ABSTRACT:
A wind-driven power plant comprising at least one rotor having a gyration axis, a base, a carrier construction pivotable on said base about an upstanding axis, a support structure pivotable on said carrier construction about a tilt axis in a manner permitting precession of said rotor, said rotor being rotatably supported by said support structure and rotatable about said gyration axis, an adjusting device for pivoting said carrier construction on said base in response to changes in horizontal wind direction, a setting device for exerting torque directly or indirectly on the rotor gyration axis or on the rotor which has a torque vector component extending perpendicularly to the rotor gyration axis and perpendicularly to the upstanding axis, said tilt axis intersecting both the rotor gyration axis and the upstanding axis and forming an angle with both, and a control device for controlling the magnitude of movement of said adjusting and setting devices in response to the rotor rotational speed and the desired wind direction orientation to be exerted on the rotor in accordance with the torque to be exerted by the upstanding axis adjusting device and in compliance with the laws of gyroscopic precession.
