Abstract

A gas turbine engine airfoil (60) includes an airfoil section (61) that has an airfoil wall (62) and a rib (70) that are formed of a ceramic matrix composite ("CMC"). The airfoil wall (62) circumscribes an internal cavity (66) for receiving cooling air. The airfoil wall (62) defines leading and trailing ends (62a, 62b) and first and second sides (62c, 62d) that join the leading and trailing ends. The rib (70) connects the first and second sides (62c, 62d). A metallic shield (72) is disposed in the internal cavity (66) and at least partially encloses the rib (70) to shield the rib (70) from the cooling air.
