ABSTRACT:
Extinction device with a generator of gas through combustion of a pyrotechnic block connected to means of distributing said generated gas in the fire zone. The device further comprises means of regulating the pressure generated in order to impose an oxygen concentration profile in the fire zone. Said regulation means may for example be a controlled valve or arise from the lay out of the pyrotechnic generator.The device is particularly suited to aircraft engine fires since it does not use halogenated fire extinguishing agents.
