Abstract: In a structure for mounting a radar, a cross linking member vertically connects two width-across members aligned in a front-to-rear direction of a vehicle. A fixing member is fixed to the cross linking member. The fixing member includes a fixing part fixed to the cross linking member, a supporting part that supports a radar device, a deformable part. The deformable part has a shape connecting the fixing part and the supporting part and bends and deforms to absorb shock when an external force is input into the radar device.

Abstract: 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.

Abstract: A water-inflow prevention device is provided by installing a closing lid 6 for blocking a duct 2 of an air pressure regulating valve 1, which regulates air pressure inside a cabin 101. A buoyant body 9 is attached to the disc-shaped closing lid 6 installed to the duct 2 so as to be rotatable around a rotation shaft 7. The buoyant body 9 receives a buoyant force from water when immersed in the water. Since the side of the closing lid 6 in which the buoyant body 9 is attached is thereby floated in the water, the closing lid 6 automatically rotates around the rotation shaft 7 so as to close a ventilation port 2a.

Abstract: 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.

Abstract: The present invention provides a water inflow prevention device that prevents an inflow of water into an aircraft when the aircraft lands in water through a communication passage allowing the inside and outside of the aircraft to communicate with each other. The water inflow prevention device includes a mesh part provided in the communication passage, through the mesh part a fluid flowing through the communication passage passes.

Abstract: The present invention provides an aircraft safety device which can reliably prevent explosion of a fuel tank even if an inflammable gas is ignited. A safety device for explosion-proofing a fuel tank which stores fuel of an aircraft includes: a flame propagation blocking part which blocks propagation of a flame from the outside to the inside of the fuel tank through a ventilation passage which allows ventilation between the inside and the outside of the fuel tank; and a gas supply suppressing part which, when heated by the heat of the flame, suppresses supply of an inflammable gas containing the fuel gas to the flame through the ventilation passage.

Abstract: The present invention provides a water inflow prevention device for aircraft, working when landing in water, the device including: a blocking body for blocking a flow channel from an outside of the aircraft when landing in water, the flow channel allowing the inside and outside of the aircraft to communicate with each other, and a valve element of a pressure adjusting valve being positioned in the flow channel; and a connection part that is deformed when landing in water, wherein the blocking body is supported by a member constituting an end of the flow channel on a side outside the aircraft through the connection part, and the connection part is deformed in a direction so as to block the flow channel by the blocking body, with use of force of water acting on the blocking body when landing in water.
