Definitions
- the present invention relates to fire extinguishing systems on board aircraft.
- the object of the present invention is to propose a method of extinguishing fire in an aircraft compartment enabling rapid and efficient action with equipment of reduced weight and cost.
- the method comprises the steps of introducing into the aircraft compartment where a fire has taken a flow of substantially pure nitrogen from a nitrogen storage device, starting an air separation device supplying nitrogen, and introducing into the compartment the nitrogen produced by the air separation device.
- the process comprises the step of continuing introducing into the compartment a small flow of nitrogen produced by the air separation device;
- the nitrogen storage device comprises at least one high-pressure bottle; the process comprises the subsequent step of reloading the bottle with compressed nitrogen from the air separation device.
- the method according to the invention makes it possible, with the nitrogen storage device, advantageously high-pressure bottles, to establish very quickly in the compartment to protect an oxygen concentration sufficiently low to prevent fire from spreading.
- the simultaneous start-up of a small and low-consumption air separation device then makes it possible to maintain this low concentration of oxygen for an unlimited time, thus avoiding any risk of fire recovery during the subsequent flight. .
- the pressurized nitrogen bottles used and emptied during the initial injection phase into the compartment can be subsequently, and in masked time, recharged by the nitrogen supplied by the air separation device, thereby greatly simplifying the maintenance of the entire system.
- FIG. 1 shows a feed line 1 for a low pressure gas injection ramp 2, typically less than 1.2 bar, in a load storage compartment 3 of an aircraft, called " cargo compartment "(not shown).
- Line 1 is connected to the nitrogen production outlet 4 of an air separation device 5, typically a polymer membrane permeator separating nitrogen and oxygen from the air, such as those marketed by the society
- the separating device 5 is fed with compressed air at a pressure of about 2 bar taken from a compression stage of a turbo-fuel unit.
- compressor 7 of the aircraft for example a propulsion turbine engine or an auxiliary unit APU.
- the supply line 1 comprises, in series, a flow control solenoid valve 9, a heat exchanger / cooler 10 and at least one filtration stage 11.
- the fire extinguishing system further comprises a battery of pressurized nitrogen bottles 12, capable of storing nitrogen at a pressure between 150 and 300 bar, and each provided with a pressure reducer / regulator 13 for supplying nitrogen at a pressure not exceeding 2 bar in a line 14 connected to line 1 via a nonreturn valve 15.
- a line 16 including a compressor 17 extends parallel to the line 14 between the bottles 12 and a dispensing valve 18 in the upstream part of the line 1.
- this line 1 is also connected at least one fire suppression nitrogen injection line 19 in at least one electrical equipment bay 20 of the aircraft.
- a battery of electrochemical nitrogen generators 21 electrically controlled, connected to the line 14, may be provided to supplement or supplement the supply of nitrogen by the bottles 12.
- the solenoid valves of the dispensing heads 13 of the bottles 12 are immediately actuated to inject by the ramp 2 a large flow of pure nitrogen expanded in the compartment 3.
- the separation device 5 is implemented to provide, in a sustainable manner, additional nitrogen flow in the compartment 3 while maintaining a concentration low oxygen avoiding fire reoccurrences.
