Abstract: Wind Turbine Blade (12) Leading Edge (24, 30, 88) Protection Method In a first aspect of the invention there is provided a method of applying an erosion shield (22) to a leading edge region (30) of a wind turbine blade (12). The method comprises providing a wind turbine blade (12) comprising a blade shell (26) having an aerodynamic profile and defining a leading edge region (30); providing an erosion shield (22) made of a polymer material, the erosion shield (22) having an inner surface (36) to be bonded to the leading edge region (30) of the blade shell (26), and an outer surface (38, 84, 98) to be exposed in use; activating (44) the inner surface (36) of the erosion shield (22), and cleaning (42) the inner surface (36) of the erosion shield (22) using a solvent.

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.

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.
