  • Turbomachine component having an airfoil core shape
    Patent number: 8814511
    Abstract: A turbomachine component includes a turbine stator nozzle member having an airfoil core shape. The airfoil core shape includes a nominal profile substantially in accordance with Cartesian coordinate values of X, Y, and Z set forth in TABLE 1, and wherein X and Y are distances in inches which, when connected by smooth continuing arcs, define airfoil profile sections at each distance Z in inches, the profile sections at the Z distances being joined smoothly with one another to form a complete airfoil core shape.
    Type: Grant
    Filed: August 9, 2011
    Date of Patent: August 26, 2014
    Assignee: General Electric Company
    Inventors: Benjamin Michael Check, Craig Allen Bielek, Hal Feaster Pollard, Sivaraman Vedhagiri
