An apparatus for providing lift to an aircraft comprising at least one rotating lifting device (RLD) formed of a pair of RLD segments extending from a common vertical support pivotally supported by the aircraft, a drive operable to rotate the at least one RLD relative to the aircraft and a lock operable to fix the at least one RLD relative to the aircraft at a plurality of orientations. The RLD segments may include a plurality of aerodynamic adjustment features to adjust the aerodynamic profile of the RLD segments as the RLD is converted from a rotating lifting body to a stationary lifting body.
