Abstract: A method is presented that reduces vibrations of a wind turbine in a situation where yawing of a wind rotor of said wind turbine is at least temporarily not possible. The method includes adjusting a first pitch angle of a first rotor blade and a second pitch angle of a second rotor blade such that the first and second pitch angles differ by at least 30 degrees.

Abstract: A method for assembling a modular wind turbine rotor blade, includes aligning a first blade module and a second blade module such that a first receptacle of the first blade module and a second receptacle of the second blade module are co-axial; and forming a detachable mechanical connection between a first inlay of the first blade module and a second inlay of the second blade module using a threaded fastener that extends into the first receptacle and into the second receptacle.

Abstract: A blade module of a modular rotor blade comprising a hollow fiber composite body which extends along a longitudinal blade axis and at least one inlay located at or near a longitudinal end of the fiber composite body is provided. The inlay includes a receptacle which is adapted to receive a threaded fastener and an anchoring portion anchored to the fiber composite body. Further, a modular wind turbine rotor blade which includes at least two blade modules and a method for assembling a modular wind turbine rotor blade are provided.
