FIELD: wind power engineering.
SUBSTANCE: invention relates to designing of windmill blades. In proposed rotary windmill with vertical axle of rotation, blades of rotor, guide bell to direct wind flow to face surface of blade and wind vane, blades of rotor are made with profile formed by parabola Y1=K1X1/2 where K1≥0.7. To reduce free oscillations, rotor blades are mechanically closed over circumference.
EFFECT: improved efficiency of windmill.
