safety and enjoyment; d) Propose for beginners Design of flippers that are as easy to use as advanced swimmers; e) propose flippers that do not require significant strength or athlete ability

The stroke can still provide high propulsion and pressure k) South of the ribs, and the ribs have Low tension should be l) The degree of deflection and shrinkage is proposed. Increasing the transverse load surface forces the upper part of the rib to be low enough to be born under the force of the leaves. The water content on the modulus module is significant. The load-bearing ribs have a minimum load-bearing angle. The material produced during the in-out ribs is large, so that the rib force allows the sides of the leaf height extension to form the design angle of attack. Reduced enough The light resistance is a method of generating the elongation and compression of the material in the lift rib in a significantly consistent manner under the bending stress of the rib due to light kicking. It makes the neutral plane above and below the neutral plane Fully vertical due to the blade deflection to a significant reduction in attack angle extension and compression, and this method allows the ribs to effectively allow the blade to flex to a significant small attack angle with a significant rate of compression and high compression rate; A method of producing a consistent large blade for light kicks' which enables the cross-sectional geometry of the ribs

Description of the invention (24) Experience is defined in terms of speed according to this general principle for general reference use. The same speed. You should understand the meaning here. I do n’t want to be limited by such decisions. Similarly, I will follow the theoretical explanation of the method in the following. Although the design and operation of the 2 = 2 invention is lacking, I do not want to be limited by them; I am convinced that these theories are [but I and the right side view of different squat squats, these fins have blades with reduced thickness and / Or load-bearing ribs. The first picture A shows a conventional art fin, which has blades made of a relatively rigid material; the first picture B shows a different conventional art fin, which is applied to the blade with a more flexible material. The picture C shows the same The conventional technique of squatting is applied in the blade with high-exchangeability material. The first heart shows a flipper 'which has a foot pocket_ connected to a blade 102 which has a neutral position 104 when the flipper is at rest. The dashed line shows the light kick blade flexion 1 generated by the swimmer during light kick strokes, the middle kick blade flexion generated by the middle kick stroke 08, and the heavy kick blade flexion 110 generated during the heavy kick stroke. Since the blade 102 is made of a rigid material, the bends 106, ', 108, and 110 are not sufficiently deflected, and the angle of attack cannot be sufficiently reduced to effectively generate lift. It can be seen that the elbow 106, 108, and 110 are generated from the neutral position 104 at a significantly regular and average distance interval. This shows that the degree of blade deflection is proportional to the force or load applied to the blade and is produced in a significantly linear manner. This, combined with the rigid blade material, makes it impossible for the blade to flex its blades during use. The first picture B shows the same conventional skill fins as shown in the first picture A. The difference lies in that the material used for the blade 102 of the first picture B is more elastic than the first picture a. ) Sex. In Fig. 'B, the dashed line shows the deflection of the blade 102 when it leaves the neutral position 104 during use. -The light kick blade deflection 112 is caused by a light kick stroke. One kick blade deflection is caused by a kick stroke. One kick kick deflection 1 16 results from the kick kick. Deflection 11 2, 1 1 4 and 11 6 are evenly spaced and there is no significant linear relationship between deflection and load. Deflection 112, 114, and 116 are all insufficiently deflected. Blades cannot produce good performance at low, medium, and high speeds. The first picture C shows the same conventional skill as shown in the first picture A and the first picture B. The difference is that the first blade 102 uses a highly elastic material. In FIG. C, the dotted line shows the light The light-kick blade deflection 118 'produced by kicking the middle-kick blade deflection 120 produced by the kick, and the heavy-kick blade deflection 122 produced by the heavy-kick blade. Deflection 118 is inadequate deflection, while deflection 122 is excessive deflection (Curve 0, first picture A, first picture, first picture c) shows that the fins of the prior art tend to be insufficiently deflected for light kicks or excessively deflected for heavy kicks. There is no significant consistent large blade deflection between light kicks and heavy kicks. Explanation and operation-second picture first picture A and first picture β show a side view of the fins of the conventional art, which have the ability to bend more The blade close to the foot bag. The second foot is connected to a blade 126, which is shown in the figure in dashed line 128. The light kicks produced by light kicks are shown in the figure. The blade deflection η, and the heavy kick blade deflection 134 produced by heavy kick. The right blade 126 is made with a sufficient elastic capacity.

The fragrant blade 126 is made to have sufficient rigidity so as not to be flexed excessively due to heavy kick, and the vegetable slice 126 cannot be flexed sufficiently when lightly kicked. The second figure B shows a side view of a conventional fin, which has a foot pocket 136 and a blade 138, which has a neutral position 140. In this example of the art, the blade 138 has a curved area 142, which is significantly close to the foot pocket 136. Such bending at the region 142 has previously been achieved by using a stiffener inside the outside of the tab 138 which originates from the free end of the blade 138 and ends at or near the region 142. The curved region 142 'is achieved by reducing the thickness of the blade 138 at or near the curved region 142. All such conventional methods of achieving a curved area 142 do not include a method of achieving a substantial blade deflection for light and heavy kicks. The dashed lines show the light kick blade flex J44, the middle kick blade flex 146, and the heavy kick blade flex 148. If the blade 138 is made to have sufficient flexibility to bend from a neutral position 14 to a deflection 144 due to a light kick, the blade 138 will be excessively deflected to a deflection 146 and 148 under a middle kick and a heavy kick, respectively. Description and Operation-Figures 3 to 7 The third figure shows a perspective view of a prior art flipper. The squat has an upward kicking direction of 15 as seen from this figure. A foot pocket 52 is connected to a blade 154, which has a pair of longitudinal ribs 156 on both edges of the blade 154. When the water pressure acts on the blade downwards, it can be seen that the lower edge of the rib 156 of the domain 1 plant ’is caused by the compression force in this area. This matter is caused by the kicking in the direction 150. The blade 154 was born negative. 5. Description of the invention (27) Compressive stress is applied to the lower part of the rib 156. Out. In this way, the ribs 56 are twisted in a corner sounding shape. Because this will reduce the height of the ribs 5 to 2 moments during kicking, the ribs 156 are significantly reduced in front of the curved area 158 'and the blades 1 5 4 collapse due to water pressure. Moreover, the use of many conventional techniques of fins requires the use of significant rigid materials and vertical ribs to prevent twisting and collapse during use. :: 154 cannot fully flex during use to produce good performance. The second "J intends to use a softer material to increase the deflection of the blades, which will cause the ribs to be left 160 and an arrow showing the cross section. The dashed line shows a neutral position; / lean 54 direction of collapse due to pressure. 5-5 -6-6 ^ ^ ^ ^ The structural stability of the foot bag 152 is too visible in the fifth figure. The rib 156 is twisted. The seventh figure shows the rib; see: the deformation of the member 156 under heavy load and extensibility. Less than Ethyl Acetate, its extensibility f under load is less than 5%, and the range of lightness or dust shrinkage produced by light kicking can be neglected. Description and operation of the small load generated by Fu Huanyu in the light stroke-Figures 8 to 10 Figure 8 shows a side view of a fin using the Taifa Moon method. Fifth, the description of the invention (28) Figure 8 shows A foot pocket 162 is connected to a blade 164, which is kicked in an upward kick direction 166. It can be seen that the blade 164 is deflected due to heavy kicking to the heavy kick blade deflection 168. The dotted line shows that the middle kick is being generated Kick blade deflection 17 °, light kick blade deflection 172, and blade 164 are resting neutral blade positions Set 174. The dotted line above the neutral position 174 is the position generated when the kicking direction 166 is reversed. The deflection 172 is at a significant distance from the neutral position 174, indicating that a large blade deflection is caused by a light kick. The deflection 17o and The distance between 172 is smaller than the distance between flex 172 and neutral position 174. The distance between flex 168 and 170 is between the flex between 170 and 172 and The distance between the deflection 172 and the neutral position 1 74 is smaller than when it is. This shows that the blade 64 experiences a large blade deflection with a highly non-linear load (stress.) To deflection (strain) ratio. Deflection 172 , 170 and 168 are a significant tight group, which is a large distance proportional to the neutral position 1 74. Deflection 72 is at a significantly reduced angle of attack, which generates effective propulsion during light kick strokes. Deflection 17 and 168 are also It is in a sufficient reduction of the angle of attack, which produces effective propulsion during mid kick and heavy kick, respectively, without excessively bending to excessively reduce the angle of attack. &Amp; The method of dominating the non-linear behavior of the blade 164 has not been revealed in the past. Also unknown. This method is also not suitable for fin designers Obviously, many of the world's leading fin designers who have seen prototypes that use the open method have not endorsed this method because of the constraints of confidential agreements. These fin designers do think of blades that are overbending and must be stiffer To avoid invalid movement and provide the wearer with = rod utility. Not only did designers not notice a consistent large blade deflection:

Description of the invention (30) It should be understood here that the analysis disclosed below is mainly used to understand the principles and methods used, and not as a single expression used in the analysis of the method of the present invention. The analysis and methods disclosed below are intended to provide a finned designer with a sufficient understanding so that he can use the method of the present invention in any desired manner. The selection of the reference line described below is to guide the user in the direction of fully understanding the principles of the present invention, and to provide one of many possible ways for analysis, observation and visualization of the procedures used. I do not want to be limited by The analysis provided below. It is expected that the following disclosure will allow those skilled in the art to use a rule-of-thumb design method that does not require higher-order structural analysis, while providing a sufficient basis for structural analysis to allow fin designers to use more sophisticated structural analysis principles to fine-tune higher-order performance as needed . The ninth picture shows a close-up enlarged side view of the same flippers as shown in the eighth picture, which also has deflections 168, 170, and 172 caused by the blade being kicked in the kick direction 166. It can be seen that the blades 164 at deflections 168, 17 and 172 are arc-shaped f-curves. The neutral tangent line 176 is shown by a horizontal dotted line, which is located above the dotted line on the upper surface of the blade 164 at the neutral position 174 and is parallel to each other. The line 176 is a reference line showing the blade angle when the blade 164 rests at the neutral position m. A light kick tangent line 178 is indicated by a dotted line that is tangent to the middle portion of the upper surface of the blade 164 when the blade 164 is in flexure 172. A light kick reduces the angle of attack by 180-a 176-shaped arrow at the tangent. Alas. It is shown that the blade 164 from the neutral position 17 = curve 172 occurred at the middle of the blade 164 from the tangent line Π8 to obtain the Ϊ attack ΪΪ.

