Abstract

A track block chain shipboard aircraft catapult is a mechanical catapult. The catapult is simple in manufacturing process, and can use the manufacturing technology of high speed railway for reference, and does not have technical bottleneck. The technical scheme is that two pairs of annular rails (4,5) and an electric power contact system are laid in a vertical direction under an aircraft carrier flight deck (6), surrounding a hangar and other cabins, shapes of the annular rails are similar to a running track. An annular block chain formed by a plurality of tackles which are connected end to end operates on the rails. The tackles are connected by connecting rods and cables. The tackles are divided into power tackles, driving tackles, and catapult and traction tackles according to functions. The total mass of a system motion part is larger than 60 tons, and running speed of the block chain is 100 m/s. When an operation handle (1) pulls a sliding plate (3) backward to make the hook of a sliding shuttle (2) fall into the track, the hook would hook a catapult traction rod on the tackle, and catapult starts. On the trail end of the track, a fixed projection (7) presses the traction rod to complete unhooking, and catapult ends.

Description

Track sliding blockchain carrier-based aircraft ejector

Technical field

The present invention relates to a kind of carrier-based aircraft ejector, particularly relate to a kind of mechanical type carrier-based aircraft ejector.

Background technology

Present stage, ejector mainly contained two kinds, steam catapult and Electromagnetical ejector, the mainly steam catapult used at present.Steam catapult is a complicated system engineering, except the equipment of ejector itself, also has many affiliated facilities such as desalting plant, reservoir, high-pressure hydraulic pump, boiler, heating arrangement.According to open source information display, active service steam catapult total weight, close to 500 tons, on average launches at every turn and consumes nearly 700 kg of vapor.Fresh water is of great value concerning aircraft carrier, and sea water desalination needs to consume the energy.In addition also to there is maintenance cost large for steam catapult, and U-shaped sealing band is changed frequently and the very shortcoming such as trouble.Electromagnetical ejector has many good qualities compared with steam catapult, but also there are some shortcomings, and one consumes a large amount of electric energy when being and launching, and for aircraft carrier powered by conventional energy, generating capacity is limited, cannot meet the needs of ejector, can only be contained on nuclear aircraft carrier.Two is that electromagnetic radiation is serious, causes severe jamming, must carry out electromagnetic protection to electronic machine on warship.

Except above shortcoming, be that steam catapult or Electromagnetical ejector all exist a common drawback: manufacturing technology exists bottleneck.The storage tank of steam ereisma, open cylinder and metal sealing bar require high to material, processing technology.The superpower cycloconvertor of Electromagnetical ejector has high technology content.Most countries is unable overcomes these technical difficulties, so only have the aircraft carrier of a few countries to install ejector at present in the world, and these ejectors originate from the U.S. mostly.

Summary of the invention

In order to overcome the manufacture difficulty of existing ejector, the invention provides a kind of fabrication scheme of mechanical ejection device.Simply there is not technical bottleneck in this ejector manufacturing process.There is the advantage that volume is little, lightweight, do not consume fresh water, do not consume a large amount of electric energy compared with existing ejector.

The present invention adopts technical scheme to be: vertical direction below the flight deck (in Fig. 1 6) of aircraft carrier, two pairs of ring rail are laid around hangarage and other cabin, each a pair of inner and outer ring (in Fig. 14,5), shape as track and field runway, only it is not horizontal arrangement but vertically arranges.Rail runs row annular block chain from beginning to end (shown in Fig. 2), pipe link (in Fig. 2 10) is adopted to couple together between coaster, there is a coaster that draw bar (in Fig. 2 15) is housed in chain, when on deck launch shuttle (in Fig. 1 2) hook draw bar time, block chain relies on the inertia towing aircraft of itself to slide forward at a high speed.

Hook: ejecting hook is that hook shielding slide plate (3) by being contained in ejection orbit head end controls, and when 3 are pulled back into certain position by operating handle (1), hook falls in track, and the draw bar (15) of high-speed cruising will be tangled by hook, launches beginning.Break off relations: unhook is that unhook shielding projection (7) by being contained in ejection orbit end realizes, and when draw bar drives hook to run to track end, draw bar is depressed by projection 7 and departed from hook, launches end.

Ejector principal parameter: motion parts total mass is greater than 60 tons, and driving power is greater than 1200kw, block chain total length about 200 meters, catapulting distance 80 meters, block chain running velocity 100 meter per second.Calculate by carrier-borne aircraft takeoff speed 80 meter per second, it is burnt that ejector exports energy 108,000,000, between the steam catapult and Electromagnetical ejector of the U.S..Adopt the driving power of 1200kw, often launching the heavy aircraft of 30 tons, a frame needs 80 second time makeup energy, if dislike time length to increase driving power.

