  • Patent number: 11333129
    Abstract: Provided is a weighing device for determining a property of a rotor blade of a wind turbine. The weighing device includes a first seat for receiving the rotor blade at a first radial position of the rotator blade, a second seat for receiving the rotor blade at a second radial position of the rotor blade, a first weight cell for quantifying a first weight which is acting on the first weight cell, a second weight cell for quantifying a second weight which is acting on the second weight cell, and a first counterweight which is configured to alleviate the first weight. Notably, the first counterweight is lifted up from the ground when the rotor blade is received by the first seat of the weighing device. Furthermore, a method of determining the weight, the mass or the torque of a rotor blade of a wind turbine is also provided.

  • Patent number: 11187204
    Abstract: Provided is a method for fabrication of a profile for a spar cap for a wind turbine blade, wherein the profile is fabricated in a pultruding process using one or more strands and/or layers of unidirectional fibres or rovings of unidirectional fibres arranged along a longitudinal direction of the profile and a tool for moulding of the fibres, wherein one or more additional fibres or rovings of additional fibres are introduced in the pultruding process prior to the moulding, wherein the additional fibres are arranged under an angle to the unidirectional fibres, and/or wherein one or more surficial fibres or rovings of surficial fibres are introduced in the pultruding process after the moulding, wherein the surficial fibres are arranged on the outer surface of the moulded profile.

  • Publication number: 20100242598
    Abstract: A root-end of the blade is connectable to a fixation unit which is pivotably mounted around a first reference-point. A first static moment of the fixation unit without the blade connected is determined in reference to a first reference-point, while the first static-moment is acting on the fixation-unit at the first distance. A second static-moment of the fixation unit and the connected blade is determined at a second distance in reference to the first reference-point, while the second distance is allocated to a cross-section of the blade. The first and the second static-moment are used to calculate the static-moment of the blade.
