Description
Technical field
The present invention relates to a kind of steam catapult, particularly a kind of stream catapult for aircraft carrier based airplane.
Background technology
At present, the stream catapult for aircraft carrier based airplane technology is to the fixed-wing carrier-borne aircraft, and taking off from aircraft carrier to rely on ejector to obtain an initial acceleration, thereby is issued to enough takeoff speeds in the limited condition of ground run distance.Though this technology is the steam catapult of Englishman's invention, up to now, have only the U.S. to produce and be used for ejector under battle conditions, what the used steam catapult of the U.S. used is the cylinder opening technology.This technological deficiency is: 1, solving on the powerful tension that will bear in the cylinder opening place, pay qualitative cost; 2, in that to solve the cylinder opening left-hand thread technical, refer to that " sealing chain " will bear huge steam pressure and wear and tear with chain, very easily be out of shape and damage that thousands of sorties need repairing and change parts, maintenance is big.What its reason was that the used aircraft carrier-based aircraft ejector of the U.S. adopts is the opening cylinder, and the barrel of its opening symmetry just needs corresponding thickening, otherwise under the high pressure of steam, opening part can increase, and causes poorly sealed closely, and steam rushes down outward.In fact, except that symmetrical barrel thickening, the opening cylinder outer wall also will be reinforced; Owing to adopted the opening cylinder, maximum trouble is the sealing cutter of the piston sealing problem during through opening, in fact; It is different that ejector piston and pot type piston do not have, but the piston on the ejector is longer, and main purpose is: 1, strengthen its stability; 2, be because the sealing cutter must be extremely thin, and thrust is bigger, so have only the sealing of increasing cutter width just can deal with problems; And the width of sealing cutter has increased, and piston also needs corresponding increase length.Drawing traction element is through sealing and external component bonded assembly, and the maximum problem of ejector is the junction of sealing cutter and U type sealing band, because the sealing cutter must back down U type sealing band through out-of-date at interface; Be bound to sealing cutter seam after backing down and steam rushes down outward; If the sealing force of U type sealing band is very big, sealing effectiveness is fine certainly, but the resistance that seals cutter also can be very big; The wearing and tearing of U type sealing band are also just fast more; So seal in order to solve well, running resistance and U type sealing band wear problem, the U.S. takes the lead in having adopted " high pressure fine flowing water packing technique " to solve this problem; Rush down outward though also have some steam, the friction drag and the U type sealing band abrasion factor of sealing cutter reduce greatly.But, it is also imperfect, and U type sealing band wearing and tearing remain the maximum hidden danger of puzzlement ejector, and daily attention and maintenance be suitable trouble all, though updating material always and employing new technology, so far still can not be satisfactory, U.S. army is very big to this suggestion.
All be to utilize the slide block on the catapult track to launch away aircraft at a high speed when carrier-borne aircraft takes off; And according to the bind mode of carrier-borne aircraft and slide block, ejection mode can be divided into the tow rope formula and front-wheel towed, wherein tow rope formula ejection mode is the old mode that the fifties is brought into use; Need 8-10 name deck staff to hang over aircraft on the slide block rope with the steel tow rope earlier; Use an index trigger bar to captive joint its afterbody with the ejector rear end again, when launching, the power of deciding broken on the index trigger bar of the slide block of preshoot is broken bolt with sudden force; Towing aircraft quickens rapidly along track; Accelerate to straight takeoff speed to aircraft in track ends and cast the deck aside, tow rope drags from aircraft, and slide block returns the ejector starting point and prepares to work next time.Another kind of mode is that front-wheel traction ejection mode is United States Navy's success of the test in 1964; The front-wheel support of carrier-borne aircraft is equipped with haulage rod; Front-wheel just directly hangs on the slide block; When launching, directly haul aircraft nose wheel by slide block and quicken to take off, so just hang tow rope and picked up tow rope without 8-10 name deck staff.This programme time of launching shortens, and the direction safety of aircraft is good, easy and simple to handle; U.S. army's active service atomic aircraft all adopts this mode of taking off; But because the effect of power is direct reinforcing, do not have energy snubber, the nose undercarriage of carrier-borne aircraft need be done customized design and reinforce.
