METHOD OF FIGHTING A FIRE IN A FLYING AIRCRAFT Russian patent published in 2015 - IPC A62C3/00 

FIELD: fire safety.

SUBSTANCE: in the fire break-out areas in the cavities-ducts the windows are made with sealed lids, which are retained in the closed state in the absence of fire and which are opened in fire break-out in this area by the reversing electromagnetic drive. Near each window with a sealed lid there is a container with the fire extinguishing agent, equipped with a siphon tube and an air nozzle connected to the cavity-duct through the pulse valve designed for creating repeated short-time explosive exhaust of compressed air with portions of extinguishing agent dispersed in them. Near each window a temperature sensor is mounted, giving signals to the fire extinguishing control. On the temperature sensor signal using the reversing electromagnetic valve the lid of this window is opened. The pulses of compressed air are supplied to the container with the fire extinguishing agent to create repeated short-time explosive exhaust of compressed air with portions of extinguishing agent dispersed in them. The flame is knocked down from the burning objects. The dispersed portions of the fire extinguishing agent are poured on the objects.

EFFECT: increased efficiency and rapidness of fire extinguishing in the air during flight of the aircraft.
