The invention discloses an aircraft, which pertains to an aircraft. The existing aircrafts in the world can be divided into two types by the method of resisting gravity, wherein, one type utilizes counterforce, such as rockets and helicopters, and the other type adopts air power mechanism to create a lifting force during moving, such as airplanes. The methods are in use and have defects. For instance, the airplanes and helicopters can not lose the helping role of the aerosphere. The proportion of fuel carried by the rockets is too large. The aircraft has the obvious advantages that the aircraft requires very small power to be driven and flying speed can be easily controlled.
