摘要：
A turbine rotor blade with near wall cooling that provides full coverage film cooling for the leading and trailing edges. A first layer of chordwise extending cooling channels are formed on a spar, and a second layer of chordwise extending cooling channels are formed over the first layer to provide near wall cooling. Open ends of the two layers of channels on both pressure and suction side walls of the blade open into a leading edge slot and the trailing edge wall sides to discharge film cooling air.
