Rotary element through an air gap interacts with the stator element 7, which is shown conventionally and fixed on a rotating basis, associated with the bearing housing hub. Arc 4 rotary element provided with a hinge 8, which establishes the angle of the l-shaped lever, with its first side 9 is attached a tension device 10 with the cable 11. The second side 12 of the l-shaped arm via the hinge 13 is attached to the rocker 14, the hinges 15 which reinforced beams 16. Sailing plumage made in the form of loops of tape 17, the ends 18 and 19 which are fixed to the beams 16, and the loop is thrown over the rope 11.

Wind wheel operates as follows. At clash of the wind flow perpendicular to the plane (Fig.1) from the aerodynamic point of the blade 2 wheel moving. This point is increased by the additional action of the blade, which is formed by a cable 11, taut spring 10 (rising edge), and balancers (down edge). The very plane of the blade formed by the belts 17, scheme Spasovka which is shown in Fig.2. It is also possible in the tension of the flexible element with the clamping device 10, and also has the possibility of providing twist by the location of the tensioner and balancer in different planes. If BP is not the same wind turbine rotor elements, interacting with the stator elements, suggest recent voltage, then transmitted to the consumer.
