Abstract:
A wind turbine includes rotor blades pivotably mounted in a gondola such that the pitch of the blades is adjustable, and pitch adjustment mounted coaxially and pivotably on the rotor axle such that the pitch adjustment are rotatable relative to that axle. The gondola is furthermore connected via torsion positioning to the axle, such that it can rotate relative to the pitch adjustment to adjust the pitch of the rotor blades. The wind turbine may also include a cable for each rotor blade, which are each with one end connected to the blade and with their opposite end to the rotor axle, such that the blades are supported by the cables against movement in the radially outward direction.
