Abstract: A ring-shaped airfoil aircraft capable of taking off and landing vertically, and hovering, comprising: a fuselage, a cockpit; a passenger cabin, a power bay, a tapered tail rudder, a ring-shaped airfoil; a flight controller. The ring-shaped airfoil aircraft has the flying abilities for vertical takeoff and landing and hovering at a fixed altitude of multiaxial rotary wing powered aircraft, but compared with multiaxial rotary wing powered aircraft, its flight attitude is hardly in by air side flow, the flight attitude is more reliable. In addition, it can implement the airspeed of fixed wing ducted aircraft, and the flight energy consumption is much less than the existing fixed wing ducted aircraft, and its takeoff and landing are free of runways. The ring-shaped airfoil aircraft can obtain the lift for aircraft, reduce the drag to aircraft and enhance its flight safety performance.
