  • Patent number: 5511374
    Abstract: A method and apparatus for supplying cooling air on vehicles such as high speed aircraft includes diverting high pressure air from the compressor section of a gas turbine engine, cooling this air in a heat exchanger, compressing the air and subsequently cooling the air in a second heat exchanger to provide cooled, high pressure air. One embodiment additionally provides cooled air at relatively medium pressure and relatively low pressure, while the alternate embodiment additionally provides cooled air at relatively low pressure.
    Type: Grant
    Filed: January 31, 1995
    Date of Patent: April 30, 1996
    Assignee: United Technologies Corporation
