Stator vane having a fanned cooling hole array on a large fillet between airfoil and platform

摘要

A turbine airfoil (41) has a fillet (44) connecting a nominal portion of the airfoil (41) into an end wall (43). Cooling holes (66,68,70) are formed over a greater circumferential extent in the fillet (44) than cooling holes (60) through the nominal portion of the airfoil (41).
