The postindustrial society has relied on renewable energy sources, which include wind energy. Wind generators of a propeller-type with horizontal axis of rotation are mostly used. Such generators need powerful carrying towers with expensive foundations, which extends the payback time. Moreover, such aggregates are powerful low-frequency sources of noise. These circumstances limit the number of customers and compel to search an alternative to traditional wind generators. 

The newly created wind turbine is a vertical axis wind turbine (international abbreviation is VAWT) of a carousel type. Vertical axis wind turbines have become a modern trend. They are noiseless and do not need large investments. Moreover, they are easier and cheaper than horizontal axis turbines. The prospects of vertical axis wind turbines are confirmed even by the fact that at the 8th World wind energy conference held in Canada in June 2008 on section “Construction of wind turbines” all reports (from the USA, Canada, Saudi Arabia, etc.) were devoted to such wind generators.

While horizontal axis rotors are switched to a protective mode of autorotation at a certain full wind speed, the excess of which is fraught with the structural failure. In this mode the propeller is disconnected from the multiplier and the generator, electric energy is not produced. And vertical axis rotors suffer much less mechanical stress than horizontal axis rotors at the same wind speed. In addition, the latter require expensive position control systems with the wind.

There is still no general theory of vertical axis turbines. The disadvantage of these systems is considered to be the wind energy efficiency, which is about one third of the wind energy in the rotor pack. This refers to allegedly the most perfect of them – Darrieus wind turbines proposed in 1926. Over the past century there were nuclear-powered aircraft carriers, space air drones and smart watch. But what prevents from surpassing the turbines of the late monsieur Darrieus? Are not the reasons why venerable scientists denied the right to exist heavier-than-air vehicle in the 19th century? It seems that they are.

As for technical efficiency, our prototype with a blade height of 800 mm at a wind speed of 11 m/s has developed a mechanical power of 225 W (at 75 rpm). At the same time, it stood at a height of less than a meter above the surface. According to the resource, the comparable power (300 W) is developed by a five-lobed vertical wind generator mounted on a six-meter mast, and it has five 1200-mm lobes installed at an overall diameter of 2,000 mm. So, if we take wind-blown areas of comparable wind generators to be equal, it turns out that the prototype is more energy efficient than the known wind generator by a factor of 2.5-3, considering the fact that there is a weaker wind near the ground, and it has a pronounced turbulent character. Therefrom, knowing that the described analogue has the wind energy efficiency of 0.2, it is possible to estimate the wind energy efficiency as 0.48, which is much higher than for the Savonius and Darrieus VAWT, and corresponds to the best world patterns of horizontal axis wind generators.

In this case, the material consumption and prime cost of the prototype is incomparably lower than for propeller mast wind generators, which have wind orientation mechanisms and a highly located energy module with an expensive planetary-type increaser.
