Abstract
The utility model discloses a transition deep V line type suitable for a medium-low-speed ship. The seakeeping of the ship can be improved through the transition deep V line type, and low-speed resistance is small. According to the transition deep V line type suitable for the medium-low-speed ship, a V shape is used on the middle-back portion section of the ship. A bottom oblique-rising angle beta in the middle is 20-25 degrees. By lifting the bottom line type from the middle portion to the tail portion gradually, a tail portion bottom oblique-rising angle beta becomes 0-5 degrees in a smooth-transition mode. By reducing the folding angle line width from the middle portion to the tail portion gradually, the ratio of the tail folding angle line width to the middle folding angle line width reaches 0.7-0.8 in a smooth-transition mode. The transition deep V line type is used in the medium-low-speed ship, the vertical acceleration of the ship can be lowered, the seasickness rate is lowered, the resistance identical to a circular bilge ship type is achieved, a non-storing type fin stabilizer can be well arranged below a middle angle folding line of the transition deep V line type, rolling motion can be lowered, and accordingly ship seakeeping characteristics are improved.
Description
Technical field
The utility model relates to seaworthiness performance technical field, is specifically related to a kind of dark V line style of transition that is applicable to middle low speed boats and ships.
Background technology
Traditional dark V line style generally refers to that deadrise angle is the knuckle line style of 20 °～25 °, because having in good seakeeping performance and stormy waves, it can keep the advantages such as the high speed of a ship or plane, on miniature high-speed naval vessel, obtained in recent years good development prospect, therefore traditional dark V line style is mainly used in high speed vessel, its dark V line style is consistent with the feature of high speed vessel, mainly possess following characteristics: the one, because the speed of a ship or plane of high speed vessel is high, diameter of propeller is little, axle is that angle is larger, line type stern need not be lifted very high like this, buttock line is more straight, and afterbody ramping angle can be larger; The 2nd, when higher Fu Rude counts Fr, afterbody knuckle can be wider, and near Fr=1.0, afterbody knuckle width and middle part knuckle width are almost equal, can form longer virtual length, reduces high speed resistance; The 3rd, due to the needs that displacement is controlled, traditional dark V line style drinking water is more shallow, does not generally establish plate keel.For middle low powered, in order to improve propeller efficiency, wish to reduce propeller speed, increase diameter of propeller, if adopt traditional dark V line style must face screw propeller Layout Problem, and due to the dark V line style of tradition, still water resistance is higher than garden chine type when the middle low speed, therefore adopt the short knuckle line style of Yuan Bihuo garden bilge as the middle low powered that moral number is less than 0.5 for length Fu, but garden chine type seakeeping performance is poor.
Summary of the invention
In view of this, the utility model provides a kind of dark V line style of transition that is applicable to middle low speed boats and ships, and seakeeping performance and the low speed resistance that can improve boats and ships are little.
The dark V line style of transition that is applicable to middle low speed boats and ships of the present utility model, in the postmedian section employing V-type of boats and ships; The deadrise angle β at middle part is 20 °～25 °; By raising gradually middle part to the bottom line style of afterbody, make afterbody deadrise angle β smooth excessively to 0～5 °; By progressively reducing middle part to the knuckle live width of afterbody, make the ratio of afterbody knuckle line width and middle part knuckle line width smooth excessively to 0.7～0.8.
Wherein, non-extendible stabilizer can be installed under the knuckle line of middle part.
Can also the reverse keel of hyper-base line be set at foremost part of ship.
Beneficial effect:
Postmedian section adopts V-type, has improved the seakeeping performance of boats and ships, by raising middle part to the bottom line style of afterbody and reducing middle part to the knuckle live width of afterbody, improves form resistance, reduces marine low speed resistance, suitable with garden bilge ship type low speed resistance.Meanwhile, raise gradually bottom line style and can meet major diameter screw propeller layout, improve propeller efficiency.Under the knuckle line of middle part, be applicable to non-extendible stabilizer is installed, can reduce rolling motion, thereby improve seaworthiness performance.
Accompanying drawing explanation
Fig. 1 is the body plan of the dark V line style of the transition of the utility model boats and ships.
Fig. 2 is the elevations of the dark V line style of the transition of the utility model boats and ships.
Fig. 3 is the Half Breadth Plan of the dark V line style of the transition of the utility model boats and ships.
The specific embodiment
Below in conjunction with the accompanying drawing embodiment that develops simultaneously, describe the present invention.
The invention provides a kind of dark V line style of transition that is applicable to middle low speed boats and ships, as shown in FIG. 1 to 3, in the postmedian section employing V-type of boats and ships, the rough water quality advantage of the dark V line style of inheriting tradition; The deadrise angle β at middle part gets 20 °～25 °, keep suitable with the dark V line style deadrise angle of tradition, and this ramping angle is convenient to install non-extendible stabilizer under the knuckle line of middle part; By raising gradually middle part to the bottom line style of afterbody and reducing knuckle live width, reach from middle part to the successively decreasing of afterbody deadrise angle, meet screw propeller layout; Gradually reduce afterbody knuckle line width, improve form resistance, reach the low speed resistance performance suitable with garden bilge ship type, from considering of experimental study and general layout (being mainly the layout of tail undercarriage), raise gradually bottom line style, make afterbody deadrise angle β smooth excessively to 0～5 °, and progressively reduce middle part to the knuckle live width of afterbody, make the ratio of afterbody knuckle line width and middle part knuckle line width smooth excessively better to 0.7～0.8 o'clock effect.Wherein, stem line style fairing transition, cancels stem knuckle gradually, and line style is smooth, improves stem and attacks, and increases floor space, facilitates anchor to arrange.Foremost part of ship can arrange the reverse keel of hyper-base line.
Middle low powered adopts the dark V-type line style of transition, can reduce boats and ships vertical acceleration, reduces seasick rate, and reaches the resistance performance suitable with garden bilge ship type; Under the knuckle line of the dark V-type line style of transition middle part, be applicable to non-extendible stabilizer is installed, can reduce rolling motion, thereby improve seaworthiness performance.
According to model investigation, estimate that seakeeping performance improves more than 20% than conventional round-bilge ship type.Resistance is in length Froude number 0.3～0.4 scope, and resistance is suitable with the resistance with the round-bilge ship type of yardstick and displacement, and slightly better than slack bulge hard chine form resistance.
In sum, these are only preferred embodiment of the present invention, be not intended to limit protection scope of the present invention.Within the spirit and principles in the present invention all, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
