Abstract
The present subject matter discloses a turbine component including a platform and an airfoil extending radially upward from the platform. A plurality of curved cooling passages may be defined in the platform. Each of the curved cooling passages may have at least one end disposed at an exterior surface of the platform. Additionally, each of the cooling passages may be configured to direct a cooling medium through the platform.
Claims20
A turbine component comprising:
- a platform;
- an airfoil extending radially upward from said platform, said airfoil including a pressure side and a suction side;
- a plurality of concentric curved cooling passages defined in said platform, each of said plurality of cooling passages extending between a first end and a second end, at least one of said first end or said second end being disposed at an exterior surface of said platform, each of said plurality of cooling passages defining a constant radius between said first and second ends;
- and
- wherein each of said plurality of cooling passages is configured to direct a cooling medium through said platform.

A turbine component comprising:
- a platform;
- an airfoil extending radially upward from said platform, said airfoil including a pressure side and a suction side;
- a plurality of non-concentric curved cooling passages defined in said platform, each of said plurality of cooling passages being configured to direct a cooling medium through said platform, each of said plurality of cooling passages extending from a common end;
- and
- wherein a common cooling medium inlet supplies the cooling medium to each of said plurality of cooling passages, the common cooling medium inlet being disposed adjacent to the common end.
