  • Patent number: 8511979
    Abstract: A two-stage high pressure turbine includes a second stage vane having an airfoil with a profile substantially in accordance with at least an intermediate portion of the Cartesian coordinate values of X, Y and Z set forth in Table 2. The X and Y values are distances, which when smoothly connected by an appropriate continuing curve, define airfoil profile sections at each distance Z. The profile sections at each distance Z are joined smoothly to one another to form a complete airfoil shape.
    Type: Grant

  • Patent number: 8092178
    Abstract: The turbine blade comprises an airfoil having opposite pressure and suction sidewalls extending from a platform to a free end tip and in a chordwise direction from a leading edge to a trailing edge. The blade has two winglets extending in a chordwise direction from adjacent the leading edge to adjacent the trailing edge. Each winglet extends from the pressure sidewall upwardly and outwardly from the sidewall to provide a channel between them. Each winglet has a free end extending laterally beyond a surface defined by the pressure sidewall offset.

  • Publication number: 20100135822
    Abstract: The turbine blade comprises an airfoil having opposite pressure and suction sidewalls extending from a platform to a free end tip and in a chordwise direction from a leading edge to a trailing edge. The blade has a chamfer extending between the pressure sidewall and the tip. The chamfer extends in a chordwise direction, the blade having a plurality of cooling passageways, each extending from an inlet in fluid communication with a pressurized cooling circuit inside the airfoil to an outlet on the chamfer.

  • Publication number: 20090324400
    Abstract: The strut is for use in a gas turbine engine has body, typically having an airfoil shape, having a leading edge and a trailing edge. The leading edge has at least one gas inlet in direct fluid communication with at least one outlet located in the trailing edge through which gas may be redirected from the leading edge to the trailing edge through the strut for injection back into a wake region downstream of the strut.
