ABSTRACT:
A hollow airfoil is provided having a pressure side wall, a suction side wall, a cavity formed between the pressure and suction side walls, a plurality of cooling ports disposed within the pressure side wall, and a plurality of passages, each extending between the cavity and one of the cooling ports. Each passage has a first wall adjacent the suction side wall, a pair of passage side walls extending substantially toward the pressure side wall, and a second wall adjacent the pressure side wall. In a first embodiment, each passage further includes a pair of fillets extending between the passage side walls and the second wall. In a second embodiment, each passage includes a jog adjacent each cooling port.
