Abstract
An airfoil assembly for a gas turbine engine according to an example of the present disclosure includes, among other things, an airfoil including an airfoil section extending from a root section. The airfoil section extends between a leading edge and a trailing edge in a chordwise direction and extending between a tip portion and the root section in a radial direction. The airfoil section defines a pressure side and a suction side separated in a circumferential direction. A root mount includes first and second mount members secured to circumferentially opposed sides of the root section. Arcuate circumferential faces of the first and second mount members are dimensioned to pivotably mount the root section to a hub in an installed position. A method of assembly is also disclosed.
