Abstract
A turbine engine component for use in a small engine application has an airfoil portion having a root portion, a tip portion, a suction side wall, and a pressure side wall. The suction side wall and the pressure side wall have the same thickness. Still further, the turbine engine component has a platform with an internal cooling circuit.
Claims22
A method for design a turbine engine component comprising the steps of:
- designing an airfoil portion having a root portion, a tip portion, a first wall forming a suction side wall, a second wall forming a pressure side wall, and a supply cavity;
- and
- said designing step comprising increasing wall thickness of said first and second walls from a point near said root portion to a point near said tip portion.
A turbine engine component for use in small engine applications comprising:
- an airfoil portion having a root portion, a tip portion, a suction side wall, and a pressure side wall;
- and
- said suction side wall and said pressure side wall having the same thickness.
A platform of a turbine engine component comprising:
- exterior walls and an as-cast cooling circuit positioned internally of said exterior walls.
