Abstract: A variable pitch airfoil assembly for an engine includes a disk having an annular shape extending about an axial direction and an airfoil coupled to the disk via a platform. The airfoil extends outwardly from the disk in a radial direction and is rotatable relative to the disk about a pitch axis. The variable pitch airfoil assembly further includes a damping element positioned at least partially within the disk exterior of and adjacent to a perimeter of the platform so as to provide vibration damping by friction between the damping element, the platform, and the disk while also allowing for a pitch change of the airfoil.
