Abstract: A fairing for a modular blade of a wind turbine generator, comprising including a joining zone disposed between two consecutive modules of the modular blade. The fairing is comprised of different components; the suction side fairing, the pressure side fairing and auxiliary components, such as tabs to facilitate the joining of the components. The leading edge fairing and the trailing edge fairing are constituted of an elastomeric material, preferably silicone, supported in a rigid glass fibre framework in order to absorb the warping experienced by the blade during the operation thereof. The attachment elements employed to join the fairings together and to the setbacks of the blade shell are rivets or similar. All the fairings incorporate the metal elements necessary to be equipotentially bonded, being linked to the lighting down-drop.

Abstract: A repair device and method for repairing damage around the leading edge of a wind turbine blade (20) are provided. The repair device includes a robotic maintenance device (40) and an unmanned aerial vehicle (UAV) (62) that can move the maintenance device (40) between a storage position and an operation position, the former being mounted on a blade (20) of the wind turbine (10). The UAV (62) hovers and remains connected to the maintenance device (40) during operations at the blade (20) to minimize a total operational downtime needed to conduct the repair actions. The UAV (62) is secured to the maintenance device (40) by at least one support line (68) that carries the weight load of the maintenance device (40) and at least two control lines (72) that prevent undesired rotations of the maintenance device (40), thereby improving precision and accuracy of UAV-driven movements of the maintenance device (40). A transport container (24) may also be provided to define the storage position, the transport container (24) including an elongated slot (70) for guiding movement of the lines (68, 72) and the maintenance device (40) during movements into and out of a storage space within the container (24).

The method comprises providing at least a portion of a wind turbine blade shell comprising a windward surface, a leeward surface, and a leading edge, providing a leading edge mould comprising a concave curved mould surface and arranging the mould over the leading edge of the blade shell such that a generally C-shaped cavity is defined between the blade shell and the mould surface. The method further comprises clamping the mould to the windward surface and/or to the leeward surface of the blade shell using a clamping arrangement spaced from the leading edge in a chordwise direction. The method further comprises providing an edge scaling arrangement positioned between the leading edge and the clamping arrangement in the chordwise direction, and forming a seal between the mould surface and the windward and leeward surfaces of the blade shell using the edge sealing arrangement to define windward and leeward edges of the C-shaped cavity. The mould surface is substantially tangential to the windward and leeward surfaces at the windward and leeward edges such that the C-shaped cavity tapers in thickness towards the windward and leeward edges of the C-shaped cavity. The method further comprises supplying polymer to the C-shaped cavity to form a leading edge protection shield on the blade shell.