Description of the invention (32) The surface of the blade 164 is extended by the tensile stress on the surface of the blade, and the surface under the blade 164 is forced to be compressed due to compressive force. The significant vertical height of Λ a in the radius of curvature must be significantly extended or compressed. When the change is small, the degree of extension and compression will increase significantly. To make-a given material :: [ί ί and / or the degree of compression to make the blade 1 64 f to flex 1 72 when a specific kicking force on the blade 164 load, if not during kicking Fully deflected. Due to the large vertical size of the leaves, the pudding religion has to use a soft and extensible material of the same degree to allow the leaves 164 to flex to 172 due to the full extension and compression of the small load caused by the light kick stroke. Because this soft and south-dull ductile material is very fragile, the method of the present invention allows the blade 164 to have a sufficient cross-sectional height to gain strength through the increased thickness of the blade 164. The large radius of curvature of the blade flexes, and the material within the blade 164 is forced to extend and compress significantly over a wide range. By selecting a material with moderate ductility and compressibility for use in the blade 164 ', where the extension and compression range of the material meets the aforementioned geometric requirements and the load generated during light kick, medium kick and heavy kick strokes, its Can achieve consistent large blade deflection through light, medium and heavy kicks. When done correctly, the resulting fins provide new and unexpected results and significantly increase propulsion. The tenth diagram A ', the tenth diagram B and the tenth diagram c show close-up detailed side views of the same blade 164 in the eighth and ninth diagrams. In the tenth figure A, it can be seen that the blades 64 are bent from a neutral position 174 to a deflection 172. Tangent 178 perpendicular to radius 182

The reference line 2 16 is parallel to the radius 184 to show the extent of the extension and compression produced in the blade 164 at the deflection 172. It can be seen in the figure that the reference line 216 and the upper surface 212 intersect in such a way that the portion of the upper surface 212 existing between the reference line 216 and the radius line 184 has the same length as the neutral surface 210. Similarly, in the figure, it can be seen that the reference line 2 16 and the lower surface 214 intersect in such a way that the portion of the lower surface 2i4 existing between the reference line 2 16 and the radius line 1 84 has the same length as the neutral plane 2 丨 0. Therefore, the 'reference line 216 allows the extent of compression and compression occurring within the radius 184 and 182 within the blade 164 to be identified. An extension region 218 exists in a substantially triangular region between the neutral plane 21, the radius 182, the reference line 216, and the upper surface 212. The extension zone 218 shows the extent of the extensions produced in the material of the blade 164 and the forced extension beyond the volume of material of the section of the blade 164 existing between the radius 184 and 182. It can be seen in the figure that the triangular area shown by the extension area 218 increases from its neutral surface 21 to its upper surface. This shows that the amount of elongation increases as the vertical distance from the neutral plane increases, and reaches a maximum extension range 220 of a light kick, which is indicated by an arrow above the upper surface 212 at the extension area 218. The extension range 220 shows the maximum extension in the blade between radius 182 and 184 when the blade 164 spines to 172

Description of the invention (34) Quantity. Preferably, the material used in the blade 164 is sufficiently ductile enough to extend the lighter tensile stress applied to the blade 164 during the light kick stroke to the range 220. A compression region 22 2 is represented by a neutral region 210, a triangle region between the following table-,,,, and ^ 丄 D 彳 口 radius line 182. It can be seen in the figure that the size of the compression region 222 increases from the neutral surface 210 to the lower surface 214, showing that the degree of compression increases with the distance from the neutral surface and reaches a maximum amount along the lower surface 2 1 4. A kick maximum compression range 224 is indicated by a compression zone 222 and an arrow below the lower surface 214. In this example, the maximum compression range 224 shows that the blade 164 is bent to flex by " light kicking from the neutral position 174! Maximum compression in blades 164 between radius 184 and 182 at 72 o'clock. Preferably, the material used in the blade 164 is sufficiently compressible enough to shrink to a range of 2 2 4 due to the lighter compression load applied by the torque on the blade 164 during the light kick stroke. It should be understood here that the amount of elongation and shrinkage in the material of the blade 164 is absolutely within the extension area 218 and the compression area 222. The area 2 spans the pen H 1R / 1 into e 6 between the radius 182 and 184. [5] The extension and contraction of the full-length distribution of the blades 164. In the example in Fig. 10A, the center of the dithering. This shows the ratio of stress (load) to strain (material extension and compression, which is essentially the same as the amount used in the present invention) of the blade 164 used in this example. In this example, both methods are significantly easier to extend than the f method. Because most materials have different stress-to-strain ratios. ：： 二 ：： The extension and compression of the material. The stretched surface is closer to the contracted surface instead of m, which makes the neutral surface significantly deviate from the vicinity of the center of a piece 164. Knowing

These materials do not shrink significantly under the load generated by the kick, making the neutral bending axis too close to the compression side of the blade. When examining the tenth figure A, such a non-shrinkable material may cause the neutral plane 2 i 〇 to be generated along the lower surface 21 4 or at an insignificant distance above the lower surface. This will cause the lower part of the intersection of the reference line 216 and the lower surface 214 to be shifted to the left, making it meet again with the neutral plane 21 0 (at this time, it will exist along the lower surface 2 14) and the radius line 丨 82. Since the reference line 21 6 will remain aligned with the radius line 184 when shifted to the left, the extension area 21 8 will increase significantly. This will increase the length of the maximum extension range 220 and the volume of the forced extension material. This is not what I want ’because the pulling force applied by the twisting moment of the light kick will be insufficient = long to the new range. Instead, you can use one of the following: Applying the twisting moment of the light kick stroke to the material of the minor offender range of the cymbal 164. Preferably, the material used in the blade 164 is capable of generating a large enough contraction range under load to allow centering; the surface is stored at a significant distance above the lower surface 214, because the blade 164 is less bent to flex 172 This will reduce the load required for effective phase deflection 172 during kicking, and thus allow the tenth at the light angle 192 to ^ = the blade 164 praises from the neutral position 174 to the deflection no.

Description of the invention (36) becomes significantly smaller, and becomes smaller when the blade 1 64 approaches the deflection 170 shown in FIG. 10B. In the tenth picture B, the maximum compression range 226 of a middle kick is substantially the same as the compression range 2 24 shown in the tenth picture A, thereby showing the compression force generated by the material in the middle kick of the blade 164 in the tenth picture B Lower resistance to further contraction. In the tenth figure B, this compression resistance causes the neutral bending axis 210 to shift downward, so that the distance between the neutral bending axis 210 and the lower surface 214 is significantly smaller than the distance between the neutral bending axis 210 and the upper surface 212. distance. In the tenth figure b, the extension area 218 is larger than in the tenth figure A 'because the neutral bending axis 21 has shifted closer to the lower surface 214. Since the degree of strain or deformation of the material in the form of extension or compression increases with the distance from the neutral plane, the downward displacement of the neutral bending axis 21o increases the distance between the neutral bending axis 210 and the upper surface 212. An arrow above the extension area 218 shows a maximum extension range of a kick 228, which represents the maximum amount of extension of the blade 164 material when the kick 164 is bent to a flexure of 170. The long range 22 8 is significantly larger than the extended range 22Q shown in the tenth figure A. Such a significant increase in the bending strength of the blade 164 'because the material inside the blade 164 must undergo a significant increase in length along the upper surface 212 to allow the blade 164 to bend from the unflexed 172 shown in FIG. 〇. The tenth rule 192 is only slightly larger than the angle 18 ° shown in the tenth figure A. However, the tenth figure 6 extends the range 2 to 28 points. It is required to show that the blade 164 must be bent from the deflection 172 of the tenth figure A. Before the deflection 17 of the tenth figure B, a significant increase in material was applied to the blade 164. To extend the distance to this significant increase, the distance not only required a significant comparison, but also to increase the increase in the blade due to the neutral bending and the above table. Leverage effect. In addition, the extension area 218 in the tenth figure B

This forced increase in the volume of the material further increases the bending strength when an increased load is applied to the blade 164. This method of controlling large blade deflection allows a predetermined angle of attack to be selected during the light kick stroke, and then select the cross-sectional size of the blade i 64 and a material with sufficient elongation and compression properties, which will meet or approximate the pre-tapping attack. The maximum compression requirement of the angle 'and the increase in the load applied to the blade 164 causes the neutral plane 21 0 to shift significantly closer to the compression side of the blade 丨 6 4 to experience an increase in bending strength. This allows the blades 164 to bend to a significantly reduced angle of attack ' under light loads and does not flex excessively under heavy kicks used to achieve high speeds. The tenth figure C shows that the blade 164 is bent to the near side of the deflection 168 due to heavy kicking (view. It can be seen that the radius lines 204 and 208 are shorter than the radius lines 194 and 198 shown in the tenth figure b. In tenth figure C In the figure, one of the arrows located below the lower surface 214 and close to the radius line 20 04 represents the maximum compression range of the heavy kick 23. It can be seen that the compression range 230 is significantly smaller than the compression range 226 shown in the tenth figure B. This is because along the lower surface The material of 2 1 4 experienced significant resistance to compression under the compressive stress of the torsional moment applied to the blade during heavy kicking. 6 This caused the neutral curved sleeve 210 to move further downward and further away from the upper surface 214. Surface 212. In the tenth figure C, the 'neutral bending axis 210 is significantly closer to the lower surface 214 than that shown in the tenth figure b. This makes the extension 218 shown in the tenth figure C significantly larger than the tenth figure B. In the tenth figure In FIG. C, an arrow above the extension area 218 represents the maximum extension range of the heavy kick 232 ', which is significantly larger than the extension range 228 shown in the tenth figure b, although the angle 02 of the tenth figure C is only slightly larger than the angle of the tenth figure b丨 92. In the tenth figure (: 'the volume of the material shown in the extension area 218' must be extended Degrees, and the

