Abstract

The invention relates to a lift-off emitter suitable for various spacecraft boost emission lift-off, and is very suitable for being used on an aircraft carrier, i.e., for lift-off emission of airplanes carried on the aircraft carrier. The lift-off emitter uses a motor to drive a large flywheel for high speed rotation, thus generating inertia force, and is suitable for intermittence working so as to store energy; through necessary facilities like a clutch, belt pulleys, belts and guide rails, the motor with total power of dozens of kilowatts can realize emission lift-off of various spacecrafts or shipboard aircrafts.

Description

Lift-off projector

Technical field the present invention relates to a kind of lift-off feedway of Aeronautics and Astronautics device, is specially adapted to launching of the contained aircraft of aircraft carrier.

The existing carrier-borne aircraft mode of taking off of background technology has old-fashioned cunning more to take off the quantity of (Liaoning warship as China) carrier-borne aircraft, is the principal character representing this warship fight power.And sliding more taking off will take a large amount of valuable shutdown area, so nature will affect fight power.External more new-type taking off vertically, be only limited to aviette, and energy consumption is high.Using more is in the world that steam ejection takes off, and establish the boiler that huge, need a large amount of highly purified fresh water, and ejection frequency can not be too high, and energy consumption is necessarily very high.More advanced country develops electromagnetic launch now, but transmitter current is powerful, and generating set needs powerful and complicated.

Goal of the invention the object of the invention is the deficiency existed for domestic and international carrier-borne aircraft lift-off lift-off technology, and a kind of power consumption of design is low, and floor area is little, and emissivity is strong, transmitting frequency is high and the multiplex lift-off projector of the booster action that can go up to the air to multiple spacecraft.

Technology contents technical scheme of the present invention is: the force of inertia of flywheel large in large-scale friction press, and energy storage effect converts powerful transient dynamics to.This power by power-transfer clutch, belt pulley and guide rail, convert tractive force to, adding recoil spring only needs the electrical motor of tens kilowatts just aircraft can be launched.If the emission angle changing guide rail can also various spacecraft boosting lift-off.Here also to focus on illustratively, with the clutch dog all-in-one-piece driving pulley in power-transfer clutch, it is high especially that this takes turns two side shields, and object impels belt to take turns the winding in good order of last layer one deck at this, the working diameter of belt pulley can be made to increase gradually, pulling in aircraft process and can accelerate gradually.Stored energy mechanism and the principle of the driving pulley that can accelerate gradually of large flywheel high speed rotating are exactly " force of inertia " and " centrifugal inertial force " in mechanics.This theory (non-hydraulic formula) in pressing equipment is generally applied, and has been mature technology.This mechanism should establish after warship and certain hiddenly keep away facility, not allow stranger see right through someone.

Appended drawings 1 is the birds-eye view of lift-off projector, and accompanying drawing 2 is that accompanying drawing 1A-A is to cutaway view.Can be made an abstract after this accompanying drawing 2 reduces accompanying drawing, in two figure, all parts Unified numbers have: main shaft 1, bearing seat 2 and 10, large flywheel 3 and 9, power-transfer clutch 4, clutch dog 5, driving pulley 6, control lever 7, electromagnetic starter 8, electrical motor 11, gear case 12, base 13, guide rail 14, conduction band groove 15, fuselage 16, backing plate 17, traction flat belt 18, abrasionproof dolly 19, guide plate 20, draw bar 21, fuselage towing plate 22, hook of waist band 23, resistance are moved back turnover panel 24, medium-height trestle 25, driven pulley 26, wheel support 27, are connect hitch 28, automatically controlled limiting device 29.

Contrasting accompanying drawing below embodiment the present invention, by describing embodiment, this technology being described in further detail.This technology after the meticulous design of professional and technical personnel, making, installation completion, must move the draw bar 21 of traction belts 18, termination to the stop position of Fig. 2.The anti-intensity of this belt should higher than aircraft weight at least one times.Then aircraft is pushed to guide rail.15, make it exceed resistance move back turnover panel 24 and this turnover panel is opened along dotted line direction, make fuselage return to this resistance to move back on turnover panel 24, on.Draw bar 21 is installed again, this rod rear end has the spring subtracting punching, centre be provided with strong magnet can this bar inhale firmly fuselage towing plate 22, on.(figure position limit do not mark magnet) this towing plate is a frid under shed, so as to draw bar during end 21, can throw off smoothly.Draw bar 21, front end be provided with circular hole by hook of waist band 23, with traction belts 18, link together.For anti-traction belts 18, in distraction procedure with guide rail 14, produce and wear and tear, an ad hoc abrasionproof dolly (4 take turns) 19 and with guide plate 20, abrasionproof dolly 19, arrive at a station after have an elastic hitch 28 that connects to go to the station to meet somebody.For ensureing that driving pulley 6, in good time stall are provided with automatically controlled limiting device 29 in conduction band groove 15, position that end is suitable, are used for controlling clutch dog 5, in good time disengagement.Just can start after above-mentioned operation is complete, it should be noted that especially, regardless of between test session or used life, must safety guard be installed to the high-speed rotary part in system.Various starting switch should be drawn outside scene, answers Long-distance Control especially in process of the test.Traction belts 18, also can use chain, rope replaces.

This technology of technique effect proves due technique effect below by way of theory calculate: set electrical motor as 60 to 80 kilowatts, flywheel diameter is 1 meter, weight 1 ton, rotating speed 600 revs/min of centnifugal forces are: square being multiplied by quality and approximating 1972 tons of meter per seconds divided by radius of speed.With large-tonnage engine installation like this, launch the opportunity of combat only having tens tons be placed on the guide rail of slope, do not set up problem, but also can make our opportunity of combat bullet-loading capacity, oil reserve farthest increases, and greatly improves its combat capabilities.
