Abstract: A wind turbine blade (10, 610) for a rotor of a wind turbine (2) having a substantially horizontal rotor shaft is described. A surface mounted device (70, 70′, 170, 270, 370, 470, 570, 670, 770) is attached to a surface of the wind turbine blade (10). The surface mounted device (70, 70′, 170, 270, 370, 470, 570, 670, 770) is attached to the surface of the wind turbine blade (10, 610) via at least a first attachment part (77, 77′), which is connected to a part of the surface mounted device (70, 70′, 170, 270, 370, 470, 570, 670, 770). The attachment part (77, 77′) comprises a flexible housing (80, 80′, 680, 780) that forms a cavity (81, 81′, 681, 781) between at least the housing (80, 80′, 680, 780) and the surface of the wind turbine blade (10, 610). The cavity (80, 80′, 680, 780) is filled with an adhesive that provides an adhesive bonding to the surface of the wind turbine blade (10, 610).

Abstract: A serrated panel (70) for a wind turbine blade is disclosed. The panel (70) is configured to be attached to the trailing edge of a blade to form a plurality of serrations (71) at the trailing edge of the blade. The serrated panel comprises a base part (72) for attaching the panel (70) to the trailing edge of the blade. An exterior surface (78) of the base part comprises a corrugated surface in direction between longitudinal ends of the panel such that the exterior surface comprises crests (82) aligned substantially with midpoints of bases (80) of the serrations (71) and valleys (83) aligned substantially between serrations (71).

Abstract: The present invention relates to an embedding element (76) for embedment in a shell structure of a wind turbine rotor blade (10), the element having a wedge-shaped part (85). The embedding element (76) comprises a fibre material and a binding agent, wherein the fibre material is at least partially joined together by means of the binding agent. The inventive element provides improved structural flexibility and elasticity resulting in less wrinkle formation during blade manufacturing. In other aspects, the invention relates to a method of manufacturing the embedding element (76), to a method of manufacturing a wind turbine rotor blade (10) using the embedding element (76), and to a wind turbine blade (10) obtainable by said method.
