Abstract

An airfoil fairing (62) includes an airfoil section (64) that is formed of a fiber-reinforced composite wall. The airfoil section (64) has first and second radial ends (64e, 64f), pressure and suction sides (64c, 64d), leading and trailing ends (64a/64b) that join the pressure and suction sides (64c, 64d), an internal cavity (70), and a rib (72) that extends radially in the internal cavity (70). The rib (72) has a radial rib end (72a) at the first radial end (64e) of the airfoil section (64) and extends across the internal cavity (70) from a first rib side (72c) at the pressure side (64c) to a second rib side (72d) at the suction side (64d). The rib (72) defines at the radial end first and second shoulders (74, 76). The first and second shoulders (74, 76) define a radial notch (78) there between.
