Abstract
An airfoil includes an interior surface, an exterior surface opposed to the interior surface, a pressure side, a suction side opposed to the pressure side, a stagnation line between the pressure and suction sides, and a trailing edge between the pressure and suction sides and downstream from the stagnation line. A first column of overlapping stagnation trench segments is on the exterior surface, and the stagnation line passes through at least a portion of each of the overlapping stagnation trench segments. At least one cooling passage in each stagnation trench segment provides fluid communication from the interior surface to the exterior surface.
