Method and apparatus for cooling gas turbine engine rotor blades

A method for fabricating a rotor blade includes casting the turbine rotor blade to include a shank (64), and a platform (62) having an upper surface and a lower surface (182), and coupling a first component (106) to the rotor blade such that a first substantially hollow plenum (180) is defined betwe...

Zusammenfassung:A method for fabricating a rotor blade includes casting the turbine rotor blade to include a shank (64), and a platform (62) having an upper surface and a lower surface (182), and coupling a first component (106) to the rotor blade such that a first substantially hollow plenum (180) is defined between the first component, the shank, and the platform lower surface.
