Abstract
The present invention relates to a low-resistance general displacement new ship model. It is characterized by that its entrance interior possesses axially-symmetrical arranged oblique variable-section flow channels to form passive ram diversion or active ram diversion; equidimension mortar stern and bulb bow articulated coupling forms the tandem multihull ship so as to obviously reduce wave-forming resistance of general ship, broaden the applicability of high speed-length ratio and high form coefficient and improve low-consumption, maneuverability and seaworthiness.
Description
The present invention relates to the common water surface displacement boat of low resistance.
Main resistance when wave making resistance is the navigation of normal discharge type shipping high speed, though the resistance measure falls in several years employing bulbous bow etc., wave making is still the biggest obstacle of restriction normal discharge type ship speed.
The objective of the invention is: the new ship type of common water surface discharge type that reduces wave making resistance is provided.
The object of the invention realizes like this: rotational symmetry is provided with oblique punching press shunting, jet flow runner in the entrance of vessel hull, jet flow is established propelling unit in the road, in the midship outgate, the limit installs water conservancy diversion, throttle disk respectively, ship stern rectangle mixed flow mouth in parallel both sides, base are installed the thrust vectoring type respectively and are turned to rudder, pitching stabilization fin, rudder, fin blade face are suitable with the external plate of stern, runner transition light respectively, constitute passive, active punching press shunting, spray pattern low-resistance ship; The first ship of entrance of vessel punching press spray pattern and middle ship, middle ship and tail ship are processed into respectively with yardstick mortar type stern, ball-type bow, make forward and backward ship stern, bow is close to and along the flat longitudinal axis articulated type of its concyclic edema with the heart involved mechanical attachment, the mortar stern is established assistant steering device, constitutes many builds of file low-resistance ship.
The invention has the advantages that: significantly reduce common water surface displacement boat wave making resistance, widen high speed length ratio, high shape coefficient Applicable scope, improve low consumption, motor-driven, seaworthiness overall performance.
The invention process is for example shown in the accompanying drawing 1~9, among its Fig. 1 (side-looking): 1 conventional bulbous bow, 2 punching type inflow port, 3 punching press by-pass type back taper runners, 4 outgates, 5 deflecting plates, 6 stern runners are inhaled head piece, 7 sterns advance variable section runner, 8 pitching stabilization fins, 9 tail cones, 10 rectangles mixed flow mouth in parallel and thrust vectoring type turn to rudder, 11 rudderposts, 12 stern outside plates are among Fig. 2 (half-breadth): 13,14 conventional bracing struts, slurry axle and propeller, 15 conventional worm gears, worm transmission pair, water conservancy diversion rudder in the middle of 16, Fig. 3 are that Fig. 1 example is amplified cross-sectional molded lines; Among Fig. 4 (side-looking): 1,3,4 implications are respectively aerofoil profile nose bow, punching press jet flow variable section runner, flow jeting port, the 17 conventional electronic or reciprocal operating controls of hydraulic pressure, 18 throttle disks, 19 watertights and slip inhibiting device, 20 entrance of vessel ship hull plates, fracture alignment left side map interlinking 1 routine after run or the conventional stern type that advances among the figure, among Fig. 5 (half-breadth): 13 implications are band center dunce cap slurry bracing strut, and Fig. 6 is that Fig. 4 example is amplified cross-sectional molded lines; Among Fig. 7 (side-looking): 21 conventional oblique miniwatts are assisted hydraulic efficiency jet propulsion system, 22,30 first ships, middle ship is with yardstick mortar type stern, 23 ellipse taper crossover ports, 24, ship in 31, the tail ship is with yardstick ball-type bow, 25 articulated type mechanical couplings (E-E analyses and observe middle implication for connecting pull bar or drag-line), 26 equal-size cotyle-sterns, the concyclic heart of ball bow, 27 connecting device two ends water-tight compartments, 28 auxiliary heels, 29 auxiliary elevators, 32 pluck and unload the connecting device access hatch cover, 33 elastic caoutchoucs and stiffness bearer, 34 routines can be plucked and be unloaded joint, 35 elasticity watertight covers, and 36 mortar shapes turn to cushion block, 37 locking pieces, 38 articulated type steering balls, 22 first ship line of rupture map interlinkings to the right, 4 routine punching press spray pattern entrance of vessel among the figure, 31 tail ship line of ruptures meet raft body and conventional stern type, Fig. 8 of advancing left, 9 be respectively shown in Figure 7 among ship half-breadth and mortar stern, the cross-sectional figure of ball bow.
In the embodiment of the invention, Fig. 1~3,4~6,7~9 are respectively passive punching press shunting, active punching press jet flow, many bodies of file low-resistance ship type, its characteristic meaning is respectively: during the navigation of Fig. 1 example, inflow port fluoran stream surface inner fluid is rushed in back taper type runner (the diffusion type: the outgate cross-sectional plane is greater than the inflow port cross-sectional plane) and is flowed out by outgate, this part fluid produces wave making resistance (runner influent stream angle, inflow port place is very little) hardly, certainly will cut down the interior total wave making energy of entrance of vessel fluoran stream surface and cause the boats and ships total drag and significantly reduce; Establishing the propelling unit work done in Fig. 4 example jet flow road (accelerating type: the outgate cross section is controlled) is more conducive to high speed length ratio boats and ships shunting and falls resistance, the built-in propeller in jet flow road advances to be beneficial to and takes existing marine technology (its runner connection is established Electromagnetic Propulsion and will be had more comprehensive advantage, but need treat that this type of technical application is ripe time) in the legend; Make deflecting plate work individually or simultaneously can suppressing respectively boats and ships to float outward and shorten coasting distance when just changing reversing, can make its concordant flow resistance that reduces in deflecting plate outside, water sucking mouth when 21 water injecting systems are not worked with ship hull plate; Make mixed flow mouth in parallel both sides turn to the rudder lagging edge in the same way or action simultaneously inwardly can obtain vectorial thrust respectively and improve propeller low speed operating mode efficient, move also this function of tool after making throttle disk; The ship stern is in trough, crest pitching stabilization in season fin lagging edge, upwards can alleviate boats and ships pitching (get dark its inflow port of V-type stem also be beneficial to suppress pitching) respectively downwards, and seamed edge suitably extends forward and then is equal to deadwood under the tail cone; Fig. 7 example mortar stern ball bow connects and has " universal " and turn to function and immersion joint vortex drag very little, and full ship is suitable gets aspect than improving the speed of a ship or plane, cutting down the consumption of energy; The present invention is applicable at a high speed, higher speed normal discharge type boats and ships; Wherein Fig. 1 for example is used for that the not high occasion of maneuverability requirement is appropriate to the occasion gets conventional stern type and reduce the shipbuilding cost as far as possible; Fig. 7 for example is used for that frequent high sea condition navigation is appropriate to the occasion only to be unified into catamaran with the initial and end ship, is used for rivers shipping etc. and can be connected in series the more piece ship and constitutes and drag top fleet.
