Abstract: A wind turbine blade (10, 610) for a rotor of a wind turbine (2) having a substantially horizontal rotor shaft is described. A surface mounted device (70, 70′, 170, 270, 370, 470, 570, 670, 770) is attached to a surface of the wind turbine blade (10). The surface mounted device (70, 70′, 170, 270, 370, 470, 570, 670, 770) is attached to the surface of the wind turbine blade (10, 610) via at least a first attachment part (77, 77′), which is connected to a part of the surface mounted device (70, 70′, 170, 270, 370, 470, 570, 670, 770). The attachment part (77, 77′) comprises a flexible housing (80, 80′, 680, 780) that forms a cavity (81, 81′, 681, 781) between at least the housing (80, 80′, 680, 780) and the surface of the wind turbine blade (10, 610). The cavity (80, 80′, 680, 780) is filled with an adhesive that provides an adhesive bonding to the surface of the wind turbine blade (10, 610).

Abstract: A method of manufacturing a fibre-composite article is described, wherein a layer of fibre material is applied from a layup head to a mould along a layup path. The angle at which the fibre material is dispensed from the layup head is rotated relative to the angle of orientation of the layup path, to minimise the effects of gravity on the alignment of the fibre layer in the mould. The fibre-composite article is preferably a section of a blade for a wind turbine.

Abstract: A flexible aeroshell extender piece for an inboard part of a wind turbine blade is described, along with an associated method of manufacture. The flexible aeroshell is formed by first assembling a consolidated aeroshell piece, and then making a series of slits at the trailing edge of the aeroshell piece. Such a construction provides an aeroshell having a relatively flexible trailing edge section, which allows for bending or flexing of the aeroshell trailing edge during wind turbine blade operation.

Abstract: The invention relates to a wind turbine blade having a leading edge erosion shield. The erosion shield comprises an inner layer of a first thermoplastic material, the inner layer being an integral part of the shell body of the wind turbine blade. The erosion shield further comprises an outer layer of a second thermoplastic material attached to the inner layer.

Abstract: Methods for manufacturing a wind turbine blade component using a layup head for automatic or semi-automatic layup of fibre material as ply sections from respective rolls of a plurality of rolls in a blade component mould are described. The methods generally include: defining a list of ply sections for the blade component including the layup sequence and length of each ply section; generating a selection of layup plans using the list, a subset of the plurality of rolls and the initial lengths of fiber material on the rolls; selecting one layup plan in constraint of at least one criterion, such as optimisation of the remaining amount of fibre material waste on the plurality of rolls in a length direction, and controlling the layup head and plurality of rolls to perform the selected layup plan in manufacturing of the blade component in the blade component mould.

Abstract: A wind turbine blade (10) is described having a serrated trailing edge (20). Splitter plates (106) are provided on the blade, to reduce operational noise. Each splitter plate (106) is arranged to extend at least partly into a space in between adjacent serrations. The splitter plates can be formed integrally with the serrations, or attached to existing serrations as a retrofit solution. The serrations with the splitter plates can be provided as a trailing edge panel (108) for attachment to the trailing edge of an existing wind turbine blade.
