description The invention relates to the windmills, in particular to a helical turbine, the axis of rotation of which coincides with the wind direction.The wind helical turbine contains an axle (1), onto which there are rigidly fixed following the helical line with a constant step the blades (2), having in the normal section the wing-profile. In order to reduce the wind retardation in the turbines of a greater length the blades can be installed with different step of the helical line, namely with increase towards the outlet of the turbine.The result consists in increasing the utilization coefficient of the wind energy due to the air speed difference onto the two surfaces of the blade and in the efficient functioning at small wind velocities. Invenţia se referă la motoarele eoliene, în special la o turbină elicoidală, axa de rotaţie a căreia coincide cu direcţia vântului.Turbina elicoidală de vânt conţine axul (1), pe care sunt fixate rigid pe linie elicoidală cu pas constant paletele (2), care au în secţiune normală profil-aripă. Pentru reducerea frânării vântului în turbinele de o lungime mai mare paletele pot fi instalate cu pas diferit al liniei elicoidale, şi anume cu majorare spre ieşirea din turbină.Rezultatul constă în majorarea coeficientului de utilizare a energiei vântului datorită diferenţei vitezelor aerului pe cele două suprafeţe ale paletei şi în funcţionarea eficientă la viteze mici ale vântului. Изобретение относится к ветряным двигателям, в частности к винтовой турбине, ось вращения которой совпадает с направлением ветра.Ветряная винтовая турбина содержит вал (1) на котором по винтовой линии с постоянным шагом жестко закреплены лопасти (2), имеющие в нормальном сечении форму крыла. Для уменьшения торможения ветра в турбинах большей длины лопасти могут быть установлены с разным шагом винтовой линии, а именно с его увеличением к выходу из турбины.Результат состоит в повышении коэффициента использования энергии ветра благодаря разности скоростей воздуха на одной и другой поверхностях лопасти и в более эффективном функционировании при малых скоростях ветра.
