    摘要: A blade, for a rotor of a wind turbine has a profiled contour in a radial direction is divided into a root region with a substantially circular or elliptical profile closest to the hub and an airfoil region with a lift generating profile furthest away from the hub. A transition region between the root region and the airfoil region has a profile gradually changing in the radial direction from the circular or elliptical profile of the root region to the lift generating profile of the airfoil region, and the airfoil region comprises at least a first longitudinal segment extending at least 20% of a longitudinal extent of the airfoil region. The first longitudinal segment has a first base part with a cross-sectional profile such that, when impacted by an incident airflow at an angle of attack of 0 degrees has a lift coefficient, which is 0 or less.

    摘要: A blade for a rotor of a wind turbine is divided into a root region closest to the hub and an airfoil region with a lift generating profile furthest away from the hub. A transition region has a profile gradually changing in the radial direction from the circular or elliptical profile of the root region to the lift generating profile of the airfoil region, and includes at least a first longitudinal segment extending along at least 20% of a longitudinal extent of the airfoil region. A base part has an inherent non-ideal twist, such as no twist, or a reduced twist compared to a target blade twist, so that an axial induction factor of the first base part at a design point deviates from a target axial induction factor. A number of flow altering devices are arranged so as to adjust the aerodynamic properties of the first longitudinal segment.

    摘要: The present invention relates to a wind turbine blade for a rotor of a wind turbine having a substantially horizontal rotor shaft. The blade may comprise a profiled contour comprising a pressure side and a suction side as well as a leading edge and a trailing edge, a chord extending between the leading edge and the trailing edge, and the profiled contour generating a lift when being impacted by an incident airflow. In a cross section of the wind turbine blade perpendicular to a lengthwise direction of the wind turbine blade, a suction side point is defined on the suction side at the trailing edge of the blade, and a pressure side point is defined on the pressure side at the trailing edge of the blade. The suction side point is movable in relation to the pressure side point, and the blade is further provided with a displacement device configured to displace the pressure side point and the suction side point so that a distance between the suction side point and the pressure side point can be varied. The present invention further relates to a wind turbine including such a wind turbine blade and to a method of operating a wind turbine including such a wind turbine blade.

    摘要: A blade element (42; 44; 46; 48; 150; 250; 350) for mounting on a wind turbine blade (10) is provided. The blade (10) has a longitudinal direction (L) and a chord extending transversely to the longitudinal direction between a leading edge (18) and a trailing edge (20). The blade (10) has an airfoil profile with a thickness between a suction side and a pressure side along at least a part of the longitudinal direction (L) and with a position of maximum thickness between the leading edge (18) and the trailing edge (20). The blade element (10) has a shape so that, by mounting in a first longitudinal part of the wind turbine blade (10), it changes the profile of the first longitudinal part from a first airfoil profile (100; 200; 300) with an essentially pointed trailing edge (100; 200; 300) and a first chord length (c11; c21; c31) to a changed airfoil profile with a blunt trailing edge (153; 253; 353). The changed airfoil profile is a truncated profile of an imaginary airfoil profile (160; 260; 360) with an essentially pointed trailing edge and a second chord length (c12; c22; c32), which is larger than the first chord length (c11; c21; c31).

    摘要: 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 the blade for attaching the blade to a hub. The connection members are placed along the blade surface and at least some of the 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 the holes are oriented in different angles so that the fastening members positioned in the holes are non-parallel and extend in different directions.
