The wind turbine comprises a shaft (1) arranged perpendicularly with respect to the wind direction according to a vertical, horizontal or inclined axis. Flettner rotors (2) are fixed on the spokes (3) or along the periphery (4) of the wind turbine. These Flettner rotors (2) transform the transverse generated by the Magnus effect into a rotation force of the wind turbine. The Flettner rotors (2) which are provided preferably with end disks, are driven by electrical motors or by Savonius rotors. On the leeward of the wind turbine, the Magnus effect is eliminated by stopping the rotation of the Flettner rotors (2) or by taking them away from the action of the wind by a mask (5) or by other means. Thereby is provided a wind turbine which may operate with small wind speeds, of which the number of revolutions is easily adjustable to a large extent and which has a high efficiency due to the magnitude of the Magnus effect. |
