Abstract
The utility model relates to a non-air-blower side wall type hydrofoil hovercraft which comprises a hovercraft body, a power device and a hydrofoil. The hovercraft body is composed of two primary hovercraft bodies and a main hovercraft body. The two primary hovercraft bodies are symmetrical and fixed on a bottom face of the front end of the main hovercraft body. An outer side wall of each primary hovercraft body and an outer side wall of the main hovercraft body are located in the same plane and extend downwards to form a main side wall. The hydrofoil is arranged at the bottom face of the tail portion of the main hovercraft body and is connected with the bottom face of the main hovercraft body through connecting rods. The power device is arranged at the tail portion of the main hovercraft body. Due to the fact that the hydrofoil is combined with a hovercraft so that the non-air-blower side wall type hydrofoil hovercraft has the advantages of being small in water resistance and fast in sailing speed when in sailing which are possessed by the traditional hydrofoil and the traditional hovercraft, meanwhile overcomes the defects that the traditional hydrofoil is small in load and high in hydrofoil requirements and the traditional hovercraft is high in energy consumption, large in noise and poor in stability. An air blower required by the traditional hovercraft is saved so that manufacture cost and operation cost are greatly reduced.
Description
Technical field
The utility model relates to a kind of instrument that travels waterborne, particularly relates to a kind of without blower sidewalls formula hydrofoil air cushion vehicle.
Background technology
There is shortcomings in air cushion vehicle of the prior art, wherein topmostly when navigating by water, air cushion vehicle need to consume more lift power, for example the lift power of surface effect vehicle has accounted for 40% ~ 50% of gross horsepower, this just so that its performance driving economy greatly descend, be unwell to use cost than more sensitive application scenario, in order to reduce structural weight, improve performance driving economy, air cushion vehicle generally adopts weight-saving aluminum alloy or composite material to build, cost is high, maintenance cost is also high, be unfavorable for maximizing, and the high speed of air cushion vehicle also depends on the running state of its air cushion, when sea situation is higher, because the air cushion integraty is destroyed, and can not keep the good effect that hovers, the air cushion vehicle of existing scale all can occur to a certain degree, or even the speed of a ship or plane by a relatively large margin descends.
Hydrofoil boat is a kind of under common hull, the boats and ships that are immersed in the hydrofoil in the water are installed, and the major defect of hydrofoil boat is: when normally navigating by water, the weight of ship relies on less hydrofoil and shore supports thereof fully, in order to reduce resistance, hydrofoil and pillar have all adopted lightweight construction usually, intensity is limited, can not support very large weight, so the scale of common hydrofoil boat is generally all smaller, if further improve speed, the current on hydrofoil surface easily separate under high speed, meiobar can produce cavity and impact, and the eroding water wing structure is when serious even cause hydrofoil to damage.
China Patent No. is 201210170599.4 to disclose a kind of nothing fan air cushion vehicle that hovers, the madial wall of its lash barge body extends to below the bottom surface, so that the resistance larger to water generates causes the turning radius of ship larger, the navigation alerting ability is relatively poor, is unfavorable for travelling in narrow river; The midway location at rear portion, main body bottom surface is equipped with vertically continuously, also inserts vertically downward the rigidity fin keel in the water in addition, its shortcoming mainly is to cause between lash barge body and the main body on the one hand to be isolated, because the wind energy power of drinking of lash barge body is little, it is limited that main body is drunk wind energy power; Three air cushions that are separated from each other of the bottom of lash barge body and main body formation so that air cushion overall width and the gross area reduce, further reduce the air cushion effect of hull bottom on the other hand.
Summary of the invention
The utility model is in order to address the above problem, providing a kind of combines hydrofoil boat and air cushion vehicle, the advantage that resistance is little, the speed of a ship or plane is fast of water when both having possessed traditional hydrofoil boat, air cushion vehicle navigation, overcome simultaneously that traditional hydrofoil boat load-carrying is little, the hydrofoil requirement is high, traditional air cushion vehicle energy consumption is high, noise large, the shortcoming of poor stability with overcoming, and saved the desired blowing engine of traditional air cushion vehicle, greatly reduce manufacturing cost and operation cost without blower sidewalls formula hydrofoil air cushion vehicle.
The technical solution of the utility model is:
A kind of without blower sidewalls formula hydrofoil air cushion vehicle, contain hull, engine installation and hydrofoil, described hull is made of two sub-hulls and a main body, two mutual symmetries of sub-hull also are fixed on the bottom surface of main body front end, the lateral wall of described lash barge body and the lateral wall of main body consist of major side wall at grade and to downward-extension, the bottom surface of described main body afterbody is provided with a hydrofoil, described hydrofoil is connected with the bottom surface of main body by pipe link, and described engine installation is located at the afterbody of main body.
Described lash barge body length is 1/2nd of main body length, and the width of lash barge body is 1/5th of main body width.
The bottom surface of described main body is horizontal surface, the bottom surface of described lash barge body be lower than main body the bottom surface and with the angle of horizontal bottom be 3 ° ~ 5 °.
The bottom surface angle of described major side wall and main body is 5 ° ~ 8 °.
Described engine installation is the water screw propeller that is installed in main body afterbody bottom, perhaps for being installed in the air screw on the main body afterbody.
Useful good effect of the present utility model is:
The utility model without blower sidewalls formula hydrofoil air cushion vehicle in when navigation, the lateral surface of main body and the fore of facing upward be common to be formed forwards between uncovered mattress lift-off of drinking wind, air enters hull bottom from hull the place ahead, and the sidewall of hull both sides inserts in the water, the both sides that guaranteed the hull below are air tight, thereby so that it is compressed to enter the hover air in space of hull bottom, form the high pressure air cushion, hull is lifted, thereby minimizing contacts with water, reduce and water between resistance, propulsion coefficient is high, route speed is fast.
2. the utility model has saved the blowing engine of traditional air cushion vehicle without blower sidewalls formula hydrofoil air cushion vehicle, and when navigation, the hull propulsion coefficient is high, and energy consumption is low.
3. the utility model is provided with hydrofoil at the afterbody of hull, utilizes the further lifting hull of buoyancy of water, and minimizing contacts with water, and then the resistance of minimizing water, the speed of a ship or plane of raising ship, and also the bottom surface of hull is the plane, compare traditional sharp hull bottom, navigate by water more steadily, be not easy to tumble.
