Abstract
The present invention relates to a wind turbine generator with a hub that has a plurality of radially extending support structures, one radially extending support structure for each rotor blade, and a plurality of inclined support beams, one inclined support beam for each rotor blade, and/or 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 inclined support beams, and/or the first peripheral support rod have an airfoil shape providing aerodynamic lift upon wind engagement. This is advantageous for obtaining a wind turbine where the rotor blades resonances are controlled by designing and dimensioning the plurality of inclined support beams and the first peripheral support rod accordingly. At the same time the volume of the hub is utilized for increasing the aerodynamic lift while still facilitating a relatively strong structure of the hub.
