  • Leading edge cooling using chevron trip strips
    Patent number: 8690538
    Abstract: A turbine engine component has an airfoil portion having a leading edge, a suction side, and a pressure side and a radial flow leading edge cavity through which a cooling fluid flows for cooling the leading edge. The turbine engine component further has a first set of trip strips and a second set of trip strips which meet at the leading edge nose portion of the leading edge cavity to form a plurality of chevron shaped trip strips and for generating a vortex in the leading edge cavity which impinges on the nose portion of the leading edge cavity and enhances convective heat transfer.
    Type: Grant
    Filed: June 22, 2006
    Date of Patent: April 8, 2014
    Assignee: United Technologies Corporation

  • Enhanced serpentine cooling with U-shaped divider rib
    Patent number: 7445432
    Abstract: A cooling passageway for use in an airfoil prtrion of a turbine engine component having a pressure side wall and a suction side wall is provided. The cooling passsageway comprises a serpentine flow passageway through which a cooling fluid flows. The passageway has an inlet through which cooling fluid is introduced into the passageway, an inlet channel for receiving the cooling fluid, an intermediate channel, and an outlet channel. A divider rib extends from a location in the inlet channel to a termination in the intermediate channel to improve the heat transfer coefficients associated with the passageway.

  • Leading edge cooling using wrapped staggered-chevron trip strips
    Publication number: 20070297916
    Abstract: A turbine engine component has an airfoil portion having a leading edge, a suction side, and a pressure side and a radial flow leading edge cavity through which a cooling fluid flows for cooling the leading edge. The turbine engine component further has a staggered arrangement of trip strips for generating a vortex in the leading edge cavity which impinges on a nose portion of the leading edge cavity.
