TURBINE ROTOR BLADE

A turbine rotor blade (120) is additively manufactured and includes an airfoil body (122) with a radially extending chamber (134) for receiving a coolant flow (136), a tip end (140) at a radial outer end (142) of the airfoil body (122), and a shank (148, 148A) at a radial inner end (152) of the airf...

More Information
Summary:A turbine rotor blade (120) is additively manufactured and includes an airfoil body (122) with a radially extending chamber (134) for receiving a coolant flow (136), a tip end (140) at a radial outer end (142) of the airfoil body (122), and a shank (148, 148A) at a radial inner end (152) of the airfoil body (122). The radially extending chamber (134) extends at least partially into the shank (148, 148A) to define a shank inner surface (154). An integral impingement cooling structure (160) is within the radially extending chamber (134). The integral impingement cooling structure (160) allows an exterior surface (170) of a hollow body (162) thereof to be uniformly spaced from the airfoil inner surface (132) despite the curvature of the chamber (134). The turbine rotor blade (120) has impingement cooling (160) throughout the blade (120).
