Abstract: A wind turbine blade comprising a main blade portion having a root end and a tip end, wherein a leading edge and a trailing edge extend between the root end and the tip end, and a conductive blade tip module that abuts the tip end of the main blade portion; wherein the conductive blade tip module comprises an elongate body defining a longitudinal axis transverse to a spanwise axis of the blade, and wherein the conductive blade tip module has a length in a direction along said longitudinal axis that is greater than a chord length of the blade tip interface.

Abstract: A wind turbine blade comprising a main blade portion having a longitudinal axis that extends between a root end and a tip end, wherein a leading edge and a trailing edge extend between the root end and the tip end, and a conductive blade tip module mounted to the tip end of the main blade portion; wherein the tip end is truncated and has a blade tip interface that defines an outer edge, and wherein the blade tip module is configured to fit against the blade tip interface such that a lip of the blade tip module overlaps the outer edge of the blade tip interface. Since the blade tip module is configured to overlap the tip edge of the blade, this protects the junction between the two components from erosion due to weathering.

Abstract: The present invention relates to a method of manufacturing a laminated composite part from a number of layers of resin-preimpregnated fibres (1) which are placed on a moulding surface (2). At least one breather layer (5) is then placed over at least a part of the layers of resin-preimpregnated fibres (1). The breather layer (5) has a structure comprising at least one strand or string (9) arranged in a repeated pattern in order to provide a network of interconnected channels (11), said channels (11) extending in at least two non-parallel directions within the breather layer (5) and having a cross sectional area which is at least corresponding to a thickness of the strand or string (9).

Abstract: A wind turbine includes one or more oscillation dampers, each damper having one or more closed cavities arranged within a blade of the wind turbine and containing a large number of solid elements that are arranged to move freely within the cavities.
