The spanned turbine structure serves for the conversion of wind power through rotation on a fixed plane around a horizontal axle (6). The structure comprises a rim (1), a spoke centre (3) and blade spokes (13). The rim and the spoke centre are fastened to each other by the blade spokes spanned between them and attached to them. The blade spokes are arranged in two rows, i.e. their points of attachment are on the two ends of the cylinder jacket of the spoke centre. The individual blade spokes can be flexibly turned around their axles coinciding with the straight line designated by their points of attachment on the rim and the spoke centre. This axle of the blade spokes is not identical with the median of the blades. The blade spokes, when in operation, adapt to the velocity and direction of the wind separately and quickly whereby the wind turbine works with satisfactory efficiency even when the plane of rotation of the turbine is not perpendicular to the wind direction. Accordingly the turbine need not be turned, furthermore its number of revolutions is self-limited. It can be set on slim, stayed posts and power take-off is simple. |
