Abstract: An aircraft that closely integrates thrust and aerodynamics to achieve VTOL flight, forward flight, and smooth transitions from VTOL to forward flight. The invention combines a Box wing, Ducted Rotors and movable Flaperons for VTOL and sustained forward flight of an aircraft. In forward flight, the concept uses a plurality of fixed Ducted Rotors to not only provide thrust, but also enhance dynamic lift and controllability by interacting closely with the two fixed primary lifting bodies of each ducted wing section. In VTOL flight and transitioning to forward flight, the Ducted Rotors direct air through movable Flaperons attached to the trailing end of the ducted wings, providing smooth power, controllability, and aircraft orientation throughout transition. Throughout all phases of flight, differential actuation of Ducted Rotors and Flaperons provide control.
