Abstract
The airfoil shaped body has a separate leading edge portion (14) spaced from the main body (12). Slots (22) thereby formed discharge cooling air parallel to surface (38) of the main body. A step change across the slot between the leading edge surface (52) and the main body surface (38) facilitates smooth introduction of cooling air.