Description of the invention (38) Surface 2 1 2 and neutral bending axis? The comparison shows a significant increase. In this way, when the load arm and the increased load shown in Figures A and B are generated, the second 164 bears a higher swimming speed and at the same time, it increases the resistance and increases the large index. As many ginseng 164-once reached one can produce gold highly effective two with variable strength can be designed to be added on the blade. When the 4-blade U4 selects a predetermined angle of advance force, it will significantly increase the weight and increase the load. When the load is increased, the stress will be generated. When the ice skater switches from light kick to medium or compressed range materials, the resistance will increase exponentially. It can be noticed that the increase in the strength of the crossbow can be more noticeable. And reach the angle quickly and effectively during kicking in use. This means that at the same time, the significant maintainer can significantly improve the range during light kicks. ^ = The category takes a big step forward, because swimming at the same time during heavy kicks = = changes and increases comfort and efficiency, λ ^ m Ύ ^ Fill the knife speed without excessive deflection of the blade. The angle then selects any desired attack by the invention mγ m T-the method here maintains significantly during use. Below ", 2 are examples of blade deflection arrangements that are sufficient for design use. Twelfth 8 = Kick should be at least 10 degrees, and reach an excellent result when the angle 180 is between 15 and 20 degrees. Tune At the same time, the tenth picture & clear needs, the angle 0 must be about 20 degrees, the angle 192 must be 20 to 30 degrees, and the tenth figure C is 30 ° degrees. A light kick can be 20 to Jialai 咣: = wide. The angle 202 shown is about 45 degrees when re-kicked. Table tenth says that the angle 180 of the tenth picture A is significant at the same time when the light kick is significant = picture C The displayed angle should be less than 50 ° during high speed. The program can include: selecting the specific blade deflection required during light kicking. 5. Description of the invention (39) degrees and the specific maximum deflection required during heavy kicking, combined with the blade geometry. And have the above restrictions on elastomeric materials that are used to violate specific low and comfortable cruising speeds in light kicks that create specific bending stresses within the blade material that result in significantly high extensions and / or compressions. Light to medium kick Under the bending stress generated during the planning period, the preferred extension range is about 5% to 10% or more. The compression range is at least 2% or more. An extended range of about 10% to 20% or more during light to medium kicks and a compression range of about 5% to 丨 0% or more can result in improved performance. Then The above significant extension and compression range is combined with the cross-sectional geometry of the blade 164 to produce a significantly lower bending strength when the blade 164 = light kick from the neutral position 174 f to a deflection of 1 to 2 and the blade 164 As the middle kick and heavy kick approached and / or flexed (the flexing of the neutral surface 210 toward the blade 164 when flexing to 170 and 168), a significant deviation was achieved in order to effectively generate large bending resistance in the blade 164 It is very important that the compression of the conventional technology during the swimming of the rigid material is greatly extended. The reason for the known technical load range of Fan Ruozai's reconstruction range is very important in the reconstruction of the negative load of the largest negative load. The heavy component will not be in. Because of the load, because the load has the component to force the component around a vertical cross in the light kick, you need to increase the weight of the component to extend the negligible pressure surface in the lateral direction of the light kick heavy component. Axial hip curve section size, The neutral plane that produces large deflections between blades is not limited as a load-bearing component, and is more limited to about 5%, and it has a range of shrinkage or contraction. During this period, too close to the load reconstruction surface must be extended significantly to a significantly reduced angle of attack Under the maximum load, the deflection is extended by 5%. This is why the small vertical cross section is often used to approach the compression surface of the component.

As a result, the blades are significantly deflected. 1 It is necessary to have Hook's law when kicking, which states that the stress (load) and / or compression of a material is always proportional. Known skill load strain (the extension gauge is not understood and developed-an effective method to make the blade n and the ribs and the weight of the heavy kick to undergo the blade scratch "attack η; kick, the high between the kicks) Linear relationship. Although the tapered blades t ^ load the linear behavior on the sheet, this non-linear behavior is only visible when some non-forces are generated, so it is clearly beyond swimming. The kicking of heavy kicks is not enough to flex the blades. This is because Xi :: dagger kick = vertical axis of the heavy axis = apparent = long bending stress versus long bending strain relationship (long elongation and / or compression) in the laminae. This method allows the deformation in the material of the load-bearing component when it changes. The ## women's volleyball team undergoes a significant orientation when the blade reaches a desired angle of attack, so that the new orientation of the stress existing in the load-bearing component is subject to a given load. There is a proportional relationship between the degree of strain (elongation and / or compression) of the material that produces the significant change and the degree of bending of the load bearing member. In the tenth figure A, tenth figure b and tenth figure C, the blade 164 is bent from the position 174 to the torsion Tunes 172, 170 and 168 'neutral surface 21 0 The downward direction of the lower surface 214 (the compression surface) produces a corresponding offset. Page 46 of the fifth, the description of the invention (41) The degree and ratio of the deviation of the sexual axis toward the lower surface 214 depends essentially on the vertical height of the blade 164 and the ratio of stress to strain ( Commonly referred to as the modulus of elasticity) and the compression and extension of the material in the blade 1 64 during torsional moments during light kicks, medium kicks and heavy kicks. Therefore, a neutral axis is created by combining the vertical height of the blades 164 and the elastic characteristics of a given material Desirable shift of 21 ° position. The shift of the neutral surface 21 ° toward the lower surface 214 (compressed surface) creates the need for the upper surface 212 (tensioned surface) to increase the deflection of a given blade further proportionally. The blade 164 material and vertical dimensions that create this method by an appropriate choice and also meet the new elongation of the blade 164 from flexing 172 to flex 170 and flexing 170 to flex 168 along the upper surface 212 increase the demand, The blade 164 will experience a large increase in flexural strength 'because the load exerted by the material in the blade 164 on these ridges reaches or approaches the elastic limit of its elongation and compression. If the blade 164 is at the flexure 172 If the mass reaches the elastic limit of the amount of extension and compression, even if the kicking force is increased far more than the heavy kick required for high speed, the leaf 164 will not obviously bend more than the deflection 172. The method and relationship of dagger is not approved, know or The application of more extensible materials in the load-bearing components of the conventional arts will result in excessive deflection of the Chinese film due to middle kicks and / or heavy kicks. The size of the vertical cross-section of this series is inscribed as The load is reconfigured to distribute kicking force. ^ The theory of knowing skill determines that the load = the ribs use high ductility or 2 pieces of soft cymbals and excessive deflection. Rigid materials are an effective way to solve this problem. Xi: Alternative use is approved to use extremely soft materials to provide load-bearing members, vertical

Description of the invention (42) In order to produce a blade that obviously meets the requirements of soft materials to achieve the desired angle of attack ^ The extension of the compression range and the compression requirements. 'When the desired angle of attack, the material can effectively produce an anti-strength change sheet called "—the advantage is the ability to significantly reduce J Λ / in the leaves. When the blade ^ 4 material is deflected :: while reducing the angle of attack, it is extended and; = Inside the curved material. The law of physics states that the force of the 164 body of Zang Chongguan is multiplied by the moving distance of the object. If the distance applied to the object is m, the object moves only a short distance: apply to-the object and apply the same force. Make a small amount of work on an object. If the body is used to increase the work. Because the body moves a large distance, the object will be added to the object. The work is equal to the energy. The work of moving the object 4 is equal to bit 2 = running displacement caused by the characteristic displacement resistance force + energy loaded into the spring in small form. The applied method makes the potential energy of the load m in the blade 164 larger. Because of the formula of the present invention Prolonged and compressed materials under significant bending stress produce significant storage in the material: Big! The method allows the energy in the blade member material to be reconstituted during the deflection period to be significantly greater than the energy used in the method of the invention. The release of Fang Fang, thus leading to the advance of the universe. Multi-energy is stored and then returned) The most significant change is more effective. To make energy return (energ m.

V. INTRODUCTION (43). First, because the method of the present invention allows a significant high vertical chirp to be produced for the blade 164. Extending the compression range, the stress stored in the blade 164 extension and compression material is significantly more than the distance from the neutral surface, and a large force arm is generated in the springback action of the blade m to increase the bar. The increased effectiveness pushes the water backwards. Increased energy storage and release combined with the reversal point of each kick cycle produces a rebound force that produces far more than the sun and the moon of any conventional skill _ Dajianfeng The burst push shows that the load-carrying members and ribs of the art squat have been extended under the bending stress, and a significant amount of work has been done on the blade material. = Work = Yuneng's pair-the work done by the object is equal to the consumption The object ; Work time = long and compressed form of spring-like displacement resistance object Jin Er | # work is proportional to the energy stored in the blade material. Because of the significant small work generated in the material during the light kick, s is here The energy stored in the material of the ribs and the blade is significant A 丨: The blade is deformed by light kicking. The production of the load-carrying component is equal to the pressure of the load-bearing component and the component that fall into sleep It is small. Because it is small, it is spring-neutral at the end of the stroke.] The energy stored in the material K is expressed as a displacement 'and then moved and contracted at the same distance: page 49 5. Description of the invention (44) The return force is small The amount of distance applied, the effect of acting on water at its neutral position, the energy returned by the blade in the known technique-the energy of the object, which has bounced back to the form of self-learning, and the effect on the q is significantly smaller. In addition to increasing the energy storage, the method of the present invention that transfers the iris film to water ^ increases the material in the blade 164 to release the stored energy at the end of the kick stroke and stores the energy into the energy step by a significant amount // when it returns to the neutral position 174 significantly Increasing the amount of kick with the arm makes the blade 164 rate and efficiency. In the tenth heart, the tenth @ β 尾;: a significant amount of the power of return movement 218 and the contraction zone 222: Sinoma: Long zone Sexual plane 21 0 — at a significant large vertical distance. The position of the shrinking material in the middle piece 164 produced a significant increase in the efficiency of the crossbar. == Is the shrinkage force on the leaf more effective in increasing the propulsion SV back? :. Fast water ... The combination of the method of the present invention, which has significantly soft and stretchable load-bearing members and prevents them from being flexed due to heavy kicks, with increased energy storage, has a springback effect that far exceeds that of technical load-bearing members. Unprecedented promotion. This is an unexpected result because the soft material is considered too fragile to resist excessive deflection. ◎ The increase in springback f is unexpected because the use of highly flexible materials for load-bearing members to which the method of the present invention is not applied can easily cause excessive flexing. It is not flexible enough to produce a bending moment large enough to cause significant springback. Without sufficient vertical height, such soft load-bearing members do not have sufficient torque and the effect of acting on the material in the form of extension and compression to establish an appropriate increase in energy, or the lack of a sufficient supply of power can only be effective in moving the blades with a large amount of water. Power arm. As the know-how does not recognize the method of the present invention, the use of load-bearing components of the know-how has significant advantages.

Description of the invention (45) Loads generated by significantly rigid materials with low vertical height and volume. With this reduction, the rigid material can return to the end of the kick due to swimming to generate the energy and arms in the material. Because the water has a significant mass, U = the force that relies on energy \ The low energy of the load-bearing components of the know-how: = J = The water is accelerated backwards during the return movement to generate a sufficient propulsive force. The load-bearing member has a large hardness for the material that generates large shrinkage energy. It is preferable to use the Xiao Zhao A hardness of the elastic Zhao material applying the method of the present invention to be less than 80. Indication = degree (dUrometer) ^ Indication The smaller the hardness, the greater the compressibility and ductility. The method of the present invention allows superior performance to be achieved with a significantly lower gauge hardness. The Shore A hardness is about 40 to 85, indicating excellent results. If the Shore A hardness of the materials used is 70 to 85, these materials should have a significant south modulus of elasticity sufficient to produce the desired offset in the neutral curved plane of the load-bearing member for elongation and compression to create a significant consistent large deflection β The blade 164 may require a smaller vertical height when using a larger gauge hardness material, and a higher vertical height may be used when the gauge hardness is smaller. Since the larger vertical height provides greater leverage during the bounce motion of the blade and also allows storage to release more energy, it is preferred for the blade 164 to use a smaller gauge hardness and a higher vertical two degrees.

