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.

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 method and mould system for manufacturing I-shaped shear webs for wind turbine blades are described. The mould system comprises a lower web mould part having a concave shape with diverging side parts for manufacturing first sides of I-web foot flanges, and an upper mould part having a concave shape with converging side parts for manufacturing other sides of the I-web foot flanges.
