DEVICE FOR DISARMING TERRORISTS IN CIVIL AEROPLANES Russian patent published in 2008 - IPC B64D45/00 

FIELD: aircraft.

SUBSTANCE: invention pertains to defence equipment of civil aeroplanes and is meant for foiling aircraft hijacking. The device consists of a cavity with a bottom, located in the passage of the cabin between rows of seats under the floor of the hull. The floor in the zone of the passage is made in the form of an elastically joined pair of plates, installed in guides with provision for displacement using springs. The projections at the bottom provides for hardness of the floor. The plates are joined over through blocks by ropes with an electromagnetic core, installed at the bottom of the cavity. Tensoresistors are glued to the plates and connected to the bridge measuring circuit. At the edges of the plates there are contact guides. The actuating coils and contact guides are connected to sources pulsed and smoothly variable electrical signals. The first source provides for separation of plates with seizure of the terrorist's legs, while the second passes electrical current of given amplitude through the body of the terrorist.

EFFECT: increased flight safety with simultaneous simplification of the structure of the cabin.
