<p>The present invention relates to a wing for a wind turbine having one or more wings mounted in a rotor, wherein the wing is provided with a certain rigidity in flap-wise direction and with a predetermined mass distribution in the wing for straightening of the wing by its rotation as the wing is provided with one or more mass concentrations in the wing tip or in its vicinity. Hereby, a straightening force perpendicular on the rotor plane is achieved, which may eliminate the flap-wise moment of the wing. This results in a reduction in the demand for the rigidity of the wings and their overall weight may be reduced.</p> |
