摘要： 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).

摘要： A wind turbine blade is described having noise reduction features. The blade has a plurality of projecting serrations provided at the blade trailing edge to reduce the scattering noise produced during operation of the blade, wherein the serrations have a plurality of through-going apertures defined in the serration body. The apertures act to provide a pressure equalization effect at the serrations between the suction and pressure sides. This pressure equalization provides for improved noise reduction performance, as well as a reduction in mechanical stresses and strains which may be experienced by the serrations, increasing serration lifetime.

摘要： A method for manufacturing a part for a wind turbine blade, and in particular a part of a shear web for a wind turbine blade, is described. The method comprises pultruding the part, wherein an in-line shaping of the part is performed, to provide a part having a cross-sectional profile which varies in the longitudinal length of the part. Providing a shear web having a portion which varies in cross-sectional profile results in production of a wind turbine blade part which can be accurately controlled to have precise geometrical profile corresponding to a desired blade profile, with minimal waste of materials.

摘要： A bulkhead assembly for a wind turbine blade is described, where the bulkhead is substantially formed from a flexible sheet material. In one aspect, the flexible sheet material can be attached to the larger assembly using a releasable connection, e.g. a zipped connection, to allow for relatively easy installation and removal, e.g. for repair or other service operations. At least a portion of the sheet material may be transparent, to allow for easy inspection of the interior of the wind turbine blade. In one aspect, the bulkhead assembly is arranged to couple to, or is formed integrally with, the root flange of a wind turbine blade. The use of such a flexible material to form the blade root end bulkhead allows for ease of handling and manufacturability over prior art systems.

摘要： A system and method for the manufacture of a wind turbine blade component is described, preferably a shear web component for a wind turbine. The shear web is manufactured by using a forming tool to define a flange-shaped cavity at an end of a web member. A resin is injected into the cavity and cured to form a flange cast onto the web member. The forming tool is subsequently removed from the web member to provide a component having a load-bearing flange formed from a cured resin.