Description of the invention on page 51 (46)-Species = natural long-wavelength, A-amplitude and low-frequency natural resonance frequencies, "the media have the same mass, thereby generating unprecedented propulsion with the minimum input energy. Figures 11 to 11 The eleventh figure G shows that when the kick is reversed, a significant large and low frequency s-shaped sine wave from the foot bag 162 travels down the length of the leaf core 4 to a free end 240. The S-shaped display blade shown by this wave 164 synchronously provides two reverse oscillation phases, one part of the blade 164 moves upward and the other part moves downward. This is because the blade 164 is designed to resonate at a substantially low natural frequency, which starts from the movement and the foot of the person The kick direction during the Shaw cycle is reversed and amplified. This low-frequency wave propagation is made possible by using a substantially soft and malleable material in combination with a vertical dimension, which can significantly reduce the kick cycle frequency of swimmers. Low-frequency harmonic resonance, the vertical dimension is consistent with the compression range in a way that prevents excessive deflection and produces significant large energy storage. Figure 11A shows the same flippers as Figures 8-10. The flippers have an upward kicking direction 23 6. Place the blade 164 in a flexed position below the neutral position 174. It can be seen that a node 238 near the foot pocket 162 of the blade 164 is bent, and this node is shown by a dot. Node 238 is the blade丨 64 is a reference point, which shows where the opposite rotation occurs during the oscillating cycle of the blade 164. The blade 164 has a free end 240 at the opposite end of the foot pocket 162. It can be seen that the blade 164 is at the foot The portion near the bag 162 has an upward root movement 242 indicated by an arrow. The portion of the blade 164 near the free end 24 o has an upward free end movement indicated by an arrow 244. Movements 242 and 244 occur in the direction of kicking 236 Same direction.

Above the upper surface 21 2 there are three sets of divergent arrows between the node 2 38 and the free end 24 o indicating that the material inside the blade 164_ has been extended along the upper surface 212 due to tensile stress. The two sets of convergence arrows below the lower surface 214 show that this part of the blade 64 has contracted due to compressive stress. The amount of elongation and compression is significantly evenly distributed across the length of the blade 164 and the arrows are used to show the response of a given area across the blade 164 within the material of the blade 164 = the blade 164 is obviously affected by the kicking direction 236 of Figure 11a By flexing, the swimmer can reverse the kicking motion to the eleventh kicking direction 246 shown in FIG. 11. In the eleventh figure b ', a longitudinal wave is propagated downward along the length of the blade 164. In the eleventh figure B, the portion of the blade 164 between the node 238 and the foot pocket 162 has a downward root movement 2j8 indicated by an arrow below the lower surface 214. The portion of the blade 164 between the node 238 and the free end 240 has an upward free end movement 250. Movements 248 and 250 in opposite directions show that the blade 164 provides low-frequency waves of different phases along its length. The blade 164 between the node 238 and the foot pocket 162 is convex and curved downward, and at the same time, the portion of the blade 164 between the node 238 and the free end 240 is convex upwards, indicating that a low-frequency sine wave is formed. The divergent arrow moves the material in the display blade 164 in an extended direction and the convergent arrow moves the material in the display blade 164 in a compressed direction. When the kicking direction 236 in FIG. 11 is reversed to the kicking direction 246 in FIG. 11B, the significantly high flexibility of the blade 164 reverses the phase of the kicking cycle, resulting in the oscillation of the blade 164 Phase is reversed. The significant extended compression range of the blade 164 allows for opposite oscillating phases along the length of the blade 64. Because the method of the present invention allows a large blade to be produced without excessive deflection

The converging arrows below the lower surface 214 between the node 2 38 and the free end 24 o show that the material in the part of the blade 164 is compressed along the lower surface 214 and curved in a concave shape. It can be seen in Figure 11 that the concave curvature of the lower surface 214 between the node 238 and the free end 240 / in the eleventh figure B is obviously equal to or greater than that in the eleventh figure A. This is because in the eleventh figure A, the lower surface 214 is substantially in a maximum deflection state with a given kick force, and when the swipe self-kick direction 236 is reversed to the kick direction 246 shown in the second figure B The sudden change in the direction of kicking causes the water above the blade 164 near the free end 240 to exert a downward resistance opposite to the blade (164 moves upward 250 near the free end 240, thereby generating a sudden increase in compressive stress on the lower surface 214. In the first -J-- In figure B, the downward resistance exerted by the water near the free end 240 above the blade 164 combined with the sudden downward movement of the blade 164 near the foot pocket 162 due to the kicking direction 246 at node 238 and The torsional moment across the blade 164 is generated between the free end 240 and the torsional moment, which is significantly greater than the torsional moment generated by the kicking direction 236 between the node 238 and the free end 240 in Fig. A. Because of the lower surface of Fig. 11A 214 is compressed to the extent that the bending strength is significantly increased. When the downward torsional moment between the node 238 and the free end 240 is increased from the first to the eleventh figure, the stress caused by the increased torsional moment is increased. Only a small increase in compression occurs along the lower surface 214. In the eleventh figure B, the blade 164 is prevented from being deformed or excessively bent due to the torque generated by the reversal of the kicking action, so the longitudinal wave effectively propagates down from the foot pocket 162 along the length of the blade 164 to the free end 240. This This is because the neutral plane is significantly shifted within the blade 164 and the blade 164 significantly resists further deflection between the node 2 38 and the free end 240.

In eleventh 圊 c, the fins continue to be kicked in the kicking direction 246 and the visible node 238 is closer to the free end than shown in figure eleven B. In the tenth-fig C, the blade 164 has a clear It can be seen that the s-shaped pattern shows that the two opposite phases of a successfully propagated longitudinal wave have a significant long wavelength and a significant large amplitude. In the eleventh figure C, the portion of the blade 164 between the node 238 and the foot pocket 162. The tenth-figure B has an enlarged downward convex curvature from the downward movement 248. In the eleventh figure c, the downward movement 2 48 exerts a rotating lever on the outer part of the blade 164 between the node 238 and the free end 240 around the node 238. This continuously accelerates the outer portion of the blade 164, so that the upward movement 250 of the blade 164 achieves a significant high speed ', as achieved by a bullwhip. The lever force generated around the node 238 and increasing the upward movement of 25 ° also generates an opposite lever force to the blade 164 portion between the node 238 and the foot pocket 162, which downwardly 248 the blade. This moves upward in ㈣25. In addition, resistance occurs when the leverage across the node 238 towards the foot pocket 162 occurs. This is a good thing because it accelerates the downward movement 248 of the blade 164 and increases the convenience of kicking the squat in the kicking direction 246.

In this way, along the blade 164, the self-set foot H piece Wing = end 240 sends a vibrating pulse downward. Since the method of the present invention allows the blade 164 to effectively resonate at a natural resonance frequency that is approximately similar to the kick cycle frequency (or at least the energy pulse frequency generated during the kick cycle% reversal point), the blade 164 oscillates the pulse The frequency, amplitude and period are obviously determined by the frequency, amplitude and period of the swimmer's feet in the water. In the eleventh figure D, the node 238 is closer to the free end 240 than that shown in the eleventh figure c. This shows that the undulating waveform effectively propagates from the foot pocket 162 toward the free end 240. In the eleventh figure D, the portion of the blade 164 between the node 238 and the foot pocket 162 becomes more significantly deflected by the water pressure applied to the lower surface 214 by the downward kicking direction 246. It should be understood here that the downward movement 248 shows the downward movement of this part of the blade 164 relative to the surrounding water due to the kicking direction 246. It can be seen in the figure that the part of the blade 164 between the foot pocket 162 and the node 2 38 is bent upward relative to the foot pocket 16 2 due to the water pressure applied by the lower surface 2 4 8 along the lower surface 2 1 4. The portion of the blade 164 between the node 238 and the free end 240 undergoes high-speed upward movement due to the jitter of the longitudinal S-shaped sine wave effectively propagating along the blade 164

Description of the invention (51) 2j〇. The speed of the upward movement is again significantly increased due to the combination of the inside of the outer part of the blade 164 and the lever effect of the rotation around the node 2 38. The lever movement is exerted by the downward movement 248 near the foot pocket 162. In this way, the in-phase constructive interference between the energy pulse generated during the swipe reversal point and the blade 164 self-deficient # β frequency is used to significantly increase the speed and power of a high memory leaf, slice / bounce at the end of the stroke And quality performance. f In the eleventh figure E, the 'free end 24' has bounced back when the wave peak in the blade 164 passes the free end 240, and the node 2 38 is formed on the blade 164 due to the rotational movement of the blade 1 near the foot pocket 162. Near the foot pocket 162. (=: The use of the node 238 and its relative position on the blade 164 are used to convey the overall operating principles used instead of absolute. In the use of this: the dynamic range may be obviously static 丨 'end-view use, special design and different : Perturbation pattern opening> and the use of harmonic resonance. F In the eleventh figure E, the free end 24o still has an upward movement of 25o and has already kicked the deflection 252 to -wave-induced deflection 254. The basic deflection 252 is Only the degree of deflection caused by the hydraulic pressure resistance to the blade 164 during a given kicking force: 曲 254 is the combination of the water pressure applied to the blade U4 during a given kicking force plus the chattering near the free end 240 to cause the blade 164 to pass down The unhindered additional deflection increases the degree of deflection. The momentum of the high-speed wave energy brings the deflection to 2 5 2. This causes an additional pair of convergent arrows above the surface 212 to be displayed along the upper surface 2 1 2. This also = generated Extra extension, shown by the #arrow pair below the lower surface 214 in the figure. The extra extension compression generates extra energy in the blade 164. 5. Description of the invention (52) Storage will be larger than without the tenth-Figure B to the eleventh Figure E. Slide 164 vertical S-shape spread The situation of energy contribution. Since the second method of the present invention significantly prevents the blade 164 from being negatively bent due to kicking during swimming, the wave of the tenth-graph E-induced flexion 2 54 is not excessively bent and is significantly too close The basic deflection is 2 5 2. However, the stored energy increases significantly because the blade 2 = the neutral side faces the upper surface 212 (the compression surface in this example). In order to increase the surface tension, the blade deflection increases linearly with the increase and extension. On the contrary, the offset of the two surfaces produces a highly non-linear proportional relationship. The material within the blade 164 is compressed by a large extension. The stored energy is maximized while controlling and preventing excessive blade deflection. Due to the excessive blade deflection, the at-high effective angle of attack generates an effective propulsive force. In addition, it can :: in the blade 164 to produce significantly stronger than without the added hair J The springback effect produced by the time. Because the swimmer's foot is kicking, the skin = vibration is obviously in the natural resonance frequency range of the blade 164, and the energy of kick production = combined with the natural frequency of the blade 164 produces an in-phase constructive wave = increase, making the blade 1 6 4 之 ^ 整 杂 i Ip significantly increased the amplitude of IMIS oscillation of the Chinese film.

