  • Nitrogen gas system with diverter valve
    Patent number: 9027885
    Abstract: A nitrogen gas system for an aircraft is provided and operable in warm-up and normal modes. The system includes an air separation module (ASM), a line to transport nitrogen enriched air (NEA) from the ASM to a fuel distribution system and a diverter valve disposed on the line and configured to divert the NEA away from the fuel distribution system during warm-up operations.
    Type: Grant
    Filed: September 27, 2012
    Date of Patent: May 12, 2015
    Assignee: Hamilton Sundstrand Corporation
    Inventors: Khem Vanwijak Eowsakul, James P. Hurst, Christina W. Millot

  • On-board inert gas generation system with air separation module temperature control
    Patent number: 7828874
    Abstract: An on-board inert gas generation system is disclosed that includes an air separation module that is configured to produce nitrogen enriched air from a non-enriched air. The non-enriched air to the air separation module has a desired operating temperature range. A compressor system is in fluid communication with the air separation module. The compressor system is configured to rotate at a speed and provide the non-enriched air to the air separation module. A controller is in communication with the compressor system and is configured to reduce the speed in response to a parameter reaching an undesired value, which would result in a non-enriched air temperature that would exceed the desired operating temperature range. The reduced speed is selected to maintain the non-enriched air temperature within the desired operating temperature range.
