Abstract
The present invention proposes a kind of portable directional explosion-proof apparatus structure in civil aircraft main cabin, including spherical can body, strengthens side-panel, wherein spherical can body is interior, domestic and abroad three-decker.Spherical structure main body both sides are respectively there are one hangers handle, convenient for the locking of the movement of orienting device, rotation and structure.It is of the invention with traditional explosion-protection equipment principle the difference lies in：The directional explosion-proof device is mainly that the shock wave that the explosion of certain equivalent generates is oriented to outside aircraft passenger compartment, and energy is allowed to discharge, ensures passenger plane and the safety of occupant to greatest extent.Present invention employs quick-release type locking structure, the corresponding groove of design at the minimum risk bomb position that need to be only specified in aircraft passenger compartment just can be by portable directional explosion-proof device quick lock at specified minimum risk bomb position.And the device does not need to design additional hole and goes to be put into explosive, and hole is avoided to become the weak spot of device so that the portable directional explosion-proof apparatus structure of the present invention is simple, explosion-proof energy is strong, easy to operate.
Description
Technical field
The present invention relates to the safe explosion-proof protection technology field of the aircrafts such as civil aircraft more particularly to a kind of civil aircraft main cabins
Portable directional explosion-proof device.
Background technology
In recent years, increasingly serious with international situation, the attack of terrorism has the sternness spread rapidly in the world to become
Gesture, all the time terrorist can choose the stream of people concentrate, it is bad sue and labour, the terror consequence such as lethality is big, social influence is extensive
Place implements to attack, to achieve the purpose that frighten and cause crowd panic.Commercial aircraft meets all conditions above, is that terror is attacked
The primary selection hit, and improvised explosive devices cause the event of aircraft accident to happen occasionally.Although bomb detection technology is not
Disconnected development, but in the case of huge flow of the people and car loading, it is difficult to ensure that perfectly safe.Bomb is it is possible to by a variety of
Approach is brought on aircraft：As the hand-baggage of boarding passenger, crew, canteen dining car, maintenance and repair personnel, registered luggage,
Cargo and airmail etc..For current airplane design, if do not taken special protection and explosion precaution, small amount bomb
Explosion can all trigger chain reaction, lead to the major disaster of fatal crass.Such as the Lockerbie airplane crash of 1988 is happened at, it is beautiful
State passenger plane B747 has just taken off soon, and by investigation, about 280 to 400 grams slurry explosives are detonated in fore hold, and aircraft is in the air
Explosion is disintegrated.259 passenger and crews and 11, ground Lockerbie resident on flight is eventually led to die an unnatural death.
In the case, it is proposed to resisting the ability sabotaged in the flight safety of aircarrier aircraft and flight course
Higher requirement.International Civil Aviation Organization (ICAO) issued International Civil Aviation pact attachment 8 the 97th on March 12nd, 1997
Amendment, it is proposed that civil aircraft considers minimum risk bomb position (LRBL) in design, and being found band for placement boards a plane
Bomb.
In view of the above problems, the external technologies such as bomb detection technology, cargo hold Explosionproof container and the blast resistance construction carried out
Research work.The Explosionproof container structure wherein invented is applied to aircraft cargo bay more, though also have applied to aircraft passenger compartment, knot
