摘要
A turbine rotor blade is additively manufactured and includes an airfoil body including a concave pressure side outer wall and a convex suction side outer wall that connect along leading and trailing edges. A shank is at a radial inner end of the airfoil body, and at least one angel wing extends laterally from at least one side of the shank. A coolant transfer passage is defined through the at least one angel wing. The coolant transfer passage fluidly couples a first wheel space portion defined between the shank and a first adjacent shank of a first adjacent turbine rotor blade and a second wheel space portion defined between the shank and a second adjacent shank of a second adjacent turbine rotor blade. The coolant transfer passage allows coolant to pass between wheel space portions of adjacent turbine rotor blades.
