  • INTERNALLY COOLED TURBINE BLADE
    Publication number: 20240117742
    Abstract: An internally cooled turbine blade for use in a gas turbine engine includes a serpentine channel extending within the turbine blade for flowing cooling air through the interior of the blade. The turbine blade includes turbulators positioned within the serpentine channel to cause or increase turbulence of the cooling air flowing through the serpentine channel, increasing the heat transfer between the turbine blade and the cooling air before exiting a plurality of air outlets within the turbine blade.
    Type: Application

  • Vane platform cooling
    Patent number: 7625172
    Abstract: A vane cluster has a platform, a shroud, and at least first and second airfoils extending between an outer face of the platform and an inner face of the shroud. Each airfoil has a pressure side and a suction side. The pressure side of the first airfoil faces the suction side of the second airfoil. The cluster includes a cooling passageway system. The system includes at least one inlet in the shroud. At least one first feed passageway extends from the shroud to the platform through the first airfoil. At least one second feed passageway extends from the shroud to the platform through the second airfoil. A first platform cooling plenum is to the pressure side of the first airfoil. A second platform cooling plenum is to the suction side of the first airfoil.
