Description
technical field [0001] The invention belongs to the technical field of aviation systems and relates to a dehumidification device in a green inerting system of an aircraft fuel tank. Background technique [0002] Fire or explosion in aircraft fuel system is one of the main causes of aircraft crashes. The fire and explosion protection capability of the aircraft fuel system is directly related to the survivability and vulnerability of the aircraft, as well as the utilization rate, cost and personnel safety of the aircraft. If the fuel tank has explosion-proof capability, even if it is shot or other reasons cause a fire, it will not be destroyed, and the aircraft can continue to be used after being repaired. vulnerability. The adoption of aircraft fuel tank explosion-proof technology can also increase the life-saving time, so that the aircraft has enough time to return to the voyage in the event of a fuel tank failure. In addition, it can also protect the aircraft in emergenc...