Description of the invention (53) The fins continue to kick in the downward direction 24 6 when kicking, they move in the downward free end 256 self-wave induced deflection 254 to the basic kick deflection 252. Since this forward bounce is generated by the additional stored energy obtained by the wave-induced flexion 254, the downward movement 256 of the blade 164 near the free end 240 is significantly faster than the downward movement 248 of the blade 164 near the foot pocket 162. This significantly increases the driving force of the blades 64 to generate the propulsive force, because the energy of the blade 164 springing near the free end 240 shown in the downward movement 25 6 is combined with the energy generated in the downward kicking direction 246. This produces a strong downward blade oscillation, while using the downward kick direction 246 while requiring only minimal input from the feet of the self-swimmer. This increase in the oscillating speed of the blades 164 in the downward movement 256 allows swimmers to apply their feet and legs in the kicking direction 246 to apply less force than required by the non-wave induced flexure 254 to generate additional energy. In the eleventh figure G, the kicking action is reversed to restore the kicking direction 236 and the upward root motion 242 shown in the eleventh figure A. In the first graph G, the node 238 moves closer to the free point 240 than the eleventh graph E and the eleventh graph f. In the eleventh figure G, the portion of the blade 164 between the node 238 and the free end 240 continues to move in a downward motion 256, while the portion of the blade 164 between the node 238 and the foot pocket 1 62 is upward 242 moves. An s-shaped sine wave-shaped longitudinal wave is transmitted from the foot bag 162 to the blade 164 to the free end 240. The upward movement 242 again generates a rotational lever effect around the node 238 to increase the downward movement of the leaf 164 near the free end 240 by 256 speeds. This leverage increases the speed of the movement 2 5 6 near the free end 240 combined with the eleventh figure: the shown wave induces deflection to gain energy to increase the acceleration of the part of the blade 164. This is not obvious from the eleventh kick direction 246 to the eleventh shown in Figure F

Description of the invention (54) ^ ^ ^ v The frequency of the energy pulses generated by the reversal of the kick motion in the upward kick direction 236 shown in your circle G is the same as that shown in Figures 11 to 11 The sine wave frequencies generated along the blades 164 are shown applied in phase. As a result, constructive wave interference significantly synchronizes the kicking energy input with the natural resonance capability of the blade 164, so that energy can be continuously added to a system with high efficiency and low energy loss. Since the kicking action reversed to the kicking direction 236 in the eleventh figure F adds energy and speed to the downward movement 256 of the blade 164 near the free end 240, the portion of the blade 164 will have significant high speed and large momentum. Let's take the deflection below the basic kick curl 214 shown in Figure A ^. This causes the blade 164 to store more energy, and bounces back at the increased energy and speed at which the increased deflection limit is reached when the kicking action is reversed again. Since the kicking energy is continuously added in phase with the natural resonance frequency capability of the blade 164 to achieve high speed with significantly reduced energy. The use of the method of the present invention has such a significant propulsion effect 'that swimmers can significantly reduce kick energy once a certain speed is reached, allowing swimmers to add only enough energy to not continuously input the same kick. This is because the know-how has never used such a special procedure. The secret protocol is used to squat specific performance characteristics. It is continuously recommended that they look at the more rigid materials and exclude them. This is obvious and needs to be kept oscillating in this instruction sheet. In order to reduce the kick energy at low speeds, it is the unexpected result of the swimmer and continuing to accelerate beyond the desired cruising speed. Without directly informing the prototype of the method used by the present invention and the signing foot designer could not think of what caused such external fin design uniformists to reveal by using a significant soft material in the load bearing member: Hidden procedures and methods are not included in the description of the invention (55). 'In order to allow those skilled in the art to fully explore these methods and procedures,' the performance of the swing hydrofoil can be improved to an unprecedented level. The s-shaped sine wave transmitted along the length of the blade 1 64 is transmitted at a relatively fast speed along the length of the blade 1 64, and the person who has not been informed of this procedure will not notice the occurrence of this sine wave. Even if the pulses are generated at a significant low frequency, they are still high enough to be unnoticeable to the naked eye. You can use the stop video analysis method to view the kick cycle and reverse the S-shaped sine wave. The pulse transfer generated by each kick reversal does not focus on causing a sinusoidal pattern and clearly appears as a basic spring II. The gradation of the sinusoidal wave bending part shown in Figures 10A to 11G = Intake occurs with a noticeably fast pass, making the blade! 64 Seems to be just a new tone up and down. This = sequence is unknown to those who have not been told to look for and observe this hidden behavior and that: accidents, 'fruits of the fin-making skills are unknown. In addition, broadcasts can be effectively used in significant ways. The concept of strengthening the internal transmission of the M.Άm ^ swing (or at least the skin or pulse generated during the kick cycle inversion) in the same phase to strengthen the substantial amplitude of the in-phase occurrence is familiar to the foot: this kind of in-phase vibration has not been expected, And not: Deer: Ten people and S is unknown, the load caused by the expected action = due to the use of the knives in the design of the knives, and the know-how: ίΐ a significant rigid material that extends the contraction range; a longer contraction range Soft materials combined with strategic loading: in addition to the advantages of A, the conventional techniques; make this expected; heavy components have a significantly large 'blade' during light kick: 3 materials allow heavy components to be heavy kicked Avoid excessive flexing while avoiding this 第 61 页

Description of the invention (56). If a rigid material is used, the resonance frequency is too large to effectively transmit and provide a large-amplitude low-frequency wave with a sufficiently large wavelength to form and with reverse phase vibration existing along the length of the blade 164. Just as a loose piano wire resonates at a lower frequency and a tight steel piano wire resonates at a higher frequency, a softer material provides a lower frequency and is more rigid, and a material provides a higher frequency. Due to the fact that the fins of conventional techniques intend to use significantly rigid materials in the load-bearing ribs and blades, the natural resonance frequency of the blades is significantly too high to match the kicking frequency of swimmers. When using softer materials, you should understand the intended purpose and benefits and the correct method to produce the desired result. If the vertical dimension of the blade is too small or too large to fully match the extended compression range of the material used in the blade 164, the blade 164 will be over- or under- flexed, respectively. Because the method of the present invention allows avoiding excessive deflection along the blade 164 while also using the strong arm to generate significantly increased deflection storage, the blade 164 can cause a significant large amplitude S-shaped longitudinal sine wave to be transmitted, which effectively resists the surrounding water block effect. Since the method of the present invention provides sufficient low-frequency resonance, can return and leverage, applying a sufficient amount of water to effectively and significantly reduce the resistance of the water 'can effectively propagate into the water to generate a large propulsive force. The method of the present invention allows the swimmer's kicking frequency to be sufficiently approximated to the common frequency of the blade 164 'so that a large amplitude standing wave is generated on the blade 164. From the resonance frequency of the film 164, the kicking frequency is significantly approximated. The swimmer can easily transfer the kicking movements that occur in sequence and strengthen the resonance vibration of the blade 164. In this way, the makinetic energy can be added to the blade 1 64 resonance frequency in phase, and the sum of the standing waves obtained is significantly increased. The swimmer only needs to add enough to the vibration system to overcome the block effect of the surrounding water to maintain the standing wave at the desired amplitude. Such as ^

Description of the invention (57) The blade 1 6 4 can have a significant large oscillation range while the swimmer uses the minimum effort and the minimum leg movement. By changing the kicking amplitude and frequency to generate blades 164, the in-phase enhanced standing waves of various natural resonance frequency harmonics can reach various speeds. To increase the oscillation frequency of the blade 164, swimmers can achieve this by reducing the range of kicks and increasing the frequency of kicks. Since the method of the present invention allows the blades 164 to resonate at frequencies substantially similar to the kicking frequency range when swimmers use a smaller kicking range, the blades 164 will be significantly adjusted to the harmonics of the kicking frequency and amplitude to continue in-phase construction, and sexual interference As a result, the blade i 64 here undergoes a significantly increased oscillating motion on a given kicking energy applied during swimming. This allows swimmers to achieve good results without having to know how the blades work. What all swimmers must know is that using a smaller range of kicks and increasing or decreasing the speed are compared at the same time! Raising or lowering the kick frequency within the swing range is achieved. This makes the foot ball easy to use and does not require understanding of wave theory, nor does it require a deliberate effort to synchronize the kicking cycle with the resonance behavior of the blade. In contrast, the blades are rounded to the stroke cycle of swimmers using significant small kicks. The test showed or experienced any unusual resonance induction procedures, and only noticed that the flippers produced excellent speed with minimal effort and complete relaxation of the leg muscles. Since the blade resonance occurs at significantly lower frequencies and amplitudes of kicking frequency and amplitude with swimmers, the resonance behavior is so faint and smooth: never thought. Since the use of the fins of the method of the present invention requires deliberate effort, and because the active use of these methods occurs in the case of swimmers, the methods and procedures of the present invention are not obvious today. You can only adjust the range of kicks to be substantially smaller and the number of kicks required. • Wide range of comfort, speed and efficiency can be continuously adjusted according to demand.

