PROBLEM TO BE SOLVED: To provide a high-speed flight aircraft having a simple structure, requiring no complicated mechanism and enabling vertical take-off and landing. SOLUTION: During vertical take-off/landing and low-speed flight, a lift force is obtained by rotors 3 rotated together with a circular aerofoil 2. During high-speed flight, since flight is enabled only by the lift force of the circular aerofoil 2, by storing the rotors 3 inside the circular aerofoil 2, high-speed flight is enabled without being affected by the rotors 3. With such a simple structure as only to change a storage rate of the rotors 3 protruded from the circular aerofoil 2, a complicated mechanism is not required. COPYRIGHT: (C)2009,JPO&INPIT
