More Information
Summary:A rotor blade (52) for a gas turbine engine includes a platform (62), an airfoil (60) extending radially outward from the platform, a shank (64) extending radially inward from the platform, a dovetail (66) extending from the shank, and a cooling circuit (130) extending through a portion of the shank for supplying cooling air for impingement cooling at least a portion of the rotor blade and for channeling purge air downstream from the rotor blade into a cavity defined within the gas turbine engine.
