Speed of blades of no more than 150 rpm at any wind speed. This is accomplished by particular apparatus features. To reduce noise, increase torque and ensure the safety of birds, the rotating rotor is closed by the stator grille.

The problem with the birds and the low frequency noise radiation is particularly acute in common designs oh horizontal wind turbines.

The power generator is located at the bottom, which provides a low center of gravity and alleviates installation and maintenance – makes it easy to install on building roofs any shape, it is also possible to mount on the wall of a multi-storey building.

Does not require distance protection.

The tests took place in the suburbs of St. Petersburg for almost 5 years. The installation height above the ground is 7 meters. there were no wind-shading obstacles within 300 metres. The average annual wind speed was about 5 m/s .

The capacity of the installed generator in the first year and a half was 500W, while the average annual electricity generation was 110 W/h.

Then the generator was replaced by a less powerful 300W. which worked for 3.5 years and the average annualelectricity generation was 152 W / h. The increase in the productivity of the plant was due to the reduction of resistance and increase in the total working time in low-speed winds.
