REDUCING VARIATION IN COOLING HOLE METER LENGTH

摘要

An airfoil body (100; 200) includes an airfoil wall (102; 202) defined between an internal cavity surface (104; 204) and an external airfoil surface (106; 206). A pad (108; 208) extends from the internal cavity surface. A cooling hole (110; 210) extends from the external airfoil surface, through the airfoil wall and through the pad for fluid communication through the airfoil wall.
