Abstract: A five-wing aircraft transitions smoothly between vertical and horizontal flight modes, and enhances pitch neutrality of the aircraft when in flight at all speeds to improve flight efficiency. The aircraft includes a fuselage, a fixed wing assembly coupled to the fuselage and having a front fixed wing and a rear fixed wing, the front fixed wing coupled to the front portion of the fuselage and the rear fixed wing coupled to the rear portion of the fuselage, the front fixed wing and rear fixed wing being connected together by winglets, a tilt-wing pivotably mounted to the central portion of the fuselage, and a pair of rotary wings coupled to the tilt-wing. The tilt-wing pivotably adjusts to permit the aircraft to transition smoothly between vertical and horizontal flight. The rotary wings generate thrust or lift depending on the orientation of the tilt-wing.
