Abstract
A coolable rotor blade 16 having an airfoil section 18 is disclosed. Various construction details are developed which increase the cooling effectiveness under the airfoil section 18 under a variety of operative conditions. In one detailed embodiment, an array of rows of cooling air holes has two staggered rows in the spanwise direction which are spaced spanwisely in the row and chordwisely from row to row in a predetermined manner to ensure adequate cooling to the leading edge region should the aerodynamic leading edge shift.
