<p>The aircraft can achieve vertical flight using rigid supporting surfaces, with one or more closed or divided ring-shaped profiled surfaces in a round, circular or oval or multiangular form. An air stream is drawn through a centrifugal system and directed in the direction of the supporting surfaces. The angle of incidence of the surfaces can be varied as can their profile form. The intake opening of the air stream can be varied from the vertical to the horizontal and in all directions. The speed of the air stream can be increased with the aid of additional forces. Variable guide surfaces are used to direct the flow above or below the support surfaces.</p> |
