Abstract: An apparatus, and method thereof, for tapering an edge of a fibrous reinforcement sheet 14 for a composite structure comprises a support 20 for the sheet and a cutting tool 18 capable of relative translational movement with respect to the sheet; the cutting tool being acutely angled with respect to the sheet to develop an inclined cutting plane 32. Preferably, the sheet is held 24, 34 under tension against the support and the cutting plane is substantially tangential to the supporting surface. The cutting plane may intersect the inner side of the sheet in a clearance zone adjacent the supporting sheet where there is a gap between the inner side of the sheet and the support. The gap may be provided by holding the sheet away from the support, or by a recess in the support. Cooling means 56 may be applied to the sheet through the clearance zone or the support. Preferably, the support is a convex-curved surface and the cutting tool may be an ultrasonic knife.

Abstract: A hub (1) for a wind turbine is disclosed, the hub (1) comprising a continuous shell forming an internal space within a hollow body, and the hub (1) further comprising a main shaft flange (2) adapted to connect the hub (1) to a main shaft and one or more blade flanges (3), each blade flange (3) being adapted to connect the hub (1) to a wind turbine blade. The hub (1) comprises one or more reinforcement elements connected to the shell and extending from an inner surface of the shell and inwardly into the internal space within the hollow body. This allows the regions between the blade flanges (3) to be small or narrow, thereby reducing the size and weight of the hub (1), while maintaining a sufficient strength and stiffness of these regions.

Abstract: The invention relates to a method of operating a wind turbine (1) to guard against oscillations of the wind turbine blades (5) when they are at a standstill or idling at low speeds, and to a wind turbine blade anti-oscillation apparatus (10). The apparatus comprises a releasably attachable blade cover (10) that provides a non-aerodynamic surface for a region of the blade. This has been found to prevent air flow adhering to the blade and periodically detaching in a phenomenon known as vortex shedding, and therefore prevents oscillations of the blade becoming problematic. The blade cover can comprise a sleeve (10) of a net-like material, that can be positioned on the blade either before installation or in the field by service engineers using guide lines 16 and 17.

Abstract: A method and an apparatus for producing a multiaxial fabric are disclosed. According to the method at least one yarn is arranged helically about at least two conveyor portions, thereby providing a weft having a first weft portion having yarns arranged at an angle, θ, with respect to the conveying direction of the conveyor portions, and a second weft portion having yarns arranged at an angle, -θ, with respect to the conveying direction of the conveyor portions. Centre sections of the first weft portion and the second weft portion are then fixated to each other, e.g. by stitching and/or by applying a resin to the centre sections. Side portions of the weft are then cut, thereby separating the first weft portion from the second weft portion. Finally, rim sections of the first weft portion are fixated to rim sections of the second weft portion, e.g. by stitching and/or by applying a resin to the rim sections. The combination of helically winding the yarn about the conveyor portions, fixating the centre sections to each other, cutting the side section and fixating the rim sections to each other ensures that it is not necessary to cut away material, and the material used for making the weft is therefore utilised to the greatest possible extent.

Abstract: A wind turbine with a drive train placed partly or entirely in a nacelle of the wind turbine is provided. The drive train includes an epicyclical gearbox including at least one gear stage having a plurality of planet gears meshing with a sun gear and an annulus gear. The gearbox is used to transfer and speed-up the rotation of a rotor of the wind turbine, as applied to at least one generator of the wind turbine. The drive train further includes at least one locally radial self tracking bearing for enabling the rotation of the rotor in relation to a nacelle structure of the nacelle. The self tracking bearing includes bearing elements for locally transferring loads in both radial directions between one or more bearing rings.
