Abstract
The invention relates to a wind turbine generator with rotor blades being pitchably mounted, and a hub for connecting the rotor blades with the rotation shaft. The hub further comprises a plurality of radially extending support structures, a plurality of inclined support beams, one inclined support beam for each rotor blade, and/or at least a first peripheral support rod positioned in an exterior position on the hub, said first peripheral support rod connecting two of said radially extending support structures. The rotation axis for each pitchable rotor blade has a radial offset relative to the rotation shaft. The invention is thereby advantageous for obtaining a wind turbine where the resonances of the rotor blades may be controlled, i.e. shifted and/or reduced, by designing and dimensioning the plurality of inclined support beams and/or the first peripheral support rod accordingly.
