Patent ID: 8206108

Claim:
A turbine blade, comprising: a convex suction side wall including a first tip edge; a concave pressure side wall opposite the convex suction side wall and including a second tip edge; a tip wall extending between the convex suction side wall and the concave pressure side wall and coupling the convex suction side wall to the concave pressure side wall, the tip wall is recessed from the first tip edge of the convex suction side wall and the second tip edge of the concave pressure side wall to define a suction side wall tip section and a pressure side wall tip section, the suction side wall tip section being shorter and thicker than the pressure side wall tip section; an internal cooling circuit formed at least partially between the convex suction side wall, the concave pressure side wall, and the tip wall; and a plurality of tip edge channels formed through the first tip edge of the convex suction side wall that extend to the internal cooling circuit.
