摘要：A turbine blade (100) includes a convex suction side wall (112), a concavepressure side wall (110), a tip wall (114), an internal cooling circuit (146), and a plurality of

tip edge channels (144). The tip wall (114) is recessed from a first tip edge (130) of thesuction side wall (112) and a second tip edge (132) of the concave pressure side wall (110)to define a suction side wall tip section (138) and a pressure side wall tip section (140),and the suction side wall tip section (138) is shorter than the pressure side wall tip section(140). The internal cooling circuit (146) is formed at least partially between the convexsuction side wall (112), the concave pressure side wall (110), and the tip wall (114). Theplurality of tip edge channels (144) formed through the first tip edge (130) of the convexsuction side wall (112) extend to the internal cooling circuit (146). Methods ofmanufacturing turbine blades (100) are also provided.
