Abstract
A turbine airfoil includes a plurality of internal ribs joined to laterally opposite first and second sidewalls to define a serpentine cooling circuit therein. A span rib extends longitudinally between a root and tip of the airfoil. And, a slant rib extends obliquely to the span rib to define respective portions of the serpentine circuit longitudinally above and below the slant rib.

A turbine airfoil comprising:
- first and second sidewalls joined together at chordally spaced apart leading and trailing edges and extending longitudinally from a root to a tip;
- said sidewalls being spaced apart from each other between said leading and trailing edges and joined together by a plurality of internal ribs defining a serpentine cooling circuit;
- and
- said ribs include a span rib extending longitudinally between said root and tip, and a slant rib extending obliquely to said span rib to define respective portions of said serpentine circuit longitudinally above and below said slant rib.
