Abstract

A coolable gas turbine engine airfoil for a gas turbine engine suitable for a blade or vane includes an outer airfoil wall with pressure and suction sides extending chordwise between leading and trailing edges of the airfoil, a leading edge cooling plenum formed between a forward most span rib and the outer wall along the leading edge of the airfoil, and a cooling air channel within the airfoil bounded in part by the forward most rib. A slotted cooling air impingement element is disposed in the span rib for impinging cooling air from the channel on an interior surface of the outer airfoil wall along the leading edge of the airfoil. One embodiment of the slotted cooling air impingement element is a single longitudinally extending slot extending along almost an entire length of the forward most rib and the longitudinally slot preferably includes longitudinally spaced apart rounded ends. In another embodiment of the airfoil, the slotted cooling air impingement element is includes two or more closely spaced apart longitudinally extending slots extending along almost an entire length of the forward most rib and each of the longitudinally extending slots preferably has longitudinally spaced apart rounded ends
