FIELD: power engineering.
SUBSTANCE: invention relates to wind and hydraulic power industry. Wind and hydraulic power unit with composite blades, using Magnus effect in flow, contains wind and hydraulic impeller with horizontal rotation axis, at which electric generator is fixed, and cylinders with drive radially mounted on flaps, on one end each cylinder has non-rotating root part, on other is rotating end part, equipped with washer, truncated cone, and contains spiral ribs-screws on its surface and on cone surface, wherein cone base faces cylinder, which diameter is larger than diameter of cylinder. On cylinders both sides on flaps brackets are secured with possibility of turning, between brackets along flow direction axis rotors are located, of Savonius type, wherein rotors are located in front of or behind cylinders, and their blades are installed on matched with cylinders rotation direction.
EFFECT: invention aims at increasing of aerodynamic lift in working cylinders based on Magnus effect.
