Abstract
A propulsion system for a rotorcraft includes a mast having an axis of rotation. A hub assembly is coupled to and rotatable with the mast. The hub assembly has a gimballing degree of freedom relative to the mast. A gimbal lock system is positioned about and rotatable with the mast. The gimbal lock system includes a hub lock and an actuation assembly that is operably coupled to the hub lock. The hub lock is translatable relative to the mast between a disengaged position with the hub assembly to enable the gimballing degree of freedom and an engaged position with the hub assembly to disable the gimballing degree of freedom. The hub lock is rotatable about the axis of rotation relative to the mast and the actuation assembly.
