The invention relates to the design of devices for generating electrical energy using the wind flow energy. The unit of energy supply consisting of a terrestrial platform, rotating propeller blades, the combined outer annular rim, interacting with one or more generators of electric energy on the annular rim of the propeller between alternating blades in the direction of rotation of the propeller mounted profiled twisted plane, which console with a minimum angle attack 
min docked to the console of the previous blade propeller, and the console with a maximum angle of attack max docked to the console followed by propeller blades. The invention improves the efficiency of the energy supply device in the ground conditions, lower unit costs and unit of electricity generated, but also helps to improve the environmental situation.
DESCRIPTION OF THE INVENTION
The invention relates to electrical engineering, namely to the design of devices for generating electric energy, which use energy of the wind flow.
Known energy wind turbine comprising a wind wheel and the diffuser blades which are fixed to the central hub axis of rotation, the torque transmission system and a generator (see the book "Wind" Ed D. de Renzo:... Translated from English ed ya... I.Sheftera -. M .: Energoatomisdat, 1982, p.134).
The disadvantage of this design is the presence of significant bending moments in the blades of the propeller, which limits the rotor diameter, and hence the power of the unit. The unit cost of such installations blades high. Thus the selection of the torque from a central propeller hub shaft reduces the efficiency of wind turbines as a whole.
and in such installations, periodic disruptions in the flow stream of the blades, which leads to the appearance of oscillatory processes resonant nature of low-frequency ranges. The impact of these processes on the environment has a negative impact both on the mechanisms and structures, as well as living organisms (see the book I.G.Horbenko "Sound, ultrasound, infrasound" Univ 2nd, revised and enlarged -..... M. : Knowledge, 1986 - s.178-180).
Known devices and Beskonsolnaya fastening structure with blades which the propeller blades mounted in the diffuser, and are mounted on the rotation axis and peripherally in the diffuser blades cavity. This peripheral part of the blades are connected to the rim interacting with one or more power generators (see. Patent the Russian Federation №2136957, MKI 7 F 03 D 1/00, 7/00 on the application №97121672 / 06 dated 09/12/97 was, publ . 10.09.99, at Bulletin №25, authors Kalashnikov SP, Malishkin VM -. Wind power device Beskonsolnaya mount the blades and method for controlling the propeller speed).
This design installation and the use of multiple generators contributes to the efficiency of its use. At the same time, although in this setting, and reduced level of dynamic oscillatory processes by increasing the rigidity of the periphery of the annular rim blades, shear processes in the flow blades have a place to wind flow, turbulence and the formation of the wind wheel is generated in the space of low-frequency oscillations.
The technical result of the proposed invention is to increase the efficiency of the energy supply device in the ground conditions, the reduction of the specific cost of the device and the electricity generated, but also the improvement of the ecological situation.
The invention consists in the fact that in the device the energy supply, consisting of a ground platform, pivoting propeller blades, the combined outer annular rim interacting with one or more generators of electric energy, on the annular rim of the propeller between alternating blades in the direction of rotation of the propeller mounted profiled twisted plane which console with minimal angle of attack min docked to the console of the previous blade propeller, and the console with a maximum angle of attack max docked to the console followed by propeller blades.
The proposed technical solution is illustrated graphically in Figure 1 which shows a front view of the installation, the part of the incoming wind flow, and Figure 2 - view along A-A of Figure 1, Figure 3 - view along B-B 1, .

Setting the energy supply comprises a turntable 1 (Figures 1, 2, 3) for the orientation of the apparatus in the direction of the wind flow. On the platform 1 by means of controlled-coupling sleeve 2 and 3 axis is fixed axial wind wheel with blades 4 5. On the periphery of the blade 5 integrated outer annular rim 6. In the alternating blade propeller 5 to set the direction of rotation 4 profiled twisted plane 7. Twist planes 7 is made with taking into account the direction of rotation of propeller 4. this console with the minimum angle of attack 8 min plane docked to the previous 7 9 4 blade propeller, and the console with a maximum angle of attack max 10 7 plane docked to the subsequent 11 blade propeller 4.
On the outer ring rim 6, 6a from the rear side (2, 3) has a driven rear ring 12 interacts with the drive wheels 13 of one or more generators 14 installed on pylons 15. Pylons 15 are arranged on the coupling-controlled rotary sleeve 2 platform 1. Generators 14 associated with terrestrial consumers generated electricity cables 16.
The device operates as follows.
Turntable 4 1 wind wheel installation oriented towards the wind flow. Controlled Coupling hub 2 includes a free wheeling windwheels 4. The wind flow raids on the blade 5 and profiled twisted plane 7 from the console with the minimum angle of attack 8 min console toward a maximum angle of attack max 10 generates centrifugal mass forces, which increase torque propeller 4 as a whole.
Its rotating wind wheel 4 driven ring 12 interacts with the drive wheels 13 of one or more generators 14, which generate electricity transmitted through cables 16 to the power lines of the consumer.
The annular rim 6 improves the dynamic properties of propeller 4, reducing the level of vibrations of the blades 5.
Interaction of air mass passing through the axial wind wheel 4 and twisted through the profiled plane 7, reduces vortex formation and shear for the wind wheel 4 and thus reduces noise phenomenon.
The proposed setup allows to increase the energy supply and load capacity power installation unit, and hence increases the effectiveness of such a construction reduces the unit cost of electricity generated by the device and contributes to environmental improvement.
