Abstract

The present disclosure is directed to a rotor blade assembly for a wind turbine. The rotor blade assembly includes a rotor blade having surfaces defining a pressure side, a suction side, a leading edge, and a trailing edge extending between a blade tip and a blade root. Further, the rotor blade assembly includes a flexible extension having a first end and a second end. More specifically, the first end is mounted to a surface of the rotor blade and the second end is free. As such, during operation of the wind turbine, the flexible extension passively adjusts with a changing angle of attack of the rotor blade, thereby reducing variations in blade loading.
