  • Turbine blade having improved flutter capability and increased turbine stage output
    Patent number: 10443389
    Abstract: A turbine blade, airfoil, and rotor stage for a gas turbine engine is disclosed. The turbine blade, airfoil, and rotor stage each includes an uncoated airfoil profile in accordance with Cartesian coordinate values of X, Y, and Z disclosed herein. The resulting airfoil exhibits high flutter margins, thus enabling the gas turbine engine to be operated at an increased power output while avoiding operational limitations required in known gas turbine engines.
    Type: Grant
    Filed: November 9, 2017
    Date of Patent: October 15, 2019
    Inventors: Douglas James Dietrich, Jeff Tessier, Megan Burke, Stephen Wayne Fiebiger, Roy E. Struble, Christopher Charles Williams, Alexander Vasili Rozendaal, Lonnie Adolphus Houck, III

  • Adjusted rotating airfoil
    Patent number: 9890790
    Abstract: A compressor component having an airfoil with a profile in accordance with Table 1 is disclosed. The compressor component, such as a compressor blade, has an increased surface area over a portion of the airfoil chord length. The increased surface area allows for a greater amount of air to be taken in by the airfoil, thus increasing the air flow through the gas turbine engine.

  • Adjusted stationary airfoil
    Patent number: 9523284
    Abstract: A compressor component having an airfoil with a profile in accordance with Table 1 is disclosed. The compressor component, such as a compressor vane, has a decreased surface area over a portion of the airfoil chord length. The decreased surface area compressor vane operates in conjunction with a compressor blade having an increased surface area.
