FIELD: engines and pumps.
SUBSTANCE: invention relates to wind power engineering and can be used for production of electric or mechanical power. Windmill consists of windwheel with rotary cylinders, cylinder drive, power supply, electrical generator articulated with windwheel and device to direct windmill to counterblast. Horizontal windwheel is composed of drum with rotary discs running in bearings on fixed shaft secured at disc ends. Cylinders with drive run on their axles in said discs. Shield secured to windmill fixed shaft is located perpendicular to counterblast. Drive is composed by one motor transmitting rotation via flexible links to pulleys of cylinders located windward. In compliance with another version, cylinders drive is composed of reversible motors secured at the drum and equipped with contact current collector while extra disc with two current collecting rings is fixed at stationary axle. Note here that said rings can be composed of two semi-rings located windward and two semi-rings located leeward. Said semi-rings are connected to power supply opposite poles. Shield secured to windmill fixed shaft is located perpendicular to counterblast.
EFFECT: efficient usage of Magnus forces.
