The utility model relates to a high-speed V-shaped boat with a resistance-reducing air cavity, comprising a boat body, a propulsion system and an air supply system arranged in the boat body. The high-speed V-shaped boat with the resistance-reducing air cavity is characterized in that the bottom surface of the boat body is provided with a concave air cavity; two side fins forming the air cavity are arc-shaped; the width of the air cavity increases gradually from the head part of the boat body to the tail part of the boat body; the rear part of the air cavity is provided with a tail protuberance; and an air inlet for leading the air supply system to supply air to the air cavity is arranged at the fault of the air cavity. For the high-speed V-shaped boat with a resistance-reducing cavity, a reasonable air cavity structure is arranged, and the rear part of the air cavity is provided with the tail protuberance, therefore, the stability of the air in the inner layer of the air cavity and the resistance-reducing function of the air cavity can be ensured, the friction resistance when the boat body runs is effectively reduced, the fuel is saved and the propulsion efficiency is effectively improved.
Description
Technical field
The utility model relates to a kind of high-speed boat, especially relates to a kind of air cavity drag-reducing high-speed V-type ship of friction drag when utilizing air cavity to reduce the hull navigation.
Background technology
At present, some large ships are provided with air cavity in the bottom, and in air cavity, inject air, thereby reduce the area of contact between hull bottom surface and the water, friction drag when navigating by water to reduce hull, fuel saving also effectively improves propulsion coefficient, and a kind of hull bottom is provided with the ocean steamer of a plurality of air cavitys as U.S. Pat 3595191 discloses.This air cavity that constitutes with smooth hull bottom surface and vertical partition wall is only applicable to the lower boats and ships of the speed of a ship or plane, if be used for the complicated V-type ship of hull bottom shape, especially during the higher high speed V-type ship of the speed of a ship or plane, can cause the air in the air cavity to leak in a large number, make the too high power of propulsion system loss, and can't produce tangible drag-reduction effect.
Summary of the invention
The applicant has carried out research and has improved at above-mentioned problem, and a kind of air cavity drag-reducing high-speed V-type ship is provided, and rational air cavity structure is set, the friction drag when effectively reducing the hull navigation, and fuel saving also effectively improves propulsion coefficient.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of air cavity drag-reducing high-speed V-type ship, comprise hull, propulsion system and be arranged on the interior gas supply system of hull, described hull bottom surface is provided with the air cavity of indent, two side of a ship lateral fins that constitute described air cavity are curved, the width of described air cavity becomes big by the hull stem gradually to the hull afterbody, the rear portion of described air cavity is provided with the afterbody projection, is used for gas supply system is arranged on faulted-stage place from air cavity to the admission port of air cavity air feed.
Further:
Described air cavity by the center buttock place of hull vertically cut apart fin and at least one is divided into a plurality of little air cavitys perpendicular to the horizontal partition fin of vertically cutting apart fin.
Be respectively equipped with air extractor vent described vertically cutting apart on fin and the described horizontal partition fin, and air extractor vent is communicated with each adjacent little air cavity.
Described air extractor vent is arranged on the described junction of vertically cutting apart fin and described horizontal partition fin and hull bottom surface.
Described afterbody projection is wedge, and the height of described afterbody projection is by reducing gradually to both sides in the middle of the hull bottom surface, is reduced gradually to the front portion by the rear portion of hull bottom surface.
The surface of described afterbody projection is the plane.
Technique effect of the present utility model is:
The disclosed a kind of air cavity drag-reducing high-speed V-type ship of the utility model, rational air cavity structure is set, and the afterbody projection is set at the air cavity rear portion, can guarantee the drag reduction effect of stablizing and guarantee air cavity of air cavity inner air, friction drag when effectively reducing the hull navigation, fuel saving also effectively improves propulsion coefficient.
Description of drawings
Fig. 1 is an overall structure scheme drawing of the present utility model.
Fig. 2 is a hull bottom surface structural representation.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.
As shown in Figure 1, 2, the utility model comprises hull 1, propulsion system 2 and is arranged on gas supply system 3 in the hull 1, hull 1 bottom surface is provided with the air cavity 4 of indent, two side of a ship lateral fins 401 that constitute air cavity 4 are curved, the width of air cavity 4 becomes big by the hull stem gradually to the hull afterbody, such air cavity version meets the navigation and the constructional feature of high speed V-type ship, reduces gas in the air cavity 4 in the underway leakage of high speed, guarantees the effect of drag reduction.The rear portion of air cavity 4 is provided with afterbody projection 6, be used for gas supply system 3 is arranged on faulted-stage 403 places from air cavity 4 to the admission port 7 of air cavity 4 air feed, in the present embodiment, afterbody projection 6 is wedge, the height of afterbody projection 6 reduces to both sides gradually by in the middle of the hull bottom surface, rear portion by the hull bottom surface reduces gradually to the front portion, and the surface of afterbody projection 6 is the plane.Afterbody projection 6 mainly contains two effects, at first, with air cavity 4 gas leakages guiding hull 1 both sides, it is leaked from both sides, the interference of gas leakage to the screw propeller of afterbody propulsion system 2 reduced, secondly, the wedge structure of afterbody projection 6 can provide certain bottom lift, and the resistance that reduces hull is played a role.Air cavity 4 is divided into 4 stingy chambeies 402 by vertically cut apart fin 9 and one at the center buttock place of hull 1 perpendicular to the horizontal partition fin 8 of vertically cutting apart fin, and the quantity that is provided with of horizontal partition fin 8 is determined according to the length of hull.In the present embodiment, vertically cut apart on fin 9 and the horizontal partition fin 8 and be respectively equipped with air extractor vent 5, air extractor vent 5 is communicated with each adjacent stingy chamber 402, air extractor vent 5 is arranged on the junction of vertically cutting apart fin 9 and horizontal partition fin 8 and hull bottom surface, that is to say that air extractor vent 5 is arranged on vertically cuts apart fin 9 and place, horizontal partition fin 8 close hull bottom surface.Hull takes place in wave when oblique than heavy list, leakage of air can take place in one or several independently stingy chamber 402, thereby cause the instability and the overbalance of hull resistance and buoyancy, air extractor vent 5 is communicated with each adjacent stingy chamber 402, each stingy chamber 402 is replenished rapidly mutually by air extractor vent 5, it is stable that air layer in each stingy chamber 402 is remained, thereby keep the stable and balance of hull resistance and buoyancy.Test result shows that the escape of air in the air cavity of the present utility model is little, and drag-reduction effect is obvious.
