Abstract
The inventive method for extinguishing fire in an aircraft cargo compartment (3) consists in injecting a substantially pure nitrogen from high-pressure storage cylinders (12), in simultaneously actuating a device (5) for separating air and supplying nitrogen and in continuously introducing the nitrogen produced by said air separation device (5) into the compartment (3).
Claims8
1-7. (canceled)
A method of extinguishing fire in an aircraft compartment, involving the steps of:
- a) introducing a flow of substantially pure nitrogen from a nitrogen-storage device into the compartment;
- b) starting up an air-separation device that supplies the nitrogen;
- and
- c) introducing nitrogen produced by the air-separation device into the compartment,
- wherein the air fed into the air-separation device is compressed air at a pressure not exceeding 5 bar originating from a compression stage of a turbocompressor unit belonging to the aircraft.
2 more elements
The method of claim 4, wherein it involves the later step of refilling the cylinder with nitrogen from the air-separation device.
