    Abstract: A method of manufacturing a wind turbine blade shell component (38) is provided, the method comprising arranging a plurality of pultrusion plates (64) on a blade shell material (89) in a mould (77) for the blade shell component. The pultrusion plates (64) are bonded with the blade shell material to form the blade shell component, wherein each pultrusion plate (64) is formed of a pultrusion fibre material comprising a glass fibre material (70) and a carbon fibre material (68), wherein carbon fibre material is provided along the entire lateral surfaces (83, 84) of the pultrusion plate. The glass fibre material is selected from a glass fibre fabric, a glass fibre preform comprising a consolidated arrangement of glass fibres and a binding agent, and a plurality of glass fibres encapsulated by a veil or a foil.

    Abstract: The present disclosure relates to devices for wind turbine blades and methods for reducing vibrations in wind turbines. More particularly, the present disclosure relates to devices for mitigating vortex induced vibrations and stall induced vibrations, wind turbine blades comprising such devices, and methods for reducing wind turbine vibrations when the wind turbine is parked, especially during wind turbine installation and/or maintenance. A method for mitigating vibrations of a parked wind turbine comprises arranging a device in an inactive state with a wind turbine blade; and causing the device to transition to an active state in which the device grips the wind turbine blade more strongly than in the inactive state.

    Abstract: The present invention provides a method for trimming a side portion of a pre-manufactured leading-edge protection element for a wind turbine blade. The element comprises a first side portion and a second side portion, the first side portion, when mounted to the wind turbine blade, extending from the leading edge and along a part of a pressure side of the wind turbine blade, and the second side portion, when mounted to the wind turbine blade, extending from the leading edge and along a part of a suction side of the wind turbine blade, or vice versa. The method comprises steps of: providing a support structure and a first cutting tool; arranging element on the support structure and fixating the element to the support structure, and cutting along a predetermined cutting path, whereby the leading-edge protection element is trimmed to a predetermined length. A corresponding system is also provided.

    Abstract: A method of forming a rotor blade includes positioning first dry skin layer(s) in a first mold. The method also includes placing a wedge-shaped core material having a mounting surface atop the first dry skin(s) in the first mold at a trailing edge end of the rotor blade. The method further includes infusing the first dry skin layer(s) and the core material together via a resin material to form a first shell member. The method includes applying an adhesive onto the mounting surface and then placing a second mold with a second shell member arranged therein atop the first mold containing the first shell member to form the rotor blade such that a portion of the second shell member rests atop the mounting surface. Thus, the method includes securing the shell members together via the adhesive, wherein the core material supports the trailing edge end of the rotor blade.
