  • Variable camber vane for a gas turbine engine
    Patent number: 4053256
    Abstract: Apparatus for controlling the direction of flow of the working medium gases in the compression section of a gas turbine engine is disclosed. Vanes are disposed across the flow path for the medium gases to direct the flow to a preferred downstream angle. In one embodiment vanes are disposed across the compressor exit passage. The camber of the vanes at the compressor exit is variable in response to engine operating conditions to conform the flow to a fixed optimum angle of entry into the combustion section.
