摘要
A wind turbine rotor blade that has a rotor blade tip, a rotor blade root, a suction side, a pressure side, a rotor blade length, a profile depth and a pitch axis of rotation. The profile depth decreases along the rotor blade length from the rotor blade root to the rotor blade tip. The trailing edge has a trailing edge delimiting line, which replicates the contour of the trailing edge. The trailing edge has a plurality of serrations to improve flow behaviour behavior at the trailing edge. The serrations respectively have a serration tip, two serration edges and an angle bisector. The serration edges are provided non-parallel to a direction of incident flow that is perpendicular to the pitch axis of rotation. The serration edges are non-perpendicular to a tangent to the trailing edge delimiting line. The trailing edge delimiting line has a plurality of portions, at least one of the portions extending non-parallel to the pitch axis of rotation.
