Abstract

An airfoil (60) includes a ceramic airfoil (60) that defines a leading edge (66a), a trailing edge (66b), a pressure side (66c), a suction side (66d), a first radial end (76), and a second radial end (78). The ceramic airfoil section has an internal cavity (68) and a rib (70) that divides the internal cavity (68) into a first radial passage (72) and a second radial passage (74). The first radial passage (72) is open at both the first radial end (76) and the second radial end (78), and the second radial passage (74) is open at least at the second radial end (78). A cooling passage circuit (80) includes a first radial leg (80a) through the first radial passage (72), a second radial leg (80b) though the second radial passage (74), and a turn leg (80c) outside of the internal cavity (68) at the second radial end (78). The turn leg (80c) connects the first radial leg (80a) and the second radial leg (80b).
