Abstract
Изобретение позвол ет повысить коэффициент использовани энергии ветра вет- роколесом со ступицей 1 радиальными лопаст ми 2 и открылками 3. которые консольно закреплены йа концах лопастей со стороны их спинок 4 Каждый открылок сужаетс к свободному концу, сопр жен с поверхностью лопасти, перпендикул рен радиусу ветроколеса. Размер сопр жени вдоль хорды лопасти составл ет ее третью часть, размах открылка - 0,18-0,22 радиуса R степень сужени открылка равна 3-4. Это в совокупности позвол ет снизить индуктивное аэродинамическое сопротивление лопастей, создать в зоне их спинок области разр жени , в результате чего вовлечь в процесс преобразовани энергии дополнительные массы воздуха и повысить эффективность этого процесса 3 илThe invention allows to increase the utilization of wind energy by a wind-wheel with hub 1 by radial blades 2 and wing 3. Which are cantilever fixed at the ends of the blades on the side of their backs 4 Each opener tapers to the free end, perpendicular to the wind wheel radius . The size of the conjugation along the blade chord is its third part, the sweep of the wing — 0.18–0.22 of radius R; the degree of narrowing of the blade — is 3-4. This together allows to reduce the inductive aerodynamic resistance of the blades, to create in the area of their backs the discharge area, as a result, to involve additional air masses in the energy conversion process and to increase the efficiency of this process 3 or more