Invention Description (58) --- Yes, follow this guide to achieve the best performance. Although swimmers noticed a wide range of extraordinary performance characteristics achieved using such subtle variations in kick range and number of kicks, they still did not notice many of them produced by achieving the wide range of sum resonance patterns made possible by the concealment method of the present invention. Good performance variation. Explanation and operation-Figure 12 'Figure 12 shows seven different side views of different continuities such as a to g during a kicking cycle of a conventional fin. The fin has a load-bearing blade using a highly flexible and soft material. When the light kick is performed, a large blade deflection occurs but the method of the present invention is absent, so it exhibits greatly invalid movement, wasted energy and extremely poor propulsion force. The kick cycle shown in the twelfth figure shows that the flippers are generated by the kick and propulsion force. Vertical movement of both forward movements. It can be seen in the figure that the kick cycle has a kick range of 25 8 and a blade swing range of 26, both of which are indicated by horizontal dashed lines. The kick range 258 has a lower kick limit 262 and an upper swing limit 264. The swing range 260 has a lower blade swing limit 266 and an upper blade swing limit 268. In the swipe position a, an arrow next to a foot indicates that the foot moves downward. The arrow under the foot in the middle of a indicates that the blade is completely bent and moves downward with the swimmer's foot due to the negative generated during the light kick stroke. Move to the lower limit 26 2 of the moving range and prepare to reverse its kicking side; J = the piece has been bent to the large blade during the period ★ curved and not used by the present invention. The arrow next to the 'foot' in b indicates that the swimmer has reversed the kick into an upward kick. The arrow below the blade indicates that the blade is moving down and has reached a neutral or undeflected blade position. This is because the weak rebound of the blade produces a slow rebound speed that is substantially equal to the upward movement of the foot during the upward kick. In position c, the foot moves up and the blade moves down to finally reach its fully kicked position of light kicking. It can be seen in the figure that the free ends of the blades in the positions a and b # c actually stay near the lower swing range 266. This is due to the large number of ineffective movements in which the thrust is lost when the blade reverses its deflection angle. Propulsion is extremely extreme because energy is dissipated in Baoqu blades rather than pushing the diver forward. Since Qu U did not use any method to store a large amount of energy, it was used to lose the amount of bending and thus it was impossible to spring back at the end of the kick. :: Yi: Because there is no effective method to develop in the substantially fragile and soft load-bearing members To compensate for this serious problem, Feather 妯 妯 is made of self-loading components in a significantly rigid material: the use of m-fins causes insufficient blade deflection. Tsai Yuexian is limited and the productivity during the light kick. 费 费 费 费; fee: the cover leaves do not produce a significant propulsion piece trapped in these two = ⑴: due to the high flexibility of the leaves and high pull leaves to avoid Use materials. Significant rigidity showing minimal deflection in position d 'because the blade is fully deflected under the load of light kicking. According to the invention description (60) Both the foot and the blade are moved upwards as the blade has stopped deflection low because The blade did not push. Any increase in kick force is lost and excessively bent. The dynamic propulsive force is finally reached and can provide propulsive force to the swimmer. It can reach the upper kick pole positions c and d. This propulsive force is remarkably large flexural strength, and a large deflection in the water phase will produce a small angle of attack. Limit 264 at position d and prepare to reverse the stroke only on. Swim using this property to dive. From time to time, the upward-producing rotary motion is used to move the position from position a to position 1 (at 1 o'clock, the energy consumed during positions c and d is used. Most of the stroke cost is in the reverse blade deflection habit. The design principles of know-how fins teach the use of stiffer materials and minimize the amount of blade deflection generated during each period to reduce ineffective movements. Such as poor energy storage and large leg strains. = Material will still be moving During the period, there was a significant amount of invalid operation. The art course and the diving instructor taught the diving students to: move the range to allow the vertical blade to move after the blade is fully deflected. The thigh muscles produce large movements. This is very inefficient because smaller blade flexion means less water is pushed back and more water is formed. There is a lack of effectiveness in the design of fins. Know the method of the present invention. In the middle, the foot moves downward and the blade rises upward when the kick direction is reversed. The horizontal position indicates that the blade has reached the neutral resting position and the foot is moved downward and the blade is moved upwards at the middle position. Finally reached its light

Description of the invention (61) Fully flexed position under kick load. Position ... The free end of the blade is a small amount of movement, and there is a lot of invalid luck at the beginning of the downward stroke. In position g, both the blade and the foot have moved downward and have reached the lower kick pole 262 and are ready to reverse the stroke direction. The propulsive force is substantially limited and occurs between positions ^ and. At this time, energy consumption is in most of the time of the downward stroke. The large kick range 258 produces large vertical leg movements and generates extreme pushes, as seen by the limited horizontal forward movement of the swimmer's feet. The swing range 260 of the picture is significantly smaller than the kick range 258r. This shows that the total distance of the song is significantly smaller than the distance that the swimmer must move his foot. Turning back: two: and a picture of the know-how of the art of squatting, its original = the distance that the blade bends to make the blade travel a significant distance during use. This is not true because = the invaders flexed the leaves when they floated in the water. They did not show swimming because of the blocking effect of water: relatively vertical movement. JL-^ ^ ^ During the period of use, the blades that are deflected from a neutral resting position will bounce like a high retardation: the neutral blade position will not bounce past this Zhongshan Keyue b blade swing range is greater than- -The swing range reached by the free agitation of the non-curved blade. Because of the conventional techniques, two hearts and two hearts ::: The obvious small amount of energy exerted by the small force arm, the greater the flexibility of squatting, the lower the leaf is. Therefore, the problem of blades of the know-how is that the know-how can make the biggest difference. This rigid foot jump forces the swing distance to drop, and the ice skater uses a substantially large kick range, and on page 67. V. Description of the invention (62) After the blade has fully flexed, overcoming the conventional techniques can reduce the flexible blade. f suffer from muscle fatigue at the same time.

The reason for this may be because the square of the present invention f =-when the supply of load blades or load components and the direction of kicking are reversed, the amplitude or frequency (or period) of the downgoing seismic wave is sufficiently approximated to one of total = frequency harmonics . In this way, a sum of resonance in phase with the seismic wave is generated in the load member, and the amount is sufficient to amplify the amplitude of the shock wave when the shock wave is transmitted along the length of the load member toward the fin rate.

Explanation of the invention (63) The amplitude of the wave is significantly increased. In the kick position a of the thirteenth figure, the large arrow below the swimmer's foot indicates that the foot is moving downward. The downward arrow below the blade shows that part of the blade is moving down. The flippers that have reached the lower kick limit 274 become deflected by the water pressure generated during the light kick. The downward arrow below the free end of the blade shows that the blade begins to move slightly upwards. Because the method of the present invention allows the blade to be flexed to a significantly reduced angle of attack, the energy can be efficiently stored in a significant large volume of high-quality extended compression high-memory material, and since the resistance is established at high speed after the desired large deflection is reached A large number of flexural strengths can be stored in the blade shown in position 3. As mentioned previously, swimmers need only be instructed to use a small kick stroke without having to shoulder-to-shoulder the procedures that occur to allow them to use the squat using the invention. Borrowing speed used in the range of 2 years old and high can dramatically achieve high acceleration and speed. By continuously making the kick as far as possible for the smallest possible kicking range ^ The direction of reversal can reach a super high burst speed. The highest speed can be achieved when the blade has become fully scratched by reversing the kicking movement while allowing swimmers to feel a slight amount of resistance or even reversing the kicking direction before the blades are fully flexed. Swimmers are counter-intuitive, because the principle of knowledge teaches them 2 to build resistance to push water before propulsion can be reached. The reversal portion of this teaching stroke produces ineffective movements in which no push is expended to consume energy. This shows that the results of the present invention are not obvious, new / except, and the basic procedures that make such results possible are also unknown. ^ In position b, the large arrow above the foot indicates that the direction of kicking has been set in a.

Description of the invention (64) ----- In the middle stroke, the direction is reversed. From the foot bag to the free end of the blade along the length of the blade, an energy pulse or shock wave is transmitted. Since the method of the present invention allows the blade to naturally resonate with low-frequency harmonics of this longitudinal shock wave, the amplitude or wavelength is significantly amplified by the resonance quality of the blade. The arrow near the foot pocket above the blade shows that the leaf is moving upwards along with the swimmer's feet. The downward arrow below the free end of the blade shows that this part of the blade is moving down in the direction opposite to the direction of the kick. This is because the large energy stored in the deflected blade shown in position a is released to produce a rebound motion, which is further propelled by large amplitude low frequency waves transmitted down the blade length. Due to the significantly high ductility, compressibility 'memory and non-linear deflection characteristics provided by the method of the present invention, there is a significant time delay between applying a load in the blade and establishing a corresponding anti-f bending moment. This delay is due to the time it takes to compress the material in the blade in a direction orthogonal to the cross section of the blade, and it also results from the time taken for the blade's neutral axis to shift sufficiently toward the blade compression surface to produce a significant increase in bending strength. The time delay between this load and deflection increases towards the free end of the blade. ^ When the blade is deflected after being kicked in the first direction, the first blade is deflected and reversed to the second kick direction causing a reverse blade deflection. 'The reverse blade deflection originated near the foot pocket and traveled towards the free end at a delayed speed. Since the first blade deflection occurs after a significant delay, the second reverse blade deflection can occur near the foot pocket while the first blade deflection still occurs near the free end of the blade. In this way, an S-shaped wave ' Preferably, this time delay is substantially the same as the period of a single stroke (or half of a full kick cycle), or the cycle of the reversal part of each kick, or the shock wave generated when the kick direction is reversed

Invention Description (65) The period is similar. It should be understood here that as long as the pulse period of the wave traveling down the blade is sufficiently in phase with the flipping effect of the flippers, the energy, speed and amplitude of the rebound effect can be significantly smaller than the period of a single kicking action. The resonance frequency spectrum wave of the blade amplified by the blade resonance quality supply is better (but not necessary) to occur in substantially the same phase as the reversed part of the kick ring, so that the springback effect near the free end of the blade has less resonance and resonance than the blade Higher speed, larger amplitude and shorter period. Tian's position b in the thirteenth figure can be seen in the figure. At the same time, reverse blade deflection occurs along the blade length, although the foot movement is reversed at the kick limit 2 74 below the position a, and the free end of the blade in position b Passed the limit 270 and continued to move toward the lower blade swing limit 278. The reason is the addition of in-phase waves. The rebound energy stored in position a is released in position b in the same direction as the kick reverses the direction and is amplified by the low-frequency harmonic supply of the natural resonance frequency of the blade along the longitudinal wave of the blade. This produces a synergistic effect that greatly increases the amplitude, speed, and energy of the blade swing produced by the kick. In position c, the foot has reached the upper kick range 276 and the free end of the blade is approaching the lower blade swing limit 278. The foot is moving upwards, the blades are flexing significantly and the direction of kicking is ready to be reversed. It can be seen in the figure that the time delay of the blade deflection is that the root of the blade near the foot bag moves forward and the free end of the blade still moves downward. The kicking direction has been reversed in position d. The free end of the blade shown in position d has moved a significant distance from the position shown in position c. The distance of the pair of feet moving from position c to position d is a significant proportion. Thus, the free end of the blade in the display position ^ moves at a significantly high speed even when the input energy is minimum.

