Wind power turbine combining a cross-flow rotor and a magnus rotor

A wind power plant, comprising:

• a rotor unit configured to convert wind movements into a rotational movement;
• a work device configured to convert kinetic energy of the rotational movement into work to be performed;
• and
• a gear device configured to couple the rotor unit to the work device to transmitting the rotational movement to the work device;
• wherein the rotor unit has at least one wind power hybrid rotor comprising
• a cross-flow rotor;
• a guide device;
• and
• a Magnus rotor;
• wherein the cross-flow rotor is configured rotatable about a rotational axis and has a plurality of axially extending rotor blades,
• wherein the guide device has a contiguous circular arc shaped housing segment enclosing no more than one quarter of the cross-flow rotor in a circumferential direction in such a manner that the cross-flow rotor is driveable by inflowing wind,
• wherein the Magnus rotor is configured within the cross-flow rotor so that a Magnus rotor axis extends in a direction of the rotational axis, and
• wherein the Magnus rotor has a closed lateral surface and is rotatably drivable by a drive device about the Magnus rotor axis.

A method for converting wind energy into drive energy for performing work, the method comprising the following steps:

• rotating a cross-flow rotor that is supported so as to be rotatable about a rotational axis and which has a plurality of axially extending rotor blades;
• moving a guide device having a contiguous circular arc shaped housing segment enclosing no more than one quarter of the cross-flow rotor in the circumferential direction to a position with respect to inflowing wind and the cross-flow rotor such that the cross-flow rotor is driven by the inflowing wind;
• rotating a Magnus rotor that is arranged within the cross-flow rotor and a Magnus rotor axis of which extends in a direction of the rotational axis, wherein the Magnus rotor has a closed lateral surface and is driven by a drive device about the Magnus rotor axis;
• and
• driving a work device by the cross-flow rotor,
• wherein the Magnus rotor deflects, on its lee side, air flow with respect to an inflow direction in such a manner that the air flow flowing through the cross-flow rotor acts on the rotor blades in an expanded circular arc.
