A wind turbine component adapted to be attached to a wind turbine, wherein the component is a cover element adapted to cover at least one part of a wind turbine or an aerodynamic element adapted to be attached to a rotor blade of a wind turbine, wherein the component includes a main body with a continuous and at least partly curved surface, wherein the main body is formed by a layer stack including a plurality of layers, wherein at least two of the layers are of a different material.

Wind turbine component, wind turbine, and method for manufacturing of a wind turbine component

A method for detecting a status of a rotor blade for a wind turbine, the rotor blade including at least an aerodynamic device for influencing the airflow, the aerodynamic device being movable between a first and a second configuration, the method including the steps of: measuring an output signal measured by at least one sensor installed on the wind turbine, moving the aerodynamic device between the first configuration and the second configuration, measuring a change in the induced output signal, post-processing the measured output signal, wherein the post-processing is performed in the frequency domain and includes: deriving a frequency spectrum, calculating an upper spectrum interval of the frequency spectrum above a frequency threshold value, comparing the upper spectrum interval with a reference frequency spectrum deriving a status of the rotor blade based on the step of comparing.
