Title: ROTOR BLADE WITH NOISE REDUCTION MEANS
Abstract:
The invention relates to a rotor blade of a wind turbine with noise reduction means. The rotor blade comprises a leading edge section, a trailing edge section, a pressure side and a suction side. The noise reduction means is attached to the trailing edge section. The noise reduction means comprises a passage for influencing the airflow flowing from the leading edge section to the trailing edge section, such that noise, which is generated by the interaction of the airflow and the rotor blade, is reduced.
