Abstract

Przedmiotem zgłoszenia jest sposób zwiększenia sprawności turbin wiatrowych o pionowej osi obrotu, charakteryzujący się tym, że eliminuje dopływ powietrza do części turbiny pracującej pod wiatr przez co eliminuje hamowanie turbiny i zwiększa jej sprawność. Sposób zwiększenia sprawności turbin pionowych polega również na zastosowaniu osłony, która blokuje dopływ powietrza tylko do części turbiny pracującej pod wiatr i ustawiającej się za pomocą statecznika pionowego w odpowiedniej pozycji do wiatru. Przedmiotem zgłoszenia jest także ww. osłona.The subject of the application is a method of increasing the efficiency of wind turbines with a vertical axis of rotation, characterized by the fact that it eliminates the air flow to the part of the turbine working against the wind, thus eliminating the braking of the turbine and increasing its efficiency. A way to increase the efficiency of vertical turbines is also to use a cover that blocks the air flow only to the part of the turbine operating against the wind and positioned in the appropriate position towards the wind using the vertical stabilizer. The subject of the notification is also the above-mentioned cover.
