Abstract:
PROBLEM TO BE SOLVED: To provide a water flow-in prevention device which can more sufficiently prevent flowing of water into an aircraft at emergency landing on water, and which actuates more stably.SOLUTION: A device 10 for preventing flowing of water into an aircraft via an air pressure control valve 1 when an aircraft 100 including the air pressure control valve 1 for regulating an air pressure inside the aircraft lands on water, includes a lid 11 for communicating with the inside and outside of the aircraft and for blocking a flow passage (duct 2) in which a valve body 3 of the air pressure control valve 1 is located from outside of the aircraft when landing on water. The lid 11 is supported at an end part 2B on the outside of the aircraft of the duct 2 via a connection part 12 which deforms at landing on water. The connection part 12 deforms in the direction for closing the lid 11 by a force of water flowing into the duct 2 from the periphery of the duct 2 at landing on water, acting on the lid 11.SELECTED DRAWING: Figure 1
