    Abstract: A noise reduction element extends between a first end and a second end in a first direction. The noise reduction element extends between a third end and a fourth end in a second direction perpendicular to the first direction. The noise reduction element includes a base part configured to be attached to a trailing edge of a wind turbine blade. The base part has a first base part surface and a second base part surface. The base part extends between the first end and a first position in the first direction. The noise reduction element includes a first serration part having a serration pressure surface and a serration suction surface and extending in the first direction between the first position and the second end. The first serration part has a thickness in a third direction between the serration pressure surface and the serration suction surface.

    Abstract: The invention relates to a wind turbine blade being a shell body made of a composite material and having a root end and a tip end, an outer surface, a pressure side and a suction side, a trailing edge and a leading edge, and additionally a lightning protection system. The lightning protection system comprising at least one lightning receptor provided with an outer surface arranged freely accessible in, on or at the outer surface of the blade at the tip end of the blade and a lightning conductor made of electrically conductive material extending within the shell body along substantially the entire longitudinal direction of the blade. The lightning receptor and the lightning conductor are electrically connected by means of a connection area. At least a part of the outer surface, optionally the whole of the outer surface of the receptor being freely accessible is formed of carbon such as graphite.
