Abstract
A gas turbine engine airfoil leading edge includes depressions therein longitudinally spaced apart and centered on stagnation points. The depressions stay filled with relatively stationary air during engine operation and reduce the heat load at the leading edge, which is primarily cooled by an internal supply of cooling fluid.
