Known wheel [U.S. Pat. Of the Russian Federation No. 2211366, publ. 27.08.2003, bull. No. 24 / Litvinenko A. M. - application No. 2002104027 / 06 dated 14.02.2002]. The technical result consists in the simplification of the design, improving reliability, providing protection when drilling relatively cheaper and ensuring modularity and maintainability, is ensured by the fact that the wind turbine containing the hub, the blades, made in the form of sailing wings, spars, rope, D-shaped front edge, according to the invention sailing plumage made in the form of elastic plates, the front edge of which has the form of an arch and provided with holes for the spar.

The disadvantage of this wind turbine is the inability to use tissue membranes sailing type.

Closest to the claimed combination of essential characteristics is a wind wheel [EN 2383774 C1, F03D/02, 10.03.2010]. This wheel includes a hub, main rotor blades and secondary blades with rotary elements in the form of an arc.

Its disadvantage is the difficulty in ensuring the twist of the blades, which, as is known, provides russiaandeurasia characteristics, as well as relatively complex cutting sailing plumage.

The invention is aimed at simplifying and cheapening the construction by improving manufacturability.

This is achieved by the fact that wind turbine wind generator-containing hub, main rotor blades and secondary blades with rotary elements in the form of an arc, according to the invention arc rotary element provided with a hinge, in which the formation of additional blades fixed the angle of the l-shaped lever, with its first side attached to a cable tensioning device and the second party through the hinges attached system balancers, while sailing plumage additional blades are made in the form of loops of ribbon, the ends of which are secured to the beams, and the loop itself thrown over the rope.

The achievement of the technical result is the rational execution of additional blades.

The wind wheel is a wheel hub 1, is connected with the main monolithic blade 2, the end of which is bolted connections 3 screwed arc 4 rotary member with the teeth 5 and PA the AMI 6. 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.

- cheapness and ease of starting materials (tape);

- simplicity and reliability of the tensioning mechanism - Fig.4;

- high manufacturability, ease of Assembly;

the modularity provided by the possibility of the same type execute several blades;
