ON BOARD INERT GAS GENERATION SYSTEM

摘要

An on board inert gas generation system for an aircraft receives air from a relatively low pressure source such as low pressure engine bleed air or ram air and passes it to a positive displacement compressor (40) to increase the pressure thereof to be suitable for supply to an air separation module (48). The positive displacement compressor (40) comprises a high pressure ratio single stage supercharger with internal cooling.
