<p>An airfoil (10) includes an interior surface (16), an exterior surface (18) opposed to the interior surface (16), a pressure side (20), a suction side (22) opposed to the pressure side (20), a stagnation line (24) between the pressure (20) and suction sides (22), and a trailing edge (26) between the pressure and suction sides (20,22) and downstream from the stagnation line (24). A first column (42) of overlapping stagnation trench segments (40) is on the exterior surface (18), and the stagnation line (24) passes through at least a portion of each of the overlapping stagnation trench segments (40). At least one cooling passage (44) in each stagnation trench segment (40) provides fluid communication from the interior surface (16) to the exterior surface (18).</p> |
