Abstract
An electric propulsion system includes a static mast fixed to the airframe and a secondary mast positioned in overlapping arrangement with the static mast. The secondary mast defines an axis of rotation. An elastomeric bearing is arranged at an interface between the static mast and the secondary mast. An actuator assembly includes at least one actuator connected to the secondary mast. The actuator assembly is operable to pivot the secondary mast relative to the axis of rotation.