Move up towards the upper blade swing limit 280. In the picture you can see the leaf ί 2 Zhong Gongsuo: more deflection. This is because the deflection shown in position 3 is reached before 'Z u. The harmonic resonance system in positions b to e states that η Λ significantly extends beyond the kick range 270 to the larger blade swing range a *. In this embodiment, the 'spectrum and the accumulation of co-seismic wave energy can be used to overcome the water blocking effect and the blade resistance coefficient, so that the blade swing range is far beyond that achieved by the conventional art blade. The target is surrounded by 6, and it can be seen that the method of the present invention allows the root of the blade to oscillate in a direction opposite to the free end of the blade. This shows that a standing wave is reached with a node area substantially existing between the two blade sections. The standing wave is essentially in phase with the used, paddling action. This allows swimmers to continuously add energy to the blade oscillations in a manner that strengthens and adds to the standing wave. As we all know, if a standing wave is a harmonic that occurs at the resonance frequency of an object, it is in phase with the oscillation of the standing wave. A small amount of energy input from the object can cause a dramatic increase in the amplitude of the standing wave. This phenomenon is known as a problem that can destroy bridges and other large structures. 'However, it has not been previously known that this phenomenon can be used to increase the efficiency and propulsive force of fin blades and exhaust propeller blades. In addition to providing such a flexible blade harmonic resonance program, the elbow control method of the present invention provides exceptional control of this program. This is because the method of the present invention, which allows large blade buckling to occur during light strokes and at the same time restrict excessive deflection during heavy strokes, allows the blade deflection limit to be set. When the blade approaches the predetermined deflection limit, a significant shift in the position of the 'neutral plane' causes a sharp increase in the bending strength without further movement of the blade. Since this procedure occurs exponentially in a smooth manner,

Description of the invention (67) It means that there will be no snoring, no clicking, or stimulation of the user's perception. An exponential increase in the resistance to strength produces smoothness, similar to the exponential increase in resistance experienced by a person when the bounce reaches the full deflection of the spring pad. Since the present invention provides an effective way to limit the deflection of the blade, the use of harmonic resonance is controlled and the blade is prevented from being excessively deflected by the addition of wave energy. The ability of harmonic resonance to increase the amplitude of the wave is essentially controlled by the blade deflection limit suppression. This allows the user to reverse the direction of kicking as needed. When the oscillating blade reaches the desired blade limit, the wave will bounce off the limit set by the blade's sharp increase in bending strength, causing the wave to turn in other directions. The user can control this by intentionally changing the direction of the kick during use. If the direction of the kick is changed, the blade will move towards the oncoming wave, causing the wave to collide with the blade deflection limit in less time. This also allows the user to add energy to the rebound effect of the wave by increasing the kick speed and strength to add energy to the impact. This increases the wave energy when the wave is reflected in the opposite direction after the impact. The user can again choose to quickly reverse the kick direction immediately after the impact and wave energy reflection, so that the swing limit of the other blade is moved towards the recent reflection, and the oncoming wave is moved for another energy construction impact. The shorter the time interval between kick reversals, the more the number of blade reflections and the greater the oscillation frequency of the blade motion. This procedure results in a standing wave-induced U-loop effect that produces a significant increase in blade speed in water. The longer the time between kick reversals, the lower the blade oscillation frequency and the slower the swimming speed. Because the method of the present invention effectively achieves the blade deflection limit, the user can easily and ignorantly control the complex resonance procedures occurring in the blade and create any desired speed by only changing the range and number of strokes. The blade limit achieved by the method of the invention allows the user to control the resonance program consistently over a wide range of swimming speeds. Since the method of the present invention is so smooth and effective, swimmers

Explanation of the invention (68) It can be kept completely without procedures. The main reason is to let them apply the water acceleration of this invention. The elastic memory material exerts a large specific work when it is flexed during the action. It is a high-memory material in the form of potential energy and the pull in the upper part of the material after compression, which produces an understanding of any benefits. Allowing to increase the storage in the extended material can provide excellent energy and extend the compression for effective storage. The intention is to return to its expansion. If the leaf is extended, the lever effect is complicated. The performance of the hydrofoil blade is said to make the blade back in the long compression. From this, at the same time of rebounding, the effect of pushing the memory material on the material is extended to a significant distance along the blade along the blade, which has a significant effect on the performance of the leaf material. The lower part of the film produces a bar above the surface to increase the display. Range material transport provides power, crowding. Thanks to efficient storage over long distances. Such as degrees. The thirteenth procedure does not require detailed instructions. The designer's above method can significantly improve. The rebound period in water can reach a range to extend the unstressed state during the period when a significant swath of water flexes and the blades flex to a significant effect on the material. After the extension, the blade deflection spring from the bottom will exert a lever effect on the blade moment. The blade after the deflection will be compressed upwards, and the material will act upward torsion moment along this part of the blade rod. The knot of the thrust and pull of Shi Yandu is applied after the prolongation and recovery of the house. The pull and thrust are applied to the leaf blade with a significantly strange recovery force. The force generated by the light kick is applied in a significant amount during the rebound action. The large amplitude vibration of the standing wave shown in the figure at the end of the reaction teaches the details and procedures of the detailed content and to a more effective volume. Two blades bounce back the work of large deflection and the compressed material contracts back. Pull. In this film, the length of the material is added to the high note. After the material has been retracted, the material piece moves. The force of the long and long distance in the display significantly increases the fluctuation of the water. Page 74 V. Explanation of the invention (69) External water acceleration , Because the increase of the propulsion force is applied to the distance of the water. Description and Operation-Figures Fourteen to Twenty-seventh Figures Fourteenth and Fifteenth Figures show a perspective view of the substantially large vertical thickness of the transfin leaves on the flippers. One blade and two blades are attached to the leg 284, the blade 282 is kicked in the kicking direction 286 and is operated in the water. The fifteenth figure shows a cross-sectional view taken from the fourteenth to midline 15-15. It can be seen that the blade 282 has a rectangular cross section. In this embodiment 2 8 2 is a single load carrying member and has a vertical dimension sufficient to achieve any desired cross-sectional shape of the method of the invention. Other cross-sectional shapes include oval, ribbed, ribbed, tile-shaped, cymbal-shaped, slotted, beveled, V = other two faceted, or can be used in conjunction with the method of the present invention. Any jinqi t: shape. In other embodiments, the longitudinal grooves, thickness variations, or ribs can be across the J-ribs of the blade 282 in any desired form: the grooves or thickness variations can be made of a material different from the blade m or can have various shapes Consisting of multiple materials of consistency. Figure 282 shows that the blade 282 has a uniform thickness cross section. This allows the blade 282 to provide a good bending stress distribution with effective spring characteristics. Blades: Yes = In the low frequency spectrum with large amplitude of its natural resonance frequency, vibration C can thus generate a high momentum-to-resistance ratio. Since Zhuhe Gong M2 has t% of the skin that can be maintained with a small amount of energy, large momentum can make the blade mass and the blocking effect produced by the -Λ 82 drag coefficient. Yamato Valley also offers increased low-frequency resonance. If the material has a significant approximation on page 75 V. Description of the invention (70) tt or, the water's special weight 'blade 282 will significantly feel no k 41 ττ under water:! Si from the same elastic constant, low internal resistance' Low-frequency harmonic resonance, as well as controlling the deflection of the lower leaf 1 provide high efficiency. = I 〇 shows a cross-sectional view taken on line 16-16 in the fourteenth figure. :: The thickness of the blade 2 82 is smaller than that shown in the fifteenth figure. In the sixteenth figure, the thickness is reduced because the load on the blade 282 is the largest in the foot pocket and the minimum is near the free end of the blade 282. This is because the force arm on the blade 282 is reduced toward the free end of the blade 282. The degree of tapering from the foot pocket 284 to the free end of the blade 282 can be produced in a > Inf manner. Preferably, the degree of tapering does not cause the thickness of the blade 282 to be too thin. Preferably, the outer portion of the blade 282 has a thickness that is excessively deflected in time. And it is preferable that the bending strength of the leaf near the foot bag is large enough to allow a significant amount of different bending stress to be distributed on the significant part of the blade 282 'so as to achieve the desired bending radius of curvature. This increased leverage acting on the blade 2 82 results in a significant amount of extension and compression where the vertical thickness is significantly greater. In this way, the surface area of the blade 282 oriented to the desired angle of attack, the ability to control the deflection of the blade, and the ability to harmonize with large amplitudes are maximized. μ These cross-sectional views allow the overall cross-sectional size or the local modulus of the load-bearing member to be discussed with respect to the method of the present invention. In the pre-production section of this specification, for the sake of simplicity, this discussion is limited to the relationship between the vertical size of the load-bearing member and the material used to extend the compression capacity. The overall cross-sectional dimension phase a is important because the torsional moment generated on the -beam will generate tensile and compressive bending stresses applied in the direction perpendicular to the cross-section of the beam. The larger the cross-sectional volume, page 76 V. Description of the invention (71) The number of fiber bundles (or extremely small longitudinal elements of a given material) is also greater for individuals that are stressed during f-curves. For a given load, the greater the number of fibers on the beam, the greater the distribution of stress across the cross-section and the smaller the stress on each fiber. For a given load, the smaller the cross section, the greater the stress on each fiber. As mentioned earlier, the maximum stress occurs at the maximum vertical distance above and below the neutral plane of the beam. Therefore, vertical height is important for the method of the present invention. For a given cross-sectional height, increasing the cross-sectional width increases the flexural strength because the number of fibers in the longitudinal direction increases. It was mentioned earlier that by extending the compression range to achieve a given maximum angle of attack for an elastic load member, the vertical dimension of the load member must be able to reach the desired angle of attack when bending around a specific radius of curvature and the material used must be The same process should be used when the load is applied. The difference is that the width and shape of the cross section are now included in the combination. The larger the cross-sectional width, the greater the f-curve stress in a given cross-section, the greater the distribution on the surface. In this way, the stress of each fiber is reduced, so the strain of the primary fiber in the form of extension and / or compression (deformation is such that a load bearing member with a relatively large cross-sectional dimension is vertically vertical); In the same cut ^ (for example, during the light kicking process, / Λ the same blade is deflected 'the material used in the member must be more ductile, that is, the fiber can be extended to produce the vertical dimension of the blade 282 under the newly reduced-bending stress, so that What you need to increase the width 'must use a sufficient vertical height combined with the material to extend and compress == page 77 V. Description of the invention (72) Blade 28 under special kick force 2 Allow the neutral axis to experience orientation compression when approaching or passing the desired angle of attack The surface is sufficiently offset to produce a significant increase in anti-f strength. Figure 17 shows a perspective view in which the fins are kicked in a one-way kick direction 288. It can also be seen that the blade 290 is on each side of the blade 2 90 and There is a longitudinal load-bearing member 292 along the central axis of the blade 290. Each load-bearing member 292 extends from the foot bag 294 toward the free end 296 of the blade 2 90. The blade 29 is scratched by the kicking in the upward direction 288 Song number seventeen The embodiment of the factory shown in Fig. 19 uses fewer blades of 290 wide dimension material, so it may have a relatively high vertical height if necessary. By placing more material at a larger vertical height from the neutral plane of each rib It can be seen in the figure that the blade 290 has a film portion 2 98 extending between each of the heavy ribs 292. The film 298 can be made of a highly elastic material or a significantly rigid material. If a significantly rigid material is used for the film 298, the film 298 is preferably placed The foot bag 2 94 is significantly more flexible near the front half of the blade 290 during use, so that the main energy storage inside each load-bearing member called the foot bag 294 near the front half of the blade 290. Better In particular, the load-bearing member 292 bears the negative pressure generated by the water pressure during kicking, making the method of the present invention significantly usable. Figure 18 shows a cross-sectional view taken from line 18-18 in Figure 17. The rib 292 has a solid f-shaped cross-section. The shape is significantly changed: i: t is large to provide vertical stability and resistance to deformation that should occur during swimming.

