Technical field

The invention belongs to Aircraft Ejection Seat field of structural design, and in particular to a kind of protective device of airplane catapult and guarantor Maintaining method.

Background technique

Ejection escape is aircraft when flight failure occurs, and pilot is rescued by one kind that ejector seat is detached from breakdown plane Raw mode.At the critical moment, pilot starts the demolition set of ejector seat, and ejector seat is together with pilot's ejection to sky In, then parachute jumping is separated with seat.In ejection process, the aerodynamic loading that is generated due to high-speed motion to the extruding in pilot thoracic cavity with And explosion residue object never protects the injury of pilot's body well.In case of yaw rotation, will lead to The safeguard procedures of the anti-Windblasts such as the head rest umbrella case and shelves arm device of seat are unable to get good implementation.

Summary of the invention

A kind of protective device and guard method for being designed to provide airplane catapult of the application, is mounted on the ejection of aircraft On seat, aerodynamic loading can not be protected when occurring and yawing rotation and cause to pilot by solving current Aircraft Ejection Seat Such issues that injury, effectively stops blast impulse simultaneously also by baffle area is increased, and the shock of residual foreign improves structure Reliability and comfort.

A kind of protective device of airplane catapult, is mounted on the ejector seat of aircraft, which is characterized in that the protective device packet Include sliding rail and baffle；The sliding rail is two symmetrical arcuate structures, is separately fixed at the two sides of ejector seat, the baffle Be two pieces, be symmetrically distributed in ejector seat both sides, the inside of baffle be equipped with the matched sliding slot of sliding rail and handle, on each sliding rail One baffle of corresponding installation, the baffle are similarly arc plate, and the front side end of baffle is equipped with buckle structure, the buckle structure Docking and the igniter of ejector seat link.

The detonation route of the ejector seat igniter is embedded on baffle, and the voltage flame proof switch that rises of igniter is split two The front side end of a baffle.

The rear side end of the baffle is equipped with connection structure, which is linked as one for the rear side end of two baffles Body, the connection structure are equipped with explosion lock, and by explosion lock control, the voltage flame proof switch that rises for the lock that explodes is located at gear for the failure of the connection structure On the handle of plate.

The application also provides a kind of guard method of airplane catapult, it is characterised in that include the following contents, 1) in aircraft Ejector seat is equipped with a protective device, which includes sliding rail and baffle；The sliding rail is two symmetrical arcs Structure is separately fixed at the two sides of ejector seat, and the baffle is two pieces, is symmetrically distributed in ejector seat both sides, baffle Inside be equipped with the matched sliding slot of sliding rail and handle, one baffle of corresponding installation, the baffle are similarly arc panel on each sliding rail Shape, the front side end of baffle are equipped with buckle structure, and the docking of the buckle structure and the igniter of ejector seat link, baffle Rear side end is equipped with connection structure, which is linked together the rear side end of two baffles, which is equipped with Explosion lock, by explosion lock control, the voltage flame proof switch that rises for the lock that explodes is located on the handle of baffle for the failure of the connection structure；2) non-ejection When state, the rear side end of above-mentioned baffle is connected structure and is fixed as one, and baffle is located at the rear side of ejector seat；3) bullet is needed When penetrating, pilot's both hands hold the handle of baffle respectively and open explosion lock-switch, by the connection structure solution of end on rear side of baffle Lock disconnects；4) pilot continues through handle pulling two side baffles to front and closes up, and the buckle structure of end comes into force on front side of baffle And two side baffles are fixed, two side baffles surround the precordial locations of protection pilot, while the igniter of linked ejection seat, bullet Penetrate seat starting ejection.

The beneficial effects of the present application are as follows: 1) of the invention airplane catapult protective device, it is simple and reliable for structure, it is easy to grasp Make, it is highly-safe, it can be used for ejector seat security system, the aerodynamic loading for preventing high-speed motion from generating using chest baffle is to winged Injury of the extruding and explosion residue object in office staff thoracic cavity to pilot's body.2) after baffle is placed in the side of ejector seat when flight Portion, and fixed with explosion lock, save the space of driver's cabin.3) hand for playing voltage flame proof switch and baffle being set of the explosion lock of fixed baffle On handle, the front side end of the baffle of the ejection switch setting of ejector seat completes pilot first while handling crisis Protection to oneself.
