The specific embodiment:
Technical scheme of the present invention realizes in the following manner: as depicted in figs. 1 and 2, its structure by engine 1, power-transfer clutch, flywheel 4, transmission shaft 8, traction winch 7 and put rope winch 9 form, wherein traction winch 7 and flywheel 4 are arranged on transmission shaft 8, flywheel 4 is fixed together with transmission shaft 8, traction winch 7 is connected with transmission shaft 8 by bearing, between flywheel 4 and traction winch 7, flywheel clutch 5 is set, transmission shaft supports fixing by bearing seat 3, the end of transmission shaft 8 is connected with engine 1 by electric motor clutch 2.
Flywheel 4 is in traction winch 7 bilateral symmetry settings.Engine 1 is symmetrical arranged at transmission shaft 8 two ends.
Put rope winch 9 steel rope be connected with hauling hook 10, hauling hook 12 with by steel rope, be connected with traction winch.
On hauling hook 12, be provided with pulley, two carrier-based aircraft ejector traction winches 7 use a hauling rope 6, and the centre of hauling rope 6 is connected with the pulley on hauling hook 12.
Engine 1 refers to electrical motor, diesel engine, spark ignition engine, steam turbine, turbo-machine and HM Hydraulic Motor.
Put rope winch 9 by putting rope winch clutch 10 and putting the winch motor 11 of restricting and be connected.
The type selecting of engine is to determine according to the tonnage of aircraft carrier or classification, if nuclear aircraft carrier, owing to carrying steam boiler, can be used steam engine or steam turbine that power is provided.If aircraft carrier powered by conventional energy can use electrical motor, turbo-machine, HM Hydraulic Motor or diesel engine to do power.Shown in accompanying drawing, the power take-off shaft of engine is connected to the work of getting final product with engine power-transfer clutch.
Ejector of the present invention can have multiple combination, such as can using an engine, traction winch drives, also can use symmetrical connection of two engines to drive, can also use in parallel use of traction winch of the double dynamical machine of two covers that large traction is provided, for launching early warning plane or other heavy bombers.Constructional drawing as shown in Figure 2.
Principle of work of the present invention is as follows: the engine of usining is equipped with flywheel energy storage as propulsion source, by the flywheel amount of holding, under the cooperation of power-transfer clutch, the energy aggregation of the energy of flywheel and engine is got up at short notice for opportunity of combat provides maximum tractive force, opportunity of combat slides in 5-10 rice, the whole adhesives of power-transfer clutch, engine is with regard to full load carrying out full speed traction to opportunity of combat, in addition under the reducing effect of traction winch, for opportunity of combat provides extra acceleration, realize the short range catapult-assisted take-off of opportunity of combat; Specifically launch step as follows:
Engine provides turning effort, by electric motor clutch and transmission shaft, drives flywheel to rotate, and when flywheel rotates, reaches after certain rotating speed, stand-by;
The hauling rope end of traction winch connects hauling hook, and hauling hook is connected and awaits orders with carrier-borne aircraft front-wheel by putting rope traction to the carrier-borne aircraft takeoff point of rope winch;
When dispatcher assigns after takeoff order, flywheel clutch adhesive between flywheel and traction winch, engine continues full-load operation, traction winch is connected driving traction winch rapidly and rotates with flywheel by flywheel clutch, the hauling hook of traction end pulls opportunity of combat to accelerate to move ahead, because traction winch is at the rotation initial stage, hauling rope is that minor diameter is wound around in the winding of traction winch axial region, haulage speed is slow, but tractive force is large, along with being wound around the increase of the number of turns, cooling diameter is increasing, thereby haulage speed is more and more faster, before arriving ship side, opportunity of combat has reached takeoff speed, at this moment hauling hook is separated, opportunity of combat lift-off,
Put rope winch and be by putting rope clutch and putting the motor of restricting and be connected, when traction winch traction opportunity of combat starts to slide, putting rope winch clutch discharges, the steel rope of putting rope winch is pulled always and is pulled to runway terminal, when opportunity of combat flies away from behind deck, put the power-transfer clutch adhesive of rope winch, flywheel clutch discharges, traction winch is no longer stressed, put rope winch the rotator inertia of traction winch is carried out to damping, traction winch stall, then hauling hook is put rope winch and is retracted runway starting point, put rope winch clutch and discharge standby, second opportunity of combat enters takeoff point and is connected the next takeoff order of wait with hauling hook.
Adopt electrical motor that power is provided, the work of each power-transfer clutch is all that relay or computer program are controlled automatically, controls very simple and reliable.Such as, at the starting point and the terminal that launch runway, limit relay is set respectively, when opportunity of combat is taken off, program starts, and puts rope winch clutch and discharges, flywheel clutch adhesive, when hauling hook traction opportunity of combat slides into the runway end on runway, the limit relay of runway terminal starts, and flywheel clutch discharges, and puts the adhesive of rope winch clutch, the inertia that stops traction winch to produce, it is standby that traction hauling hook is got back to runway starting point simultaneously.Adopting the advantage of electrical motor is that degree of automation is high, and volume is little, safety good, and electric energy provides by the electric power system of naval vessels.
If adopting diesel engine, automotive gas turbine is example, when opportunity of combat is taken off, program starts throttle and automatically strengthens, and puts rope winch clutch and discharges, flywheel clutch adhesive, hauling hook traction opportunity of combat slides into runway terminal, limit relay starts, and flywheel clutch discharges, and puts the adhesive of rope winch clutch, the inertia that stops traction winch to produce, it is standby that traction hauling hook is got back to runway starting point simultaneously.Hauling hook is capable when the terminal, and flywheel is accelerated to maximum speed simultaneously, and throttle discharges automatically, and diesel engine is treated speed work, and flywheel is rotated further.The intermittent use of diesel oil can reduce consumption of fuel, the service life of extension device.
The designing requirement of the power of engine, single-power machine should can accelerate to takeoff speed by opportunity of combat in second at 5-15, the accumulation of energy of a flywheel should at least equal the energy output of an engine within the unit time, adopt so double dynamical machine and free wheels setting, the amount of redundancy that just has three engines, can guarantee that the full speed of opportunity of combat is launched safely completely.If to launching of early warning plane or bomber, except selecting supporting engine and flywheel, can also the above device parallel connection of two covers use, as shown in Figure 2.Can also on power-transfer clutch, configure if necessary toric transmission to adapt to the catapult-assisted take-off of different aircrafts.
If device of the present invention is designed to miniaturization, can also launching for unmanned plane.
