To increase the efficiency, an auxiliary rotor (1) is mounted adjacent to the convex side of each blade (3) of the main rotor, whereby the auxiliary rotors (1) are designed in the manner of Savonius rotors and wherein the wings (15) of the auxiliary rotors (15) 1) are curved in the opposite direction as the wings (3) of the main rotor. Preferably, the auxiliary rotors (1) are provided with a cover (5) opposite the convex side of the part-cylindrical wing (3) beside which they are attached, so that two gaps (6, 7) between the cover (5) and the wing (3), wherein the gap (6) on the outside of the wing (3) is narrower than the farther inward gap (7). As a result, the air flow over a large area on the adjacent wing (3) of the main rotor is directed (arrow 20).

    The present invention relates to a wind turbine module having a main rotor with an axis from which protrude a plurality of part-cylindrical wings, wherein the generatrices of the part-cylindrical wings are parallel to the axis of the main rotor and all wings are curved in the same direction.
    Such rotors are named " Savonius rotor " were patented by Savonius some 90 years ago, see e.g. AT 103819, especially Fig. 2. Since the wings are all curved in the same direction, e.g. all the wings have the convex side in the clockwise direction (as shown in Fig. 2 of AT 103819), the wind resistance in the wing whose convex side faces the wind is lower than the wind resistance in the opposite wing where the concave side faces the wind shows. The Savonius rotor therefore rotates in the direction in which the convex side of the wings points, in this example thus in a clockwise direction (arrow r).
    It is an object of the present invention to better exploit the wind energy through such a rotor. As a result, the output at a given size power, so the power output can be significantly increased.
    This object is achieved by a wind turbine module of the aforementioned type according to the invention that adjacent to the convex side of each blade of the main rotor, an auxiliary rotor is mounted, wherein the auxiliary rotors an axis from which protrude a plurality of part-cylindrical wings, wherein the axis of the auxiliary rotors and the generatrices of their part-cylindrical vanes are parallel to the axis of the main rotor and wherein the part-cylindrical vanes of the auxiliary rotors are oppositely curved like the part-cylindrical vanes of the main rotor and wherein the auxiliary rotors have a smaller diameter than the main rotor.
    The inventively provided auxiliary rotors, which are smaller Savonius rotors, thus rotate in the opposite direction as the main rotor. They thereby accelerate the wind flow, and the wind current is guided in the direction of rotation 2/9 2 on the concave side of the next curved wing of the main rotor, whereby there the pressure and thus the torque of the entire main rotor can be increased.
    Preferably, the auxiliary rotors are provided within and immediately adjacent to the outer contour of the main rotor. The auxiliary rotors should not project on the one hand, so that the diameter of the main rotor is not unnecessarily increased, but they should on the other hand as far outside as possible, so that the wind power is deflected as early as possible.
    It is expedient if the auxiliary rotors are provided with a cover opposite the convex side of the part-cylindrical wing, next to which they are attached, so that two gaps are created between the cover and the wing. In this way, the wings, which move with the convex side ahead against the wind direction, shielded from the wind, so that the efficiency of the auxiliary rotors increases.
    It is expedient if the gap on the outside of the wing is narrower than the gap lying further inside. The auxiliary rotors with the covers are thus arranged so that the inflow of the wind stream narrows through the outer gap and the outflow of the wind is expanded by the farther inside gap so that the largest possible contact of the air flow can take place on the adjacent wing.
    Finally, it is expedient if the wings of the main rotor and the auxiliary rotors are provided with a honeycomb structure. This results in an increased Windanströmungsfläche, and the wind energy can be better transmitted to the rotor. In combination, this results in optimal wind energy utilization.
    The invention will now be further explained with reference to an embodiment, which is shown schematically in the drawing. Fig. 1 shows a cross section through an inventive wind power module. 3/9 3
    The main rotor has an axis 11, project from the wing 3, in the embodiment, five wings 3 are provided. These wings 3 are formed part-cylindrical, i. they have a concave and a convex side. The axis or generatrix of the sub-cylinders is parallel to the axis 11 (normal to the drawing plane). It does not necessarily have to be circular cylinders. Usually, a circular disk 12 is provided at the ends of the rotor. Since the convex side of the wings 3 is clockwise forward, the main rotor rotates clockwise as indicated by arrow 13 when it is flowed by a wind, the wind direction with a vertically disposed axis 11 is indifferent.
    In order to increase the effectiveness, an auxiliary rotor 1 is mounted adjacent to the convex side of each blade 3 of the main rotor and within and immediately adjacent to the outer contour of the main rotor. In the exemplary embodiment, therefore, there are five auxiliary rotors 1. The auxiliary rotors 1 each have an axis 14, protrude from the more part-cylindrical wings 15. The axis 14 of the auxiliary rotors 1 and the generatrices of their part-cylindrical wings 15 are parallel to the axis 11 of the main rotor, that is normal to the plane of the drawing. The part-cylindrical wings 15 of the auxiliary rotors 1 are oppositely curved as the part-cylindrical wings 3 of the main rotor. The auxiliary rotors 1 thus rotate counterclockwise according to arrow 16 when they are flown by the wind. The auxiliary rotors 1 have a significantly smaller diameter than the main rotor, so that between the auxiliary rotors 1 and the concave side of the adjacent wing, a gap 17 remains free, which is about the same width as the auxiliary rotor. 1
    Each auxiliary rotor 1 is provided with a cover 5 opposite to the convex side of the part-cylindrical wing 3 adjacent to which it is attached, so that two gaps 6, 7 result between the cover 5 and the wing 3, the gap 6 on the outside of the Wing 3 is smaller than the farther inside gap 7. 4/9 4
    If wind comes from the right, then the wing provided with the reference numeral 3 is flown by the direct wind at an unfavorable angle (arrow 19). The wind, which flows through the gaps 6 and 7, but is deflected by the auxiliary rotor 1 and hits at a much more favorable angle to the wing 3, as can be seen by the arrow 20. Thus, the wing 3 is already effective before it is optimal for the wind.
    To further increase the effectiveness, the wings 3, 15 of the main rotor and the auxiliary rotors 1 are provided with a honeycomb structure 4.
