Title:
AIRCRAFT ENVIRONMENTAL CONTROL AND FUEL TANK INERTING COUPLING SYSTEM BASED ON MEMBRANE SEPARATION METHOD
Document Type and Number:
WIPO Patent Application WO/2018/233274
Kind Code:
A1
Abstract:
Disclosed is an aircraft environmental control and fuel tank inerting coupling system based on a membrane separation method. The dehumidification of gas in an aircraft environmental control system and the separation of oxygen and nitrogen in a fuel tank inerting system are realized respectively, based on the selective permeability of a membrane to water vapour/air and oxygen/nitrogen. In the coupling system, part of drying gas passing through a membrane dehumidification heat exchanger (5) enters a membrane air separator (9), and the other part thereof is cooled through a large expansion turbine (8) and then directed into a cockpit for refrigeration; and nitrogen-rich gas generated by the membrane air separator (9) is directed into a fuel tank for inerting. Oxygen-rich gas is mixed with gas supplied by the environmental control system, thus increasing the oxygen content of gas supplied by the aircraft cockpit.
