Abstract: The invention relates to a leading edge protection cover for a wind turbine blade. The protection cover comprises first and second longitudinally extending edges, and outer and inner arcuate surfaces extending there between. The inner arcuate surface is shaped to be attached to an outer surface portion of the wind turbine blade such as to cover at least a part of the leading edge of the blade, and with the first longitudinally extending edge being attached to a suction side of the wind turbine blade. The protection cover further comprises a number of vortex generating members positioned on the outer arcuate surface of the protection cover along at least a part of the first longitudinally extending edge. The proposed protection cover results in an increased protection of the wind turbine blade against impacting particles and improved fluid properties over the surface of the wind turbine blade. The invention further relates to a method of preparing a wind turbine blade with a leading edge protection cover, comprising the steps of moulding a leading edge protection cover comprising a number of vortex generating members and attaching the leading edge protection cover to an outer surface portion of the wind turbine blade.

Abstract: The invention relates to a method of preparing a wind turbine blade with a leading edge protection. The method includes applying a first layer of paint on the surface portion comprising the part of the leading edge to be protected, applying a layer of a fibrous material on top of the first layer of paint, applying a second layer of paint on the layer of fibrous material, and allowing the applied leading edge protection to cure. The method may be performed as a part of the manufacture of the blade and/or as a post-processing step for example during repair on site. The proposed method results in an increased erosion resistance and improved protection against impacting particles. The invention further relates to a wind turbine blade comprising a leading edge protection established as mentioned above.
