Abstract: A wind turbine blade (10) is described having a serrated trailing edge (20). Splitter plates (106) are provided on the blade, to reduce operational noise. Each splitter plate (106) is arranged to extend at least partly into a space in between adjacent serrations. The splitter plates can be formed integrally with the serrations, or attached to existing serrations as a retrofit solution. The serrations with the splitter plates can be provided as a trailing edge panel (108) for attachment to the trailing edge of an existing wind turbine blade.

Abstract: A wind turbine blade is described having a serrated trailing edge. Flow straightening vanes are provided on the serrations, to prevent a lateral or side flow over the edges of the serrations, which are preferably provided at incidence to the flow over the wind turbine blade. The vanes can be formed integrally with the serrations, or attached to existing serrations as a retrofit solution. The serrations with the vanes can be provided as a trailing edge panel for attachment to the trailing edge of an existing wind turbine blade.

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.
