The engine consists of two (or more) circular discs arranged one on top of another (spaced apart), that are fitted with movable air flaps on their bottom sides. These discs with their air flaps, that are distributed evenly over 360 degrees, form a rotor whose plane of motion is horizontal. As soon as wind pressure acts on the rotor (regardless of direction), those air flaps whose opening is opposite the wind pressure open all the way to the stop on the lower disc. This allows the wind pressure to act on the rotor optimally. On the non-working side, the air flaps are pressed up (closed) by the wind pressure, thus offering only slight resistance to the wind. The air flaps which are widest open (are in the area of optimum wind pressure) at the moment cause advance opening of those flaps which will come into the area of optimum wind pressure next, by a suitable mechanism (e.g. by a Bowden cable). By stacking several rotor discs one on top of another and by appropriate design, considerable energy can be obtained even at relatively small wind pressure. The lowest common denominator of this principle is a rotor having air flaps attached in vees to its booms (V), which open on the working side and close on the non-working side (automatically by wind pressure). An optimum is achieved by the design described, however, and ... Original abstract incomplete. <IMAGE>
