  • Apparatus and methods for cooling turbine bucket platforms
    Patent number: 7147439
    Abstract: A bucket has an airfoil, a root and a platform between the root and airfoil. The airfoil includes a serpentine cooling circuit, and the platform includes plural cavities, one or more cavities each having a serpentine cooling circuit. Cooling medium is drawn from one of the passages of the airfoil cooling circuit for flow in the platform cooling circuit and for return either to another passage of the airfoil circuit or to a trailing edge exit. The platform cooling circuits thus convectively cool both high and low pressure sides of the platform.
