HOUSING OF PROTECTIVE BOARD INFORMATION STORAGE Russian patent published in 2017 - IPC G12B17/08 G12B17/06 B64C1/38 

FIELD: mechanical engineering.

SUBSTANCE: invention relevant to means for protection of board storages of flight information (SFI) of such aircraft as airplanes and helicopters against exposure to such external destroying factors as: mechanical shocks, overloads, vibration, stationary pressures, as well as factors of fire and corrosive liquids. Housing of the protective board information storage is intended for protection against exposure to such external destroying factors as: mechanical shocks, overloads, vibration, stationary pressures, as well as factors of fire and corrosive liquids and consisting of external housing made of high-temperature alloy, which is provided with perforated drainage holes and on the outside coated with layer of heat-insulation bimorph heat-shielding inter-layer; and of internal shockproof container made of high-temperature corrosion-proof alloy, which from above is coated with layer of dry elastic porous-fibrous material of low thermal conductivity, which functions as thermal insulation and coated from above with metal foil, wherein that inner surface of external housing is coated with thermoplastic polymer film, internal airtight container is vacuumed, and protected object is held in the center of container with the aid of four and more conical springs, which tops are directed to container housing. Ice layer is placed between internal container and external housing of container. Intermediate mesh housing provided with porous steam-proof fabric that is covered with nap, for example, fur, is placed there. Position of external housing, intermediate mesh housing and internal container relative to each other is fixed with the aid of inserts made of dry porous elastic heat-insulating and incombustible material coated with water-proof heat-resistant film.

EFFECT: device for protection of aircraft board SFI against exposure to external destroying mechanical factors, which provides protection of 100 % against corrosive liquids and at least 2-fold increase of time of exposure to high temperatures.
