DESCRIPTION OF THE INVENTION
The invention relates to vetrotehnike and can be used to provide various energy consumers, especially in mountainous areas.
Known wind turbine comprising a rotary base on their hubs airflow feathered frame unit and including rollers on them with the inserted driving and driven sprockets covered by an endless chain on which the rotary blades has a variable airfoil. Furthermore, the wind turbine comprises a mechanism set the optimum angle of attack of the blades comprising the bearing and guide rollers mounted on each blade, interacting with the rails connected by means of pivot links to the chassis to form a parallelogram mechanism with articulated links connected with hubs and one of shaft - with an electric generator by means of a flexible coupling (see AS SU №1686217, MKI 5 F 03 D 5/02.).
A disadvantage of the known device is the complexity of construction due to the complexity of construction machinery installation optimum angle of attack of blades.
In addition, the wind turbine has low efficiency, since the movement of the traction organ used only lifting force of wind acting on the operating element (blade).
The closest to the claimed technical solution is a wind turbine comprising a traction body - chain transmission, comprising leading and three driven sprocket arranged on a frame connected to the rotary base equipped with an actuator, an endless chain encompassing the sprocket. In the endless chain of pivotally mounted blades. Thus the wind turbine blade includes a mechanism for changing the angle of attack comprising hinge links, one of which is arranged adjustable in length, with slides installed in them. Furthermore, a wind turbine is provided with an automatic control unit, a speed sensor and the direction of air flow, the generator output power control sensor, and automatic control unit is connected to all sensors and executive base hinge link mechanism with adjustable length (cm. AS SU №1469206 , MCI 4 F 03 D 5/02).
The disadvantage of this wind turbine is a low efficiency due to use to move the chains with blades only lift the wind.
Moreover, wind turbine having a reference point in a plane, has a low resistance at high wind loads, which significantly reduces its efficiency.
The technical result of the claimed technical solution is to improve efficiency through the use of traction to move the body of the full aerodynamic force exerted on the blade, and performance by improving the reliability of the wind turbine that provides range extension perceptible wind loads.
The technical result is achieved by the wind turbine comprising a flexible drive, comprising master and slave elements placed on the frame, mounted on a swivel base, equipped with an actuator and a female master and slave elements, traction body with pivotally mounted on the blades therein, the automatic control unit an output power sensor monitoring a generator speed sensor, and the air flow direction, the mechanism of changing the blade angle of attack comprising hinge links with installed sliders, with one articulated link adapted adjustable in length, an electric generator connected to the drive element belt transmission further comprises a second flexible drive and mounting mechanism working branches traction bodies towards vector full aerodynamic forces acting on the blade, wherein the frame is formed as two, for each flexible drive, flat hinged trusses interconnected axes-couplers, wherein each blade is pivotally mounted traction on both bodies and mechanism changes the angle of attack of the blade is further provided with lockable sliders.
Furthermore, Fitting working branches traction bodies towards vector full aerodynamic forces includes a motor gear, two pairs of bevel gears, camshaft mechanism having two mutually perpendicular bevel gear pairs and setscrews with nuts arranged on the axes of the conical pairs placed on each hinge farm.
Moreover, installation of working bodies traction mechanism branches towards full aerodynamic force vector comprises more than one timing at each hinge farm.
Comparison of the technical solution to the prototype revealed distinctive features of it, therefore, it meets the criterion of "novelty".
Installing the operating branches traction authorities towards a full wind vector (resultant) force of the wind acting on the blades, allows to increase the efficiency of a wind turbine to 0.5-0.6 by the use of the resultant force of the wind effects on the blade.
Introducing a second parallel set flexible drive and combining it with the first through the axes-ties in a single spatial Four-structure with fixing each blade to the two traction organs improves the reliability of the design, which allows to select energy in the range of high speeds up to 40 m / s wind, leading to improving the efficiency of the inventive wind turbine.

Wind turbine for wind turbines WORKS AS FOLLOWS
In the event of a wind sensor 12, the speed and direction of flow Swivel downwind and sends a signal to the control unit 10 automatically. As a result, the actuator 8 base 7 is commanded, the base 7 is set in circular tracks, and the wind turbine becomes "the wind", with a concentrated stream of the wind affects the blade 6, forcing them to move together with the drive elements 5. The traction element 5 through the drive 1 element is driven to rotate the generator 9, which recorded output sensor 11, which, via block 10 acts on the automatic control mechanism for changing the angle of attack through the articulation link 13 with adjustable length and sliders 14, setting the optimum angle of attack of the blades, respectively, wind force.
