<p>This invention relates to a wind turbine blade with at least two connection members such as bushings and/or threaded bars in the root of said blade for attaching said blade to a hub. The connection members are placed along the blade surface and at least some of said connection members are non-parallel and hence oriented in different directions. Hereby is obtained that the root section of the blade can be shortened and the maximum chord of the wind turbine blade can be moved closer to the hub, whereby the part of the blade exploiting the wind is increased and the power output similarly increased. The present invention further relates to a pitch bearing and a hub comprising a bearing ring with two or more holes for positioning fastening members for attaching a wind turbine blade to the bearing. Here, correspondingly, at least two of said holes are oriented in different angles so that the fastening members positioned in the holes are non-parallel and extend in different directions.</p> |
