Abstract:
The invention relates to a wind turbine rotor blade comprising a blade tip and a lightning protection system. The blade includes at least one metallic lightning receptor at the surface of the blade in proximity of the distal end of the blade tip. The blade comprises a blade shell configured partly by a fibre-reinforced laminate, and the blade also comprises an electrically down-conducting element in the form of a metallic mesh. The electrically down-conducting element extends only to a certain distance from the distal end of the tip of the blade, said distance being larger than a distance between the position of the lightning receptor and the distal end of the tip of the blade. It is hereby ensured that a stroke of lightning will strike the receptor more likely than the electrically down-conducting element.
