Abstract: A wind turbine blade is described, as well as a trailing edge plate for a wind turbine blade. A flexible flow modulation device, e.g. an acoustic flap or a plurality of serrations, is arranged at the trailing edge of a wind turbine blade, wherein the flexible device is coupled to at least one aerodynamic device, preferably vortex generators. As the flexible device is bent by action of flow over the wind turbine blade, the at least one aerodynamic device is deployed to provide for attached flow over the bent flexible device.

Abstract: A method of manufacturing an aerodynamic shell part for a wind turbine blade is described. The aerodynamic she part comprises a recess for arrangement and connection of a spar cap within said recess. The method comprising the steps of: a) providing a first mold part having a first forming surface that defines a part of an exterior of the aerodynamic shell part, b) laying up fiber-reinforcement material and optionally also sandwich core material in the first mold on the first forming surface, c) arranging one or more inserts having an exterior shape corresponding to at least sides of the recess of the aerodynamic shell part, d) supplying resin to said fiber-reinforcement material and optional sandwich core material, e) curing or preconsolidating the resin, and f) removing the one or more inserts.

Abstract: A repair solution for a wind turbine blade is described. The repair solution includes the application of a layer of viscous coating material to the section of the blade to be repaired, which is cured to form a repaired surface. The layer of viscous coating material may be temporarily covered during the curing process using a film of Low Surface Energy material, to prevent defects in the repaired surface from dust, insects, etc. Additionally or alternatively, a temporary shield may be erected adjacent the curing layer of coating material, to allow for the control of the temperature and/or humidity levels of the region adjacent the curing material, to provide for more effective control of the curing process and to allow for repairs to be carried out for a wider process window.
