Energy gathering and pressure relieving civil aircraft passenger cabin directional explosion-proof device

Abstract

The invention provides an energy gathering and pressure relieving civil aircraft passenger cabin directional explosion-proof device comprising a cylindrical tank main body 1, a front end conical energy gathering and pressure relieving steel thin plate 2, a rear end face edge straightening panel 3, two installation bases 4 and a three-groove type rear end cover 5. The energy gathering and pressurerelieving directional explosion-proof device is used in cooperation with a pressure relieving opening at the least risk bomb location of an aircraft structure, and by means of the inner conical structure, explosive shock waves can be guided to the outer portion of an aircraft passenger cabin to be released to the maximum extent, and safety of structures and passengers in the cabin is ensured. Thedevice is connected with an aircraft floor seat groove through the installation bases, placing and closing of explosive are facilitated through the three-groove type locking structure, and the energygathering and pressure relieving civil aircraft passenger cabin directional explosion-proof device has the beneficial effects of being easy to detach, convenient to operate and capable of being installed at multiple positions.

Description

[0001] The invention relates to the fields of civil aircraft survivability, safety explosion-proof and structural design, in particular to an energy-gathering and pressure-relieving directional explosion-proof device for a passenger cabin of a civil aircraft. Background technique [0002] The explosion of explosives inside the cabin during the flight of a civil aircraft will have a huge impact on flight safety. For example, in the Lockerbie air crash in 1988, terrorists carried nearly 400 grams of plastic explosives, which detonated shortly after the plane took off. The plane exploded and disintegrated immediately in mid-air, killing 270 passengers, maintenance and ground personnel. Since then, although all countries have strengthened the security checks at airports, due to various factors and negligence, there have been many cases where terrorists successfully boarded planes with explosives. For example, on December 25, 2009, a Nigerian youth boarded a Delta Airlines flight c...
