  • Airfoil having reduced wake
    Patent number: 8419372
    Abstract: An airfoil of varying span-wise thickness comprising a suction side and a pressure side coupled together at a leading edge and a trailing edge, with the trailing edge comprising a plurality of spaced-apart wave-shaped projections. Exemplary embodiments provide airfoil geometry and/or trailing edge features to influence downstream wake flow. Methods of fabricating an airfoil for improved wake flow are also provided.
    Type: Grant
    Filed: August 22, 2011
    Date of Patent: April 16, 2013
    Assignee: General Electric Company
    Inventors: Trevor Howard Wood, Anurag Gupta, Ludwig Christian Haber, Philip Roger Gliebe
  • Rotary airfoils and method for fabricating same
    Patent number: 8083487
    Abstract: A method of fabricating an airfoil is provided. The method includes fabricating at least one airfoil including a suction side and a pressure side coupled together at a leading edge and a trailing edge, wherein the airfoil includes a plurality of first and second chord sections each extending between the trailing and leading edges, wherein at least one of the first chord sections extends outward from the pressure side of the airfoil at the trailing edge, and at least one of the second chord sections extends outward from the suction side of the airfoil at the trailing edge.
    Type: Grant
