ABSTRACT:
A rotor blade design capable of long term reliable operation in a high temperature environment is disclosed. Various cooling concepts adapted to preserve the mechanical properties of the blade material are developed. A cooling system for the blade is built around a multiple supply construction in which cooling medium from a first supply is mixed internally of the blade with cooling medium from a second supply.
