Abstract: A system and method for reducing the operational noise of a blunt trailing edge of a wind turbine blade is described. The system involves increasing the trailing edge solid angle at the blade trailing edge by providing a wedge element or projection adjacent the trailing edge of the blade, the wedge element acting to provide improved mixing of the suction side and pressure side flows at the blunt trailing edge, thereby reducing the strength of vortex shedding at the trailing edge and the associated operational noise.

Abstract: 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.

Abstract: 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.

Abstract: 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.
