<p>A wind collector blade (52) of a wind turbine has bearing surfaces (56), preferably at its extremities. Within the circle covered by the wind collector blade (52) a joint (60) arranged on the bearing surface (56) is secured to a rotor arm (62). The joint (60) is arranged in front of, in the area of or behind the profile point (58) of the wind collector blade (52), in particular depending on the weight of the wind collector blade (52). A compensating weight (66) is arranged on the bearing surface (56) in front of the profile point of the wind collector blade (52), seen in the direction of rotation. This self-adjusting compensating weight (66) compensates for the influence of the shape of the wind collector blade, the centrifugal force, the lift and the resistance to the air of the rotating wind collector blade.</p> |
