Abstract: A wind power plant has a turbine with its axis of rotation (1) substantially at right angle to wind direction, and wings (2) protruding from the axis (1) and the wings (2) have their crossways extension essentially in vertical direction. The wings (2) can be in odd as well as even number distributed around the axis of rotation (1), and composed of wing elements (21-24 and 31, 32) of optional length. For formation of the wings (2), the wing elements (21-24) are connected into a torsion link configuration (like a row of pairs of scissors), and thus synchronously movable in relation to each other. To adjust the extension of the wing elements (21-24 and 31, 32) an along the axis of rotation (1) adjustable sleeve means (4) is present, to which the inner end of an inner wing element (21) is connected.
