Abstract: A wind turbine blade having a surface mounted device attached thereto via at least a first attachment part, which is connected to a part of the device. The first attachment part comprises an outer attachment part providing a first bonding connection between the device and the surface of the blade, wherein the first bonding connection is an elastic bond, and an inner attachment part providing a second bonding connection between the device and the surface of the blade, wherein the second bonding connection has a structural bond. The structural bond prevents the surface mounted device from creeping and the elastic bond region relieves stresses on the bond line, such as peel stresses, whereby the surface mounted device is less likely to be ripped off the surface of the blade due to forces affecting the device or the blade.

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 wind turbine blade bushing system for arrangement in a root end of a wind turbine blade is described. The wind turbine blade bushing system comprises a threaded element for retaining a mounting bolt for a wind turbine blade, the threaded element being formed from a first material; and an anchor element for arrangement at the root end of the wind turbine, wherein the anchor element acts to at least partly retain the threaded element in the wind turbine blade, the anchor element being formed from a second material. The first material has a higher strength and higher fracture toughness than the second material.

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: A wind turbine blade having a transition between two reinforcement fiber types is described. A gradual transition is provided by a combined double-tapered thickness section with a first type of reinforcement fibers sandwiched between a second type of reinforcement fibers or vice versa. The double-tapering is provided during layup and the reinforcement material is impregnated with a polymer resin and then cured or hardened so that the two types of reinforcement fibers are embedded in a common polymer matrix.
