Abstract
A fire suppression system for an aircraft includes an air separation module configured to receive exhaust air and ram air, conditioned compressor bleed air, and any combination thereof. The air separation module is also configured to provide nitrogen-enriched air and inert gas. The nitrogen-enriched air flows into a nitrogen-enriched air distribution network for fuel tank inerting. The inert gas flows into an inert gas distribution network for fire suppression in areas of the aircraft other than fuel tanks.
Claims26
A fire suppression system for an aircraft comprising:
- an air separation module configured to receive exhaust air and intake air and configured to provide nitrogen-enriched air and inert gas;
- a nitrogen-enriched air distribution network into which the nitrogen-enriched air flows for fuel tank inerting;
- and
- an inert gas distribution network into which the inert gas flows for fire suppression in areas of the aircraft other than fuel tanks.
A method of fire suppression for an aircraft, the method comprising:
- feeding exhaust air and intake air into an air separation module;
- generating nitrogen-enriched air and inert gas in the air separation module;
- feeding the nitrogen-enriched air from the air separation module into a nitrogen-enriched air distribution network for fuel tank inerting;
- and
- feeding the inert gas from the air separation module into an inert gas distribution network for fire suppression in areas of the aircraft other than fuel tanks.
