<p>The air accumulation is formed under the wings by flow speed reduction or direction towards the ground by a rotating system under the wings. The rotating system comprises several disc rotors powered by electric motors and act at right angles into the wings. During flight, the system is retracted into the wings and the slis on the lower side are sealed off by slides. By varying the speed of the individual motors and adjusting the angle of border strips, the air cushion volume can be controlled to facilitate stabilisation of the aircraft during take-off and landing.</p> |
