Abstract
An air cooled turbine rotor blade with a leading edge region cooling circuit having pressure and suction side feed channels separated by a rib, where the feed channels are connected to metering and diffusion cooling channels formed in the pressure and suction side walls and the middle rib that discharge into three rows of exit slots on the leading edge of the blade. The trailing edge region cooling circuit includes rows of serpentine flow circuits each having an impingement channel along a suction side and a return channel in a middle that opens into metering and diffusion channels on the pressure side that discharges into exit slots on the pressure side of the trailing edge region. The middle of the blade is cooled with a multiple pass aft flowing serpentine flow circuit with metering and diffusion film cooling slots.
