Abstract: A supplemental wing for a rotary wing aircraft rotates about a pitch axis between a forward flight position and a hover position. The supplemental wing generates lift and generates both positive and negative pitching moments that balance and that may passively rotate the supplemental wing to an equilibrium position. The supplemental wing may use power assist to overcome friction to move to the equilibrium position. The lift generated by the supplemental wing reduces at high forward speeds to preserve main rotor control authority. The supplemental wing rotates to avoid aft translation when in the hover position. The supplemental wing may be retrofitted to existing helicopters and flown using existing helicopter controls without pilot re-training.

Abstract: The Invention is a self-rescue system for an aircraft. The aircraft may be a flight module, a mission module, or a combined flight module and mission module of a modular and morphable air vehicle, or may be any other aircraft. The self-rescue system is modular and interchangeable and provides selectable capability to protect the flight module, the mission module, and any crew or cargo of the mission module in the event that the flight module or mission module suffers mishap or system failure during flight.

Abstract: An unmanned air module includes one or more rotors, engines, a transmission and avionics. Any of several different ground modules may be attached to the air module. The air module may fly with and without the ground module attached. The ground module may be manned. The air module may have two rotors, which may be ducted fans. The air module may include a parachute, an airbag and landing gear.
