Abstract
A turbine engine component, such as a turbine blade, has an airfoil portion with a pressure side and a suction side. The turbine engine component also has a first cooling circuit within the pressure side for cooling the pressure side of the airfoil portion and a second cooling circuit within the suction side for cooling the suction side of the airfoil portion and for cooperating with a wrap around leading edge cooling circuit for creating a cooling film over the pressure side.
Claims16
A turbine engine component comprising:
- an airfoil portion having a pressure side and a suction side;
- a first cooling circuit within said pressure side for cooling said pressure side of said airfoil portion;
- a second cooling circuit within said suction side for cooling said suction side of said airfoil portion and for cooperating with means for creating a cooling film over said pressure side;
- a trailing edge internal circuit;
- and
- said first cooling circuit having an exit which delivers cooling fluid to said trailing edge internal circuit.
