  • 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
