Description
Technical field
The present invention relates to a kind of for large and medium-sized carrier-borne aircraft the jato unit at carrier-based.
Background technology
Jato unit is the accessory appliances that aircraft is realized ultra-short takeoff, according to the quality of aircraft, profile, performance, gives at short notice its huge energy, makes it obtain larger initial velocity and realizes the object of taking off, thereby realize carrier-borneization of various aircrafts.Aircraft carrier generally uses steam catapult now, but its power consumption is large, can only accelerate blimp, can not realize taking off of large and medium-sized aircraft, has seriously limited the development of naval's cause.Owing to being subject to the impact of technology fund etc., it is blank that the carrier-borne jato unit of large and medium-sized aircraft worldwide still belongs to.
Current ejector in the world mainly contains following 3 kinds:
1, steam catapult
Steam catapult is the aircraft launching apparatus on aircraft carrier, takes off for carrier-borne aircraft steam ejection, uses a flush deck as airstrip.While taking off, a steam-powered catapult-launching gear drives aircraft to reach takeoff speed within two seconds.
Heavy airplane wants from carrier-based, must have steam catapult.Before taking off, by holdback steel ring, afterbody is buckled on a firm point, near draw bar aircraft nose wheel hangs in a shuttle, and shuttle is to hook aircraft.Shuttle is the unique part being exposed on flight deck of steam catapult.Under deck before aircraft, have two parallel cylinders, each to 45 meters of the youthful and the elderlys, the piston in cylinder is connected with all shuttles.Steam is exported by the boiler on mother ship carrier, inputs shuttle after supercharging.While taking off, put into high gear, but fastened by holdback.Steam catapult one starts, and the power of aeroengine adds steam pressure, and steel ring is disconnected, and aircraft preshoot reaches 250,000 ms/h of speed per hours in 45 meters of distances.Airplane catapult takes off and departs from after shuttle, and the note pipe of piston nose just falls into pond, in the distance of several meters, pauses, and shuttle is retracted original position, promotes another airplane and takes off.On aircraft carrier, each steam catapult per minute can promote two airplanes and takes off.Conventionally aircraft carrier 4 steam catapults of installing at most.
Steam ejection has two kinds of ejection modes, and one is that front-wheel launches, and, is directly hauled aircraft nose wheel take off while launching by slide block in success of the test in 1964 by United States Navy.Hang tow rope and subtracted tow rope for aircraft without 8-10 people like this, the time of launching shortens, and aircraft safety is good.U.S.'s active service aircraft carrier is all adopted in this way.Only have at present the U.S. to possess the mature technology of producing this steam catapult.
But steam catapult has its intrinsic weak point:
(1) maintenance cost is large, and U-shaped sealing band is changed frequently and very bothered, and requires high to material;
(2) use steam catapult cost large, efficiency is low, and auxiliary facility is many, and system is loaded down with trivial details, and links requires high;
(3) need to consume a large amount of fresh water, the U.S. once considered vapour-condensing equipment for recovering for this reason, cancelled eventually because volume is large and efficiency is low.
2, combustion vapour ejector
Combustion vapour ejector is structurally similar with steam catapult, and the two ends admission port that is only steam has become combustion chamber, and wherein deoxidation compound and oxidizer inject by high pressure, but are controlled, and is to continue to inject.In the time of work, deoxidation compound and oxidizer inject to high combustion chamber pressures, ignition device is reacted deoxidation compound and oxidizer and is produced a large amount of heat in combustion chamber, gas promotes piston acting, due to deoxidation compound and the lasting injection of oxidizer, piston will be under the continuous thrust of gas high-speed cruising, thereby make to take off.After taking off, deoxidation compound and oxidizer stop injecting, and open combustion chamber air port, and the combustion chamber air port of return terminal is closed simultaneously, and piston can stop immediately.Return identical with said process, only little than work of combustion chamber and high pressure injection device.This ejector is controlled by controlling injection deoxidation compound and oxidizer, and advantage is not need fresh water, and work and time of return are short.But shortcoming is many especially, be first that the condition such as high temperature resistant and anti-oxidation of combustion chamber is high, barrel intensity and high temperature resistant require high.The control of injection deoxidation compound and oxidizer requires precisely, data reaction is fast, has certain danger, consumes expensive liquid reducer and oxidizer, and fault rate is high, gets rid of many unfavorable factors such as a large amount of gases pollutions and infrared radiation.Therefore this ejector is in fact just discussed and was analyzed in theory, does not have the record of large-scale practice.
3, the multiple power ejector of spring
The multiple power ejector of spring is to utilize linear electric motors or stored energy mechanism that spring is stretched to energy storage position, utilize stop mechanism to keep energy not discharge, when work, utilize control system to disconnect stop mechanism, spring pulls moving aircraft to accelerate under multiple power, aircraft is lower acceleration of making a concerted effort of self driving engine and ejector, and initialization stroke generally only has 60 meters.But regrettably this ejector can not directly take off airplane catapult, and aircraft must slide one section and just can take off under the thrust of driving engine.And this ejector is that spring is placed in the slideway of opening (internal orifice band lubricating oil) in practical study, object be do not allow ejector when work to around exert an influence, and this large power spring is strict to material requirements, just imagine that so high-performance spring do not change during one's term of military service at aircraft carrier, to material require be how to carve severe, even slideway, its precision also requires very high.This ejector cataplane number of times is not high, because it completes energy storage by stored energy mechanism.More kill be this ejector when initial pulling force very large, can there is the phenomenon of fainting in short-term in aviator, the structural strength of aircraft is also required quite high.And working distal tip pulling force is very little, crucial moment can not accelerated take-off.
