Abstract: The present disclosure relates to a wind turbine blade. The wind turbine blade comprises a load carrying structure made of a fibre-reinforced polymer material. The load carrying structure comprises a plurality of stacked fibre layers or fibre mats in a thickness of the load carrying structure. The plurality of said stacked fibre layers or fibre mats are made of hybrid material comprising both carbon fibres and glass fibres and having a carbon fibre ratio. The carbon fibre ratio is defined as a volume of the carbon fibres divided by a total volume of the glass fibres and carbon fibres. At least a number of said stacked fibre layers or fibre mats have different carbon fibre ratios such that the carbon fibre ratio of fibre material varies through the thickness of the load carrying structure.

Abstract: A method of manufacturing a fibre-reinforced polymer object by means of vacuum-assisted resin transfer moulding (VARTM), wherein fibre material is impregnated with liquid resin in a mould cavity comprising a rigid mould part having a mould surface defining an outer surface of the object, is described. One or more pressure sensors are connected to resin inlets of the VARTM system. A control unit is used for controlling a polymer supply unit based on measured resin pressure and is adapted to adjusting a resin flow rate, if pressure measured by the pressure sensors is below a lower threshold level or above a higher threshold level.

Abstract: A post-molding station is described which is used in the manufacturing of a wind turbine blade. A blade shell forming part of a wind turbine blade is initially molded in a blade mold, the blade shell subsequently transferred to a post-molding station which allows for various post-molding operations to be carried out on the blade shell away from the mold, thereby increasing the productivity of the blade mold in the manufacturing process. The post-molding station may be operable to perform the closing of first and second blade shells to form a wind turbine blade, and may be formed from an adjustable structure which can provide relatively easy access to the contained blade shell for working thereon. Accordingly, the manufacturing equipment may be of reduced cost, combined with an increase in the overall productivity of the manufacturing system.

Abstract: The present invention relates to a method for controlling a wind turbine, in particular a method for controlling pitch of one or more blades of a wind turbine and related system. The method comprises collecting first data indicative of a dynamic condition of the first wind turbine blade and the rotor, the first data comprising rotor data and first deflection data, the rotor data being indicative of the azimuth position and rotational velocity of the rotor in a rotor plane perpendicular to the rotor axis, and the first deflection data being indicative of the position, speed and acceleration of one or more parts of the first wind turbine blade. Further, the method comprises calculating an expected tower clearance distance at a later time of tower passage for the first wind turbine blade based on the first data including acceleration of one or more parts of the first wind turbine blade, and performing measures to prevent tower collision, if the expected tower clearance distance fulfills a collision risk criterion.
