Abstract

A bowed airfoil is provided which includes a plurality of passages disposed between a pressure side wall and a suction side wall. The pressure and suction side walls extend widthwise between a leading edge and a trailing edge, and spanwise between inner and outer platforms. Passages extend spanwise between the inner and outer platforms. Ribs, each having a rib end, separate adjacent passages. Passage turns, each having an end wall, connect the passages. The end wall of each passage turn acutely converges with one of the side walls, and a first fillet extends between the acutely converging side wall and end wall. According to one embodiment, each rib end acutely converges with the other of the side walls, and a second fillet extends between the acutely converging side wall and rib end.
