Temperature of a structural member is maintained at allowable temperature or less by suppressing heat transfer from a high-temperature duct to the structural member. An insertion sheet according to the present invention is inserted between a flange and a partition panel. The flange is provided on a bleed duct and is fastened to the partition panel. The bleed duct penetrates through a partition wall of an aircraft. The insertion sheet includes first parts and a second part. The first parts are disposed near respective shafts of rivets provided at a plurality of positions of the insertion sheet. The second part extends among the first parts. The first parts bear a load of fastening, and the second part has thermal conductivity lower than thermal conductivity of the first parts.

There is provided a safety device for aircraft, that prevents an explosion of a fuel tank storing aviation fuel, the safety device including: a flame arrester that is arranged near an end of a ventilation passage on an aircraft outer side, as a part of the ventilation passage allowing the inside of the fuel tank and an outside of the aircraft to communicate with each other, to prevent a flame propagation into the fuel tank from the outside of the aircraft through the ventilation passage; and a heat transfer reducing part that is arranged closer to the outside of the aircraft than the flame arrester to prevent heat transfer to the fuel in the fuel tank from the flame.

Safety device for aircraft

A fuel tank that stores fuel to be fed to a fuel supply destination through a pipe, wherein a whole or a portion of a storage fuel contact portion in contact with the fuel within the fuel tank is subjected to surface finishing for imparting hydrophilicity.
