Abstract

The invention discloses a compressed air catapult used for takeoff of an aircraft on an aircraft carrier. According to the compressed air catapult, an extensible pipe is used for conveying gas, and high-pressure gas forms jet streams through a nozzle of a thrust generator to be jetted to a fixed device so as to generate huge thrust. The compressed air catapult has the advantages of being easy to manufacture and operate, easy and convenient to control, easy to maintain, low in manufacturing cost, and more economical than a steam catapult made in America, and the efficiency of the compressed air catapult reaches up to 85%.

Description

Compressed-air catapult

One, affiliated technical field: the present invention is a kind of for the aircraft carrier ejector manufacture method of use of taking off of boarding a plane.

Two, technical background: only have at present the U.S. using steam catapult and Electromagnetical ejector, I feel too complicated in research steam catapult, too difficult manufacture.Want to design a kind of easy ejector that is easy to manufacture and control, the target that Take me as I am is pursued, through arduous thinking, has finally found out this being easy to and has manufactured, than steam catapult advanced person's manufacture method.

Summary of the invention:

1, with the pipe of more piece different-diameter, be assembled into a kind of telescopic pipeline, with it, carry out conveying high-pressure gas;

2, with gradually following the nozzle of formula, high pressure gas are become to the high pressure draft of meter per second more than 200, be ejected on baffle plate and produce that huge thrust removes to promote aircraft on aircraft carrier deck and thrust generator synchronously rapidly moves ahead, when reaching the speed of taking off, aircraft just flies blue sky.

Four, technical scheme: the present invention is formed by following device combinations.

1, telescopic gas line: it is that pipe by more piece different-diameter assembles, and sees Fig. 1.1# pipe can all stretch in 2# pipe; 2# pipe all can be retracted in 3# pipe again ..., a bracket is equipped with in one end of every pipe joint, and bracket two ends are rollers, and it plays support tube weight and is convenient to orbit.Cradle also will have water-tight equipment.Pipeline overall length should, than many 15～20 meters of design length (tentative 150 meters), be made buffer action.Pipeline shortest length is 1 pipe joint length and each bracket length sum.Its one end is connected with gas transmission valve with storage tank, and the other end is connected to air inlet place of thrust generator;

2, thrust generator: see accompanying drawing 2.It is comprised of a plurality of nozzles that reduce formula, and every layer of nozzle produces tens high velocity airs to meter per second more than 200 with difference of pressure, is ejected on baffle plate and produces huge thrust.Its lower end has four wheels to be convenient to orbit;

3, locking mechanism: be installed together with thrust generator, he is the position that sticks aircraft nose wheel support and axle, aircraft can not be moved forward and backward, and the front and back wheel of aircraft all can be moved on aircraft carrier deck.Manual operation when pin is determined aircraft, electric operating while unclamping;

4, speed reduction gearing: be to be assembled by the principle of scalable gas piping by long 2～3 meter of 4～5 pipe saving.Before use, can fill the gas of certain pressure to increase resistance;

5, air compressor: select 100kg/cm ²power be 1200 kilowatts 2～3, select 100kg/cm ²pressure be to want to make it can produce the thrust of 1000 tons.The energy that the large ability of thrust can need while meeting taking off of multi-model more.I have good reason can make manufacturer production go out this equipment technically;

6, storage tank: the volume of storage tank is larger, the energy of storage is more, with 200m ³, 100kg/m ²for example, after it can make to destroy 10 stream takeoff 3 sorties, its pressure still can remain on 60kg/cm ²if long more than 100 meters in aircraft carrier one one of side-lower installation, container is 200m ³pipeline as the use of gas storage, simply too much with isometric storage tank than manufacturing;

7, scalable gas line and thrust generator are the cores of this ejector, if although install above deck conveniently, can not maintain secrecy.So should be arranged on below aircraft carrier deck.And open above deck the crack of 3 centimetres of long 170 meters of moneys, and reveal just long 50cm above deck, high 20cm, iron plate of thick 2cm and iron plate are gone up several parts of locking mechanism.Disguised just large like this.

Five, principle of work (specific embodiments):

1, before startup, aircraft should be stuck in locking mechanism; Air compressor starts; Aircraft is in takeoff condition;

2, start.Press the button, aero-engine startup, gas line valve open, high pressure gas from storage tank through valve, along the huge thrust producing after scalable gas line enters thrust generator, promoting aircraft and rapidly moving ahead above deck, gas line is also by continuous extension elongation, when running to certain distance (tentative 150 meters), aircraft and thrust generator are stepped on and are all reached while taking off required speed, at this moment pressing the button (or automatically) locking mechanism just unclamps, air intake valve is closed simultaneously, speed reduction gearing also starts, and aircraft has just flown to blue sky;

3, slow down.After taking off, thrust generator etc. constantly move ahead because of inertia, and speed reduction gearing is constantly compressed, and resistance is increasing, finally forces thrust generator to stop getting off;

4, return.Compressed air has stored a large amount of energy and when thrust generator stops moving ahead, has obtained the chance discharging in speed reduction gearing, just thrust generator and gas line is together rebounded to going back.If not in place, with winch, retract;

5, regulation and control.Different type of machines required thrust is different, and the aperture of controlling gas transmission valve has just reached this object.Because the large suction quantity of valve opening is just many, the thrust of generation is just large, otherwise suction quantity is little, and the thrust producing is just little.

Six and use vapor phase ratio: on aircraft carrier, an airplane takes off only 4～5 seconds used time, in order to guarantee that every airplane has enough steam pressures while taking off, must constantly in boiler, add fuel to guarantee pressure, the pressurize of insulation ability, this must consume a large amount of fuel more.And pressurized air does not just need insulation, this is its advantage.Thereby the very large expense of saving every day.

The method of this manufacture ejector, has and is easy to manufacture, convenient operation and control, and cost low (approximately 5,000,000 yuan), efficiency can reach the advantage such as 80%.
