<p>The aircraft (1) has a base body (2), at which three vertically acting primary drive units (3) are held, which clamp a plane. The plane is arranged at the same height or above the center of gravity (SP) of the aircraft in relation to the gravitational direction. Two horizontally acting secondary drive units (4) are provided, whose active force transmission points are arranged below the plane. The force transmission points of the secondary drive units clamp another plane, and the center of gravity is arranged in or adjacent to the latter plane.</p> |
