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: The present invention provides an apparatus and a method for preparing a pre-form (2) comprising at least one layer of fibre tows being at least partly fixed by a resin. The apparatus comprises a work surface (3), a fibre tow distribution device (4), a fibre tow retention device (5), and a manipulation, device (7b) which is adapted to move the fibre tow distribution device relative to the fibre tow retention device. The apparatus is arranged so that free ends of the fibre tows can be delivered from the fibre tow distribution device to the fibre tow retention device, and the fibre tow retention device is adapted for retention of the free ends so that mutual movement of the fibre tow distribution device and the fibre tow retention device away from each other causes drawing of the fibre tows through distribution passage and distribution hereof onto the work surface.

Abstract: The invention relates to a wind turbine rotor comprising at least one blade and at least on pitch mechanism comprising a ring shaped motor for controlling the blade. The wind turbine rotor is characterized in that, the ring shaped motor controls the blade through gearing means of a planetary type. The invention further relates to a rotation controlling mechanism comprising, at least one ring shaped motor for controlling the rotation of at least one first part in relation to at least one second part. The rotation controlling mechanism is characterized in that, the ring shaped motor controls the relative rotation through gearing means of a planetary type. Even further the invention relates to a method for controlling at least one blade of a wind turbine rotor.

Abstract: A connection between composites (10, 12) with non-compatible properties and a method of preparing of such connections are provided. The composites comprise first and second type fibres, respectively, as well as resin. The connection comprises a transition zone (52) between the composites (10, 12) having a layered structure. The transition zone may optionally comprise a transition member and the transition member may optionally be integrated with one or more of the composites. Examples of non-compatible properties where the present connection will be appreciated are great differences in stiffness, e.g. Young's modulus, or in coefficient of thermal expansion.
