    Abstract: A rotor blade assembly of a wind turbine includes a first blade component and a second blade component arranged together at an interface. The interface includes a gap between the blade components. The rotor blade assembly also includes a re-closeable fastening assembly having first and second fastening members. The first fastening member is arranged with a surface of the first blade component or the second blade component. The rotor blade assembly further includes a flexible sealing member arranged so as to cover the gap. The second fastening member is arranged with a surface of the flexible sealing member to align with the first fastening member on the surface of the first blade component or the second blade component. Thus, the flexible sealing member is secured at the interface to each of the first and second blade components via the first and second fastening members.

    Abstract: A rotor blade assembly for mitigating stall-induced vibrations of a wind turbine during standstill includes at least one protrusion secured to the leading-edge of a rotor blade and defining an extended leading edge. The protrusion(s) wraps around a portion of the rotor blade from the suction side to the pressure side of the rotor blade. The protrusion(s) has a root-side face and a tip-side face disposed opposite thereof. The root-side face is arranged at an angle relative to a chordwise reference line. The angle is greater than zero degrees and less than or equal to 45 degrees with respect to the chordwise reference line. The protrusion(s) is configured to affect a chordwise airflow and thereby mitigate a stall-induced vibration.
