    Abstract: The invention relates to a wind turbine blade comprising a blade body, a device for modifying the aerodynamic surface or shape of the blade and movably connected hereto, and operating mechanisms for controlling the position and/or movement of the device. The operating mechanism comprises a compressible pressure chamber arranged in relation to the blade body and the movable device such that the position and/or movement of the device relative to the blade body can be modified by changing the pressure in the pressure chamber thereby causing a change of its cross sectional diameter. The operating mechanisms may be connected to and driven by a pressure reservoir arranged within the wind turbine blade or for example constituted by parts of the blade spar.

    Abstract: A reinforcing structure 9 for a wind turbine blade is in the form of an elongate stack 27 of layers 31 of pultruded fibrous composite strips supported within a U-shaped channel 28. The length of each layer 31 is slightly different to create a taper at the ends of the stack; the centre of the stack 27 has five layers 31, and each end has a single layer 31. The ends of each layer 31 are chamfered, and the stack is coated with a thin flexible pultruded fibrous composite strip 33 extending the full length of the stack 27. The reinforcing structure 9 extends along a curved path within the outer shell of the blade. During configuration of the blade components within a mould 37, the reinforcing structure 9 is introduced into the mould 37 by sliding the channel 28 along the surface of an elongate wedge 29 within the mould 37 along the curved path. The wedge 29 is oriented along its length at an angle depending on the curvature of the path at that position so as to guide the reinforcing structure 9 into the desired position. The regions of the outer shell of the blade on either side of the reinforcing structure 9 are filled with structural foam 17, and the reinforcing structure 9 and the foam 17 are both sandwiched between an inner skin 18 and an outer skin 19.

    Abstract: The invention relates to a wind turbine blade having at least one component formed of a fibrous composite material including two or more different types of carbon fibres having a different elastic modulus to each other. The proportions of the different types of fibres vary in the longitudinal direction of the blade such that the elastic modulus of the fibrous composite material increases towards the tip end of the blade. The two or more different types of carbon fibres may be incorporated in an inner beam and/or in the outer shell portions of the blade.
