  • Cooling circuits for trailing edge cavities in airfoils
    Patent number: 6183194
    Abstract: An airfoil having a trailing edge cavity formed by a leading wall and a trailing edge connected by a pair of side walls which converge at the trailing edge to define a cooling passage of substantially triangular cross section; a plurality of guide vanes arranged within the passage, spaced from the leading wall and trailing edge, and configured so that cooling gas flow introduced a generally radial direction is forced to flow in a direction toward the trailing edge.
    Type: Grant
    Filed: November 30, 1999
    Date of Patent: February 6, 2001
    Assignee: General Electric Co.
    Inventors: Francisco Jose Cunha, David Anthony DeAngelis
