The technical field to which the invention relates.

The invention relates to power engineering and can be used to convert the energy of the moving medium (water, air, steam) into electricity.

The level of technology

Known power plant with an active method of processing wind, characterized by the use of a wind turbine with horizontal shaft, radial blades in the rotor, the deflector body from rotating and stationary parts, drives rotation of the rotors, the drive motor rotor and generator, and the drive motor rotor further comprises or is made with a built-in planetary gear

(see patent RU 2327898, IPC F03D 1/02, publ. 27.06.2008,).

The disadvantage is that the rotors are driven by the electric motors, and therefore the power plant cannot be run without summing up the electricity from the external power supply, and then to ensure that this power plant will be selected portion of her power and also quite difficult drives rotation of the rotor, which increases the production of electrical installations.

Closest to the technical essence and the achieved positive effect and adopted by the author for the prototype is a wind turbine with rotor Magnus,characterized by a wind turbine with horizontal shaft, radial blades in the form of cylinders, drives rotation of the cylinders, which are made in the form of type Savonius rotors, mounted on axes of rotation of the cylinders and rigidly connected with them (see patent RU 2189494, IPC7F03D 1/00, publ. 20.09.2002,).

The downside is that the built-in cylinders and role drives the rotor Savonius, which blades, consisting of semi-cylinders, although it will cause the cylinder to rotate, but as the Magnus effect most closely affects the shape of the rotation with closed surfaces (cylinder, sphere), and the Savonius rotor is not, this will reduce the surface area of the cylinder affected by the Magnus effect with the greatest results.

Disclosure of inventions

In the invention the task is to bring the rotor into rotation around their own axis to use the Magnus effect due to the energy incident on these rotors stream in order to eliminate the use of electric motors for rotation of the rotors.

The technical result that can be obtained using the present invention is to simplify the whole structure of the unit, increasing its capacity, reducing the cost of manufacture, increased reliability and more cheap electricity.

The technical result is achieved when amodu rotary-vane impeller power generation unit based on the Magnus effect, containing the shaft, rotors and blades, it is further provided with a ring rotor, fixed to the body, kinematically connected with the rotor and providing the rotors rotate around their own axis, and blades mounted on a common shaft and are driven shaft.

Thus under the influence of the flow of the blade located on the same shaft with the rotors start to rotate the shaft and result in rotational movement around the axis of the common shaft with blades of the rotors.

The ring rotor kinematically connected to the rotor and at the time of rotation of the rotor around a common shaft with blades provides the rotors rotate around their own axis by means of bearings of the rotors on the edge of the ring.

The clutch rotor and ring rotation of the rotors providing rolling rotors on the edge of the ring may be a gear, friction or other known method, depending on the design capacity of the device and the environment of its application.

The parameters and shape of the elements of the device is determined depending on the design capacity of the device and the environment of its application.

Materials, which are used for the elements of the device are the same as those for similar devices.