Description of the invention (73) It is sufficient to make a change along the length of the rib 29 2 that can interfere with the reduction of the resistance of the method of the present invention. The ribs 292 produced by excessive twisting are vertical, and the materials in the two pieces 292 must be extended and / or compressed to reduce the degree during use. Appropriate design steps are preferably used to ensure that the vertical height of the two sex faces of each of the ribs 292 is kept sufficiently constant during use so that the bending method of the present invention can be maximized. By providing a significant rounded cross-section shape with a significantly large width to height ratio, the rib 292 can provide significantly high stability. The cross section shown in Fig. 18 shows that the film 298 passes through the middle door portion of the rib 292. If the film 298 is made of a substantially extensible material, this method of attaching the film 298 to the rib 292 provides a mechanical bond that enhances chemical bonding. The film 2 98 has holes in the connection points between the ribs 292 and the film 2 98 so that the material in the ribs 2 92 can pass through the holes in the film 298 during the molding process to form a stronger mechanical joint. Any desired combination of mechanical and / or chemical bonding may also be used. If the film 2 98 is made of a relatively rigid and significantly less ductile material, the presence of the film 2 98 in the middle portion of the rib 292 may cause the rib 292 to have a reduced extension along the stretched surface of the rib 292. The compression surface will still compress and reach the maximum compression state that can be used to limit blade deflection and store energy. However, after the neutral axis in the rib 298 is offset toward the compression surface of the rib 298, the height of the film 298 above the neutral axis in the rib 292 determines the amount of elongation along the film 298 required for further bending. The extent to which the material in the film 2 98 can be extended under the load applied to the blade 290 during use determines the amount by which the rib 29 2 can be further bent under an increased load. Therefore, the thin film 298 in the rib 292. V. INTRODUCTION (74) The extensibility of a given material can be used to control blade deflection. If the tensioned surface of rib 2 92 above the neutral surface of rib 2 92 is high enough, the tensioned surface of rib 292 may become fully extended before significant stress is applied to film 298. The nineteenth figure shows a cross-sectional view taken on line 19-19 in the seventeenth figure. It can be seen in this figure that the ribs 29 2 in this part of the blade 2 90 are smaller and have reached a more circular cross-sectional shape. If the film 298 is made of a more rigid material, the outer part of the rib 292 can be closer to an ellipse and not round, because the rigidity of the film 298 provides sufficient support for the outer part of the rib 292 so that it is not used. ^ Significantly twisted. If the film 298 is made of a highly elastic material, the rib member 2 92 has a substantially circular shape in the vicinity of the rib member 29 2. This is because if there is significant twisting of the blades on the ribs 2 9 2 in other parts, this roundness allows the vertical height above and below the neutral plane to be significantly maintained. The circle also provides symmetry to the value of the center of mass axis, so that if any twisting does occur, the rib 292 will not undergo a significant symmetry change relative to the neutral plane, so it will not become unstable and can maintain a significantly high structure Integrity "$ In other embodiments of the cross-sections shown in Figures 18 and 19, the ribs 29 2 above the film 298 can be made of a different material from the lower part of the ribs 292 that exist below the film 298 production. The use of two different materials above or below the film 298 or the use of the same material with different hardness, extensibility or compressibility can allow the blade 2 90 to exhibit different flexural characteristics in the reverse stroke. For example, if the material of the lower part of the rib 2 92 is more compressible than the material of the upper part of the rib 292 ', the tab 29G flexes more when flexed in the downward direction than when kicked in the upward direction. Fig. 20 shows another embodiment of the sectional view shown in Fig. 18, which

Description of the invention (75) The blade 290 has a series of load-bearing ribs 293, which have a distinct semicircular cross-sectional shape and extend above and below the film 2 98. It can be seen that there are three load-bearing ribs 293 'on the upper surface of the blade 290 and two load-bearing ribs 293 on the lower surface of the blade 290. The size of the rib 293 below the film 298 is larger than that of the rib 293 above the film 298. This configuration is only one of many possible configurations of the rib 293 using the method of the present invention. When using the method of the present invention, the ribs 2 9 3 use any desired shape, size, size combination, material combination, or cross-sectional shape. The two large ribs 293 located under the film 2 98 can be designed to have a material volume that is significantly equivalent to the material in the three smaller ribs 293 located above the film 298. The large vertical height within the ribs 2 9 3 below the film 2 98 allows increased stress to be applied to the materials within the ribs. The increased width of the larger ribs 2 3 3 under the film 298 provides additional stability, so that the increased stress caused by the verticality of the ribs during use will not cause significant deformation or twisting of the ribs. The load-bearing members 293 preferably provide the main load-bearing support for the blades 290, so the film 298 is significantly supported by the load-bearing members 293. The other embodiment shown in Figure 20 can be used to generate different blade bending limits for upward or downward movement when needed. The angle between the stomping bag 2g4 and the resting blade 2 90 is only a small deflection for a stroke to achieve a significantly reduced angle of attack relative to the motion between the fins and water during use, and at the same time the blade is resting at 29 The angle requirement is one point when a substantial large blade deflection is required for the reverse stroke. By providing different geometries for the load-bearing ribs on either side of the blade 290, variations in extended compression range can be produced. The rib 293 is present only on the upper surface or the lower surface as necessary. This can further allow the blades to move in opposite directions with a large difference in deflection characteristics. ,

The vertical size of the straight leg titanium "316 vertical film 315 is substantially small, and the rib 3" is added to provide increased compression requirements along the upper and lower portions of the rib 314. For a given material, the smaller the number of ribs 314, the thinner or more flexible the 315 material is, the greater the sag in each rib 314 can be. It can be seen in the figure that the rib 314 has a vertical direction, a cross-section, and a distance: pieces, and a large vertical distance. More material is placed at the vertical distance. Peak extension and compression. Because the aid 314 in this figure is significantly close to the footing 316, the vertical structure of the footing bag 316 provides vertical stability to the portion 314 that is significantly close to the footing 316. This vertical stability provided by the foot pocket 316 structure allows the ribs 31 to 14 to have a smaller horizontal cross-sectional surface size for a given material and a given vertical size.

Description of the invention (77) This vertical stability is significantly reduced when it extends away from the foot bag 316. Therefore, the cross-sectional shape of the rib 314 preferably becomes less circular when the rib 314 extends from the foot pocket 316 to the free end 318 and is closer to a circle. The twenty-third figure shows a sectional view taken on line 2 3-23 in the second figure. The cross-sectional shape of the rib 3 14 in the twenty-third figure is less elliptical than that shown in the twenty-second figure. This allows the rib 314 to have a larger width-to-height ratio, which significantly reduces twisting and avoids deformation. The upper and lower surfaces of the rounded edges of the ribs 3, 4 prevent the vertical height of the neutral surface or the height of the principal axis from bending when the twists occur slightly along the length of the ribs 3 1 4. In the figure, it can be seen that the width of the rib 314 maintains a remarkable strangeness between the twenty-third and twenty-fourth drawings, and at the same time, the degree of the decrease is significantly reduced. This allows the rib 314 to obtain increased vertical stability when the self-supporting foot bag 316 extends to the free end 318, and also experiences a reduction in the effect on the rib 314 when the self-supporting foot bag 316 extends to the free end 318. The small leverage is equivalent to a reduction in bending strength. This same reduction takes place between the twenty-third and twenty-four figures. The twenty-fourth figure shows a sectional view taken on line 24-24 in the twenty-first figure. It can be seen in the figure that the rib 314 is obviously round and has great stability. Since the width-to-height of the rib 31 4 is significantly increased compared to the self-placed bag 316 to the free end 3 18 'the bending strength is gradually decreased toward the free end 318', so that the rib 314 does not excessively flex during a heavy kick. This is because the volume of the material in the rib 314 is maintained toward the free end 318 = maintained large enough to prevent excessive deflection during heavy kicks 1 The rib 314 is fixed: capacity: a significant large-scale extension occurs in the material of the rib 314 And compression 'are applied using the method of the present invention. The twenty-fifth figure shows the implementation of A 丨 two L ^ in the twenty-second figure. 5. Other examples of the implementation of the cross section are not shown in the fifth. (78) Example of the invention. The picture shows the twenty-third picture shown above: Face? 1-shaped load. Ribs 32 °. Twenty-shaped load-bearing members 3 20. Twenty-second plane: Dizi other species / examples, which use other circular embodiments, which are larger than the first figure: the cross-sectional view shown in the twenty-fourth figure load-bearing members. In this embodiment, the circular shape of the ribs 314 shown at the same time ... at the same time, set the foot bag 316 to the free end in the width and Mm pieces to stabilize vertically, and lead the large V substantially circular ribs 32 to provide excellent efficiency storage The large volume of energy provides a directional fiber with a low blocking effect. b Because the bending stress is distributed to a larger amount of length In the example, the reduction in the height of the vertical cross section of the rib 320 is significantly smaller Λ to the rib 314 shown in the twenty-fourth figure. In the twenty-seventh figure, '= Xiang / ΛYudu] is larger near 18, which is based on the birth of the material in the rib 320. It is larger than the twenty-fourth figure to increase the bending strength. Department of origin near 3 8. In the twenty-fifth to twenty-seventh drawings, the volume of the ribs to the free end 318 is reduced, and the reduction is effective. Two to Λ 1 plus the load spans the length of the rib 320 from the foot bag 316 to the free end 318. . Summary, divergence and range J.
