The use of the new screw developed by the author in the construction allowed tocreate a wind propulsion system, which allows three to four times increase the efficiency ofthe collection of wind power, and this in different forms. And the combination in modulardesign allows to build wind dams with any given capacity. Thus a construction of the windturbine was created that depending on the given tasks can be of different type: from a pocketversion to wind dams.

The construction of the wind turbine is based on a number of "know-how" whichallows to patent the development in leading countries of the world. The preliminary patentsearch was already carried out, which confirms the patentability of the product.

Individual wind turbine 5 kW

1. The cost of one power unit of the wind turbine was reduced 2-3 timescompared to the analogues due to increased efficiency.

2. The basis of the wind turbine is the slow-speed ring oscillator. Its princi-ple of operation - three-phase synchronous generator with contactless ex-citation from rare-earth magnets.

3. The blade of the special design is made of glass-carbon or composite by aspecial technology and has a high resource.

4. The applied eight-blade wind rotor scheme with a similar energy-conver-sion efficiency has several technical advantages:

a. Higher operating torque of the wind rotor and this means lessweight and lower price of the electric generator on 30-50%;

b. The blade is attached to the shaft of the generator at an angle, thatis the blade itself does not perceive the wind pressure on the bend,this is cheaper and more reliable.

Each wind generator can function either individually or connected to the wind millgroup to increase the performance. The modular cells of the wind mill not only give a moreflexible design, but also do not spoil the looks reminding on a three-dimensional crystallineopenwork structure. Thanks to this method of fastening of wind generators, it becomespossible to distribute the load on the whole system reducing the number of mounting basesand stretching the construction.

Since the blades occupy about 80% of the swept area, wind energy is used with anefficiency level of about 90%. Another advantage of the design on the base of conical helix isthe elimination of vibration and reverse flow, which allows to minimize the danger to birds.

There is a difference in pressure in front and behind the rotor blades of the wind mill,this leads to higher performance. Even when the wind blows at an angle of 60 degrees intothe rotor, it will start to rotate. No expensive software is required: The wind funnel directsitself automatically to the optimal wind direction based on the principle of a wind vane. Thewind turbine is almost silent.

The productivity of 1 Wind turbine is annual electricity collection of 260,000 kWh/year.

Modular and monolithic structures are made of folded shells of convex or concaveform on the basis of unification of elementary shells. As the basis for unification were takenthe fragments of the surface of the torus with positive and negative Gaussian curvature.Thanks to two signs of curvature from elementary shells can be arranged constructions ofvarious form, the geometrical accuracy of the surface of which is provided by variousthickness of seams between shells. Prefabricated elements are connected with support ringsand among themselves by welding of mortgage parts (reinforcing editions) and grouting ofseams.

The wind turbine of a new type will reduce the cost of wind energy by 2 – 3 times.The increase in the size of the wind rotors will increase their efficiency at another 1.5 - 2times, which would reduce the cost of 1 kWh of wind energy by 3 – 6 times.

The presence of an effective wind propulsion system allows to produce wind turbines ofdifferent power and design.

When installing a modular wind mill at an altitude of 40-60 m (commercial wind) inany region of the world with weak or medium winds, the cost of producing of 1 kWh of elec-tricity will be by 2-3 times lower than the cost of obtaining energy by any diesel generator.

"Wind park"

Each wind generator can function either individually or connected to the wind mill groupto increase the performance. The modular cells of the wind mill not only give a more flexibledesign, but also do not spoil the looks reminding on a three-dimensional crystalline openworkstructure. Thanks to this method of fastening of wind generators, it becomes possible todistribute the load on the whole system reducing the number of mounting bases andstretching the construction to create a wind dam.

1. Wind turbine ("Front"), up to 500 kW, consists of 5 – 10 wind tur-bines of different power and size, its mast is in the form of a standard sup-port of a high-voltage transmission line with height of 35 m.

2. Wind turbine ("Fir"), up to 500 kW, consists of 5 – 10 wind turbinesof different power and size, its mast is in the form of a standard support withheight of 45 m.

3. Wind ("Park 1"), from 2 to 50 MW, consists of 5 – 100 wind turbines ofdifferent power and size, its mast is in form of a standard support (tower) withheight of 60 m.

"Wind dam"

The wind dam is installed individually in places with a constant wind flow in onedirection, consists of a series of "Individual" Wind turbines of modular type, connectedamong themselves in a single construction, having a common connection (electric,mechanical, hydraulic).

Page 10 of 11

The Wind dam, from 10 to 500 MW, consists of 10 – 100 modules of different power andsize, its masts are in the form of standard supports, connected in a single structure up to 60 mhigh.

A Wind dam has its own special characteristics:

Minimal windage due to the effective transformation of the wind flow (pressure) into the energy of rotation;

Density of stacking 0.9, including the module and the whole Wind park;

High efficiency, or high wind utilization level;

Uses the system of distributed coupling;

As base for the Wind park are used modules that have 7 – 9 equal wind turbinesinstalled by the hexagonal scheme (honeycomb) in volumetric execution of thebearing structure;

Stationarity, orientation to the constant wind or side.

The statistics on energy generation systems in the world convince that wind powerhas already withdrawn from the category of "alternative", becoming one of the mainareas for generation of the principal energy.
