The invention provides, in vertical and oblique lift and descent, horizontal flight and hovering, for maintenance of attitude of an airframe, using a single wing, large blades and a single large rudder, under divergent airflow. To change attitude in hovering from horizontal to vertical, in case three wings are provided on the airframe, the output of an engine mounted on a wing at the front part of the airframe is increased, the lifting power is increased and the front part of the airframe rises from the horizontal. Then output of an engine of the rear part of the airframe is reduced, and the lifting power of the rear part of the airframe is diminished. When an angle of the airframe is increased, a second wing located in the central part of the airframe is moved to a 90 degrees vertical direction and an output occurs so that the altitude of the airframe does not drop.
