Abstract

A blade for a gas turbine engine (22) includes an airfoil body (68). The airfoil body (68) includes a pressure side wall (76), a suction side wall (78), and a tip end wall (130). The tip end wall (130) forms a blade tip (70). The airfoil body (68) forms a plurality of suction side wall passages (91) and a main body cavity (88). The suction side wall (78) includes an exterior wall segment (92) and an interior wall segment (94). The suction side wall (78) forms the plurality of suction side wall passages (91) between the exterior wall segment (92) and the interior wall segment (94). The interior wall segment (94) and the exterior wall segment (92) extend to the tip end wall (130). The plurality of suction side wall passages (91) extend through the tip end wall (130) to the blade tip (70). The interior wall segment (94) and the pressure side wall (76) form the main body cavity (88).
