Flexible ram wing sail as a device for driving land or water vehicles

摘要

Wing sail, for driving water or land vehicles with a wing-like closed profile training with air inlet openings, which supplies the inner chambers between the profiles (3a to 3i), depending on the direction of incidence of the air flow, with sufficient air pressure, and so the necessary shape of the wing sail upright receives, characterized in that air inlet opening rows (4a to 4i and 5a to 5i) along the luff (7) respectively right and left of the axis 2 (3) and within the wing sail movable flaps (6a to 6i) are located, which the air supply so that one of the two air inlet port rows (4a to 4i or 5a to 5i) is open, but the other is closed to ensure the dynamic pressure and thus the shape of the wing sail during operation.