Launch shuttle to return: scheme one: make a remote control electric tractor truck travelled along chute, after aircraft ejects, head end operating personal presses tractor truck forwarding button, tractor truck drives towards end automatically, after arriving end, shuttle hook first lifts and locks (making hook leave eject chute) by end effector personnel, and then is suspended on tractor truck by shuttle, presses return push-button and shuttle is towed back to head end.Scheme two: automatically departs from chute after shuttle enters buffer zone and drop into recycling network, concentratedly sends head end back to, and head end remains two shuttles in chute, can avoid like this because of the loading shuttle delay time.

Detailed description of the invention

Manufacturing technology can with reference to high ferro correlation technique, and just size reduces.

Pulley structure: each coaster two axles, every root axle installs two pairs of wheels, and each a pair of inside and outside rail (in Fig. 2 17,18), wheel profile is tapered tread.Installing the object of two pairs of wheels is wheels corresponding to inside and outside rail, produces friction when preventing coaster from becoming rail because wheel changes rotation direction.Wheel divides two kinds, and one is sliding wheel, installs bearing between wheel and axle; Two is drive wheels, fixing between wheel and axle.

Type of drive: in order to simplified apparatus, first considers three-phase alternating-current powered mode, and lay power contacts net (figure A-in A 8) in orbit, contact system is two-phase, and other one makes conductor with rail, and supply transformer and drive motor winding connection are as shown in Figure 4.Coaster divides several types, car is installed plane draw bar (in Fig. 2 15) be extension pulley, install pantograph (in Fig. 2 11) be powered coaster, install electrical motor (in Fig. 2 19) for drive coaster.Driving coaster occupies the majority, and powered coaster occupies the minority, and extension pulley only needs one.Unpowered coaster 8 wheels are sliding wheel.Driving coaster is different, and every root axle has pair of driving wheels (in Fig. 2 18) and sliding wheel (in Fig. 2 17), respectively corresponding interior rail and outer rail.

Still can normally use after ensureing the rainy day or enabling fire appliance, electrical equipment need by outdoor production-release design.Except extension pulley, other coaster preferably installs protective cover; In order to simplify driving pulley structure, with a direct motor drive two axles, electrical motor is longitudinally arranged, two outputting power.The differential problem of two axles when entering arc section about coaster, can be solved by the tread profile changing arc section rail; Be connected with other coaster with spring respectively before and after extension pulley, front end is for launching recoil spring (in Fig. 2 16), and rear end is block chain tensioning spring (in Fig. 2 13); Conveniently keep in repair, adopt bolt to be fixed on warship body by rail, and non-solder; In order to reduce noise, between rail and warship body, install yielding rubber pad additional.Driving power can be estimated with reference to high ferro dynamical parameter 20kw/ ton.

Reference scheme one: coaster quantity 68, wherein extension pulley 1,3, powered coaster, driving 64, coaster.Coaster length 1.5 meters, pipe link length 1.44 meters.Three-phase alternating-current powered, line voltage 3.0kv.Each drives coaster to install a 20kw three phase asynchronous motor.In order to avoid using high-voltage high-power motor when not using step-down transformer, driving coaster being divided into 8 groups, often organizing 8, the stator winding of 8 motors is connected in series.Motor needs customized design, and the turn-to-turn insulation of winding presses 0.4kv design, and 3.0kv design is pressed in alternate and ground insulation.Each coaster conducts oneself with dignity 700 kilograms, and every platform motor weighs about 200 kilograms, adds upper connecting rod, cable etc., motion parts total mass about 60 tons, driving power 1280kw.

Reference scheme two: coaster quantity 26, wherein extension pulley 1, driving 24, coaster, counterweight pulley 1, each heavy 2.3 tons (driving coaster containing motor weight).Long 1.5 meters (more short better) of coaster, each drives coaster to install a 55kw motor.Three-phase alternating-current powered, line voltage 3.0kv.Drive coaster to be divided into 3 groups, often organize 8, often in group, have one pantograph is installed.Electrical machine insulation design is identical with scheme one with winding on-link mode (OLM).Be connected with cable (in Fig. 6 25,26) with cable wire between each coaster, rope length about 6 meters.Some roller supporting cable wires (in Fig. 5 24) are installed in the inner side of track segmental arc.Cable is through in the middle of spring (figure E-in E 26), and when crossing curved, spring and roller contact, prevent cable from wearing and tearing.System motion part total mass about 60 tons, driving power 1320kw.

Reference scheme three: adopt phase asynchronous linear motor to drive (parameter of electric machine needs specific design), install drive motor stator modules (in Fig. 7 27) in the inner side of track linear portion, mover module (in Fig. 8 28) installed by driving coaster.Compared with the first two scheme, program structure is exquisite, equipment is simple, without the need to contact system and pantograph, easy to maintenance, reliable.Because mover module is writing board shape, effectively can reduce rail section and amass; Because wheels all on coaster are all sliding wheels, there is not the differential problem of segment of curve, without the need to customized design rail tread.Shortcoming: magnetic field of stator end region distortion causes that loss is large, efficiency is low; Stationary part does not participate in energy storage, increases some additional weights; Improve linear motor performance to reduce air gap, to the flatness of track and the requirement on machining accuracy of coaster higher, thus give manufacture and installation bring certain trouble.
