Description

Steam catapult

Technical field

The utility model relates to a kind of steam catapult, a kind of steam propulsion ejector that takes off from the aircraft carrier deck especially for aircraft.

Background technology

The form that aircraft takes off from the aircraft carrier deck has two kinds at present.The one, the sliding formula of jumping is taken off, and the 2nd, catapult-assisted take-off.Catapult-assisted take-off is stronger than the sliding formula lift-off technology advantage that jumps, and the U.S. uses the catapult-assisted take-off technology, because relate to national defense safety, this technology can't be used for reference and also can not buy, and therefore develops the steam catapult that Chinese aircraft carrier uses and has crucial meaning.

Summary of the invention

The purpose of the utility model provides a kind of steam catapult, uses steam catapult can save the space of taking off, and carrier-borne aircraft quantity is increased, and make the various fixed wing aircraft realize going up warship and take off, and the efficient height that takes off.

The technical scheme of the utility model is: a kind of steam catapult, comprise steam propulsion system, emission coefficient, ejection system, and it is characterized in that: steam propulsion system is provided with bonded assembly steam generator, vapour storage tank, booster jar, Steam Recovery cylinder successively; Ejection system be provided with by stent support and the guide rail that is connected with the deck, with the shuttle of guide rail sliding block joint, be provided with jig above the shuttle, be provided with the chassis below; Emission coefficient is provided with two cylinders side by side, and the admission port of two cylinders is connected with the booster jar delivery piping, and the booster jar delivery piping is provided with the emission control valve; The exhausr port of two cylinders is connected with the delivery piping of vacuum pump, Steam Recovery cylinder, vapour storage tank successively; Piston is housed in the cylinder, and the piston front is connected through piston rod and shuttle chassis, and the cylinder rear is provided with the capstan winch that resets; Cable wire one end and shuttle chassis are connected, and the other end is connected with the capstan winch that resets.Described shuttle both sides are provided with groove, and guide rail is embedded connection in the shuttle groove.

The high pressure steam that present technique is produced by booster jar promotes the piston of emission coefficient, produces powerful thrust, promotes ejection system and goes up to the air airplane catapult.Present technique is compared advantage with the deck cunning formula of the jumping mode of taking off:

1, the sliding formula deck start take off distance that jumps is long, and the 3rd takeoff point has occupied very big between deck space at 195 meters, and carrier-borne aircraft quantity is reduced, and present technique can be practiced thrift out more space, carrier-borne more fighter plane.

2, the aircraft of the sliding formula deck start that jumps can not be filled it up with oil, influences combat radius, makes the safety of aircraft carrier can not get ensureing.Can not carry completely various guided missiles, make fighter plane bring into play not maximum operational performance.The aircraft that present technique is launched can be filled it up with oil, overworks the guided missile of various models, gives full play to the operational performance and the combat radius of aircraft.

3, the sliding formula deck start mode that jumps because the various fixed wing aircraft can't be gone up warship and take off, greatly influences the fighting efficiency of aircraft carrier.For example: early warning plane, antisubmarine plane, electronic warfare air plane, fuel charger, medium transport aircraft etc.Present technique has solved the difficult problem that fixed wing aircraft takes off preferably on aircraft carrier, every aircraft carrier of present technique is installed four ejectors, can launch eight airplanes in 1 minute, and efficient is very high.Large-scale fuel charger can take off on aircraft carrier, refuels for opportunity of combat, makes operational aircraft that bigger combat radius arranged.Medium transport aircraft takes off on aircraft carrier, can effectively improve the supply of weapons and ammunitions and goods and materials.Can also make warship on the large-scale prior-warning plane, detection range is farther, and aircraft carrier is safer, and the fixed-wing antisubmarine plane can take off on aircraft carrier, has increased antisubmarine ability, makes safety under water obtain guarantee.

The specific embodiment

Steam catapult comprises steam propulsion system, emission coefficient, ejection system.Steam propulsion system is provided with steam generator 15, vapour storage tank 16, the booster jar 17 of plumbing connection successively, Steam Recovery cylinder 12; Ejection system is provided with the guide rail 3 that is supported and be connected with deck 2 by support 1, and guide rail is embedded sliding block joint in the groove of shuttle 4; Be provided with jig 5 above the shuttle, be provided with chassis 6 below; Emission coefficient is provided with 8, two cylinders 8 of two cylinders side by side and is contained in the cylinder frame 13, and the admission port of two cylinders is connected with booster jar 17 delivery pipings; The booster jar delivery piping is provided with emission control valve 18; The exhausr port of two cylinders is connected with the delivery piping of vacuum pump 11, Steam Recovery cylinder 12, vapour storage tank 16 respectively successively, and vapour storage tank 16 is provided with the recovered steam control cock, and piston 9 is housed in the cylinder; The piston front is connected through piston rod 7 and shuttle chassis 6; The cylinder rear is provided with the capstan winch 14 that resets, and cable wire 10 1 ends and shuttle chassis 6 are connected, and the other end is connected with the capstan winch 14 that resets.

During work, the powerful high-pressure water vapor entering vapour storage tank that is produced by steam generator stores, again through booster jar; Adjust air pressure, different according to the aircraft weight of emission, it is for use to modulate needed air pressure; Be located at above the shuttle jig be parked in the deck on the aircraft nose wheel that need launch be connected, the operator presses emission switch, the piston that high pressure steam promotes emission coefficient in cylinder rapidly forward; The shuttle that makes the piston rod thrust ejection system along guide rail rapidly forward and promote aircraft and in two seconds, launch lift-off, speed per hour can reach more than 265 kilometers, starts vacuum pump simultaneously; The air that piston is moved in the cylinder of the place ahead is extracted into the Steam Recovery cylinder, reduces piston forward or the resistance of the operation that resets, and it is to rely on the capstan winch that resets to rotate the rolling cable wire that shuttle resets; Cable wire pulling shuttle is to the preceding position of emission, and shuttle back into the piston initial position to piston simultaneously, booster jar adjustment air pressure; Preparation is emission next time; Storage tank is opened switch, and making storage tank fill it up with steam is the ready work of emission once more, and these operations are all through launch control console detection, judgement, control.
