The aircraft comprises a rotor with a vertical axis arranged in a housing for generating a lift exceeding the weight of the aircraft. The housing is essentially shaped as a circular wing. A first way of guiding air is provided for controlling the air stream generated by the rotor, by means of which the position of the aircraft can be controlled in hovering flight. From hovering flight, the aircraft can be moved into a cruise flight, where the lift of the aircraft is generated aerodynamically by the circular wing of the housing and its forward thrust by a...


An aircraft comprising a housing shaped as an essentially circular wing for generating an aerodynamic lift in a horizontal air flow, means for generating a horizontal thrust in a principal forward direction, at least one nonpivotal driven rotor with an essentially vertical axis of rotation for generating a rotor air stream, said rotor being arranged in said housing and designed for generating a lift exceeding the weight of said aircraft, first air guiding means arranged within said rotor air stream adjustable for controlling said rotor air stream, said f...
