FIELD: weapons. ^ SUBSTANCE: invention pertains to defence equipment of civil aeroplanes and is meant for foiling aircraft hijacking. The device consists of an overview camera. In the passage between rows of seats under the floor of the hull there is a cavity, the floor of the hull over which is made in form of a set of plates, hung on cylindrical hinges with provision for rotation inside the cavity. The plates rest on spring loaded turning supports, installed on arms, mounted in the side bay. The supports are fixed from turning by clamps, fixed on an axis, installed on guide apertures in projections. In the lower part of the cavity there is a mechanism for holding the terrorist, made in the form of horizontal elastic nets, tied to partition walls. The above mentioned axis is joined to a ferromagnetic core of an electromagnet. The actuator coil of the electromagnet is connected to a source of electrical signals. The source provides for retraction of the core of the electromagnet with displacement of the moveable axis, fixing of supports and turning of the plates in the cavity. The holding mechanism allows for trapping the terrorist in the cavity. ^ EFFECT: increased flight safety with simultaneous simplification of the structure of the cabin. ^ 3 dwg |
