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.
