摘要: A coolable rotor blade having an airfoil having two serpentine passages is disclosed. Various construction details are developed for providing cooling to the leading edge region and the trailing edge region of the airfoil. In one detailed embodiment, the airfoil trip strips in the passages having constant height and constant pitch over each leg in most legs of the passages except for the legs closest to the edge regions of the airfoil.
