Abstract

Изобретение позвол ет повысить коэффициент использовани  энергии ветра. Перо имеет в поперечном сечении вид обтекаемого профил  с отогнутым носком 2 на наветренной стороне, с подветренной стороны профиль выполнен в виде эллипсоида вращени , а с наветренной стороны - в виде кривой, описываемой функцией плотности логарифмически нормального распределени . Благодар  выемке с наветренной стороны давление в хвостовой части лопасти становитс  меньше, чем в носовой части. Давление потока циркул ции на выступ увеличиваетс , что позвол ет получить больше энергии из потока и тем самым повысить коэффициент использовани  энергии ветра. 3 ил.The invention makes it possible to increase the utilization of wind energy. The feather has a cross-sectional view of a streamlined profile with a bent toe 2 on the windward side, on the leeward side, the profile is designed as an ellipsoid of rotation, and on the windward side, as a curve described by the density function of a log-normal distribution. Due to a notch on the windward side, the pressure in the tail section of the blade becomes less than in the nose section. The pressure of the circulation flow to the protrusion increases, which allows more energy to be obtained from the flow and thereby increase the utilization of wind energy. 3 il.
