More Information
Summary:The present embodiments set forth a blade (112) including an airfoil (12, 130) including an outer tip (28) having a floor (128), a leading edge (51) and a trailing edge (50), a concave pressure sidewall (20) and a convex suction sidewall (22) extending axially between corresponding leading and trailing edges (51, 50) and radially between the floor (128) and the tip cap (36). The airfoil (12, 130) further includes a tip cap (36) extending from the floor (128) of the outer tip (28) and coextensive with the pressure sidewall (20) and suction sidewall (22) and around the leading edge and trailing edge (51, 50). The tip cap (36) includes a squealer tip configuration including a suction side tip cap portion (136) and a pressure side tip cap portion (137). The suction side tip cap portion (136) and pressure side tip cap portion (137) extend unequal distances above the floor (128) providing for cooling fluid flow out of the tip cap (36).
