Abstract: A wind turbine blade comprising a lightning protection system is provided. The lightning protection system comprises a lightning conductor located along a longitudinal portion of the wind turbine blade and is coupled to an electrical ground. A lightning receptor module is arranged on an external surface of the wind turbine blade and electrically coupled to the lightning conductor. An elongate receptor band is installed on the external surface of the wind turbine blade, over the lightning receptor module, and the receptor band is arranged to receive a stroke of lightning and transfer electrical current from the lightning stroke to the lightning conductor through the lightning receptor module. Further, the elongate receptor band comprises a crease in a longitudinal cross-sectional profile of the elongate receptor band.A method of installing a lightning protection system on a wind turbine blade is further provided.

Abstract: The present invention relates to a fibre sheet material and method of laying up fibre sheet material to manufacture wind turbine blades. The invention further comprises a blade manufactured by the method as well as a use of such a blade. One aspect relates to an oblong fibre sheet material(26)for wind turbine blades, where a surface layer (14) is having a width, which in the lateral direction is broader than a lateral, unidirectional layer (10), and lengthwise side faces of at least the surface layer is provided with a thinning of a thickness of the layer to obtain favourable joints. Another aspect concerns manufacturing a wind turbine blade shell comprising laying fibre sheet (26) materials in a blade mould (20), where the sheet materials lengthwise are positioned in a direction corresponding to a chordwise direction of a turbine blade direction of the mould and overlapping in a spanwise direction. The effect obtained is a significant reduction in the amount of waste material compared to laying fibre sheets in the spanwise direction.

Abstract: A wind turbine including a drive train. The drive train includes at least a rotor for transforming wind into rotation of a rotor hub, to provide a drive torque, a generator for transforming at least a part of the drive torque into electrical power, and at least one coupling for connecting a first drive train component to a second drive train component for transferring the drive torque between the components. The coupling includes a first coupling part with a first coupling area, the first coupling area being connected with a second coupling area of a second coupling part, whereby the drive torque is transferred from one of the areas to the other of the areas during operation of the coupling.
