FIELD: engines and pumps.
SUBSTANCE: invention relates to wind power engineering, particularly to windmills with rotary cylinders exploiting Magnus effect. Proposed windmill comprises horizontal axis wind wheel and radially arranged cylinder-type Magnus rotors, drive of cylinders and electric generator. Every rotor comprises non-rotating root part and rotating tail part, and washer arranged on its extremity. Rotor rotating part represents s cylindrical part with truncated-cone end, cone base facing the cylinder and cone diametre exceeding cylinder diametre. Note here that cylinder and cone surfaces represent spiral ribs-augers with their turning towards cylinder rotation starting from cylinder root cross section till washer.
EFFECT: reduced inductive resistance allowing notable reduction in cylinder rotational speed and power consumption as compared to traditional windmills.
