Abstract: The invention relates to a wind turbine blade (5) comprising one or more oscillation dampers (11) for damping oscillations or vibrations of the wind turbine blade (5). The dampers (11) comprise one or more first damper parts (13) having one or more first damper part surfaces (17). The first damper parts (13) being rigidly connected to the blade (5) and/or being a part of the blade (5). The dampers (11) further comprise one or more second damper parts (12) having one or more second damper part surfaces (18), wherein the first damper part surfaces (17) and the second damper part surfaces (18) are arranged to move relatively to each other during the oscillations. Even further the dampers (11) comprise a load transferring coupling (32), directly or indirectly coupling the first damper part surfaces (17) and the second damper part surfaces (18), so that the relative movement result in a oscillation-damping dissipation of kinetic energy. The invention further relates to a wind turbine (1), an oscillation damper (11), a method for damping oscillations of a wing turbine blade (5) and use hereof.

Abstract: The invention relates to a wind turbine (1) comprising at least two pitch controlled wind turbine blades (5). Each blade (5) comprise pitch bearings (9) including two or more bearing rings (24, 25, 26), and pitch controlling means for pitching the blades (5) by means of the bearings (9). The blades (5) are mounted on a hub (7) via the pitch bearings (9) and the pitch bearings (9) comprise separate flexibility enhancing means (10, 11, 12, 14, 19, 20, 28) for controlling loads in the bearings (9). The invention further relates to a use hereof.

Abstract: A method of making a wind turbine blade in a blade mould is described. The wind turbine blade comprises a plurality of elongate reinforcing structures each comprising a stack of strips of fibre-reinforced polymeric material, and the method comprises: stacking strips of fibre-reinforced polymeric material to form a plurality of stacks (40), each defining a longitudinal axis; aligning the stacks relative to one another in an alignment zone outside the blade mould; supporting the stacks to maintain their relative alignment; transferring the plurality of stacks into the blade mould simultaneously while maintaining the relative alignment of stacks as the stacks are transferred; and integrating the stacks with other blade materials forming the blade in the blade mould. An apparatus for use in the method is also described.
