| 摘要 | PURPOSE:To efficiently adjust a wing correspondingly to a change of wind direction and wind velocity, by constituting the captioned said wing from a wing spar shaft, connecting leading edge parts of ribs provided to both ends of the wing, tension wires, extensibly provided between rear end parts of the ribs, and flexible films, extensibly spread between the wing spar shaft and the tension wires. CONSTITUTION:Wing end ribs 1, consisting of a plate member in length almost equal to the wing spar, are arranged to both end positions of a wing, and a wing spar shaft 2, extended through leading edge parts of the ribs, is rotatably provided, while tension wires 3 of a steel wire and the like are extensibly provided between rear end parts 1a of the ribs, and flexible films 4 of cloth, film, etc. are spread between the wing spar shaft 2 and the tension wires 3, further airfoil spars 6 are formed around the wing spar shaft 2 by using a flexible material of rubber or the like. This sail wing can be utilized for wind mills, curved, deformed and automatically changed to adequately sectional shape by the airfoil spar 6 and the flexible film 4 in accordance with the direction or velocity of a wind. | ||||||
