Description
Technical field
The aircraft steam catapult that the present invention relates to use on aircraft carrier, particularly a kind of suit twin-tub head end group valve steam catapult.
Background technology
Aircraft wants from carrier-based, the thrust that must produce by steam catapult.Steam catapult is Englishman's invention, but, up to now, only having American to produce can be for steam catapult under battle conditions, the main body of steam catapult is a large-scale reciprocating cylinder, steam energy is converted into kinetic energy and launches, and high temperature and high pressure steam is produced by the propelling boiler on naval vessel, be stored in pressure accumulation tank, the input of the steam in pressure accumulation tank and pressure regulation are to be controlled by valve.The steam catapult of United States aircraft carrier active service adopts split cylinder, and cylinder interior has individual piston, and piston need to be connected with slide block through cylinder wall, and slide block connects the alighting gear of aircraft by hauling hook.Therefore, split cylinder is from there being from the beginning to the end bar seam.This seam is sealing usually, in the time of piston process, opens, and piston is then shut in the past.Split cylinder has two large problems;
The firstth, the problem of distortion after cylinder itself is heated, open cylinder will be born the pressure that high temperature and high pressure steam produces, owing to there being opening on cylinder wall.The mechanical characteristic of open cylinder is very poor, accomplish that indeformable is quite difficult.Once cylinder distortion, cylinder straightness accuracy declines, and Hua Kuai Longitude is out-of-date, can and level and smooth track between beat, cylinder and track both sides serious wear.
The secondth, be difficult to sealing, open cylinder sealing is crucial, the sealing property of this position is very important, is related to and launches safety.The rubber tape that is arranged on cylinder openings both sides that old-fashioned ejector adopts forms ' slide fastener, formula sealing, the ejector of active service utilizes a U-shaped sealing band to insert in the opening of cylinder, no matter be which kind of method, maintenance cost is large, U-shaped sealing band is changed frequently and is very bothered, to material, require high, although it is no problem meeting the needs of taking off, but the seal degree reaching as steam engine cylinder is impossible, while therefore launching at every turn, one high temperature white smoke is filled the air in capital below deck, this is the high temperature of revealing, high pressure steam, not only consume a large amount of fresh water but also wasted a lot of energy.The greatest problem of steam catapult is; The lifting that speed and strength cannot be gained simultaneously, cannot realize optimized matching and do manual work, and opportunity of combat is taken off slow, and just because of there being the problems referred to above, United States Navy is actively developing failure-free steam catapult more, but also not success at present.
Summary of the invention
The object of this invention is to provide a kind of suit twin-tub head end group valve steam catapult, it utilizes the work of high temperature and high pressure steam instantaneous expansion principle, and while launching, force of explosion is very large, reaches to allow the object of aircraft moment lift-off.
For achieving the above object, the present invention is by the following technical solutions:
A suit twin-tub head end group valve steam catapult, comprises Steam Recovery chamber, left annular vapour storage tank, right annular vapour storage tank, piston, output shaft, end inner casing and end housing; It is characterized in that: described left and right annular vapour storage tank, by porous support ring, cylinder in tank shell, left and right cylinder liner, cylinder liner strut bar, tank, left and right cylinder head alive and partition ring form, left and right annular vapour storage tank is connected to form into ejection chamber with end inner casing, end housing, piston and left and right energy disperser and output shaft are housed in ejection chamber, and output shaft is loaded on center, piston both sides and protrudes from left and right energy disperser, two side ends inner casing, end housing.
Described left and right energy disperser is fixed on two side ends inner casing, in end inner casing and end housing, vapor cock is housed, vapor cock is comprised of steam discharge valve casing and steam discharge spool, steam discharge valve casing and steam discharge spool are provided with the applicable a plurality of exhaust holes of distance equally, and steam discharge spool Longitude grid leaf is connected by electromagnetic valve bi-directional drive with mandrel.Described end housing end is connected with annular electro magnet valve, is provided with annular and closes coil in annular electro magnet valve, closes spring, annular admission coil and annular core.Many pull bars of Huan shape Tie Xin Longitude are inwardly affixed through end housing, end inner casing and left and right cylinder head alive.
Described output shaft is comprised of axle core, insulating collar, large insulating collar, becket, hold-down nut, output shaft and the Pluse signal sensor moving contact that is contained in end housing end.The present invention adopts totally-enclosed cylinder air-tightness good, and compact conformation, can two-wayly launch.
