Abstract
A rotor blade for a wind turbine is disclosed. The rotor blade may generally include a shell having a pressure side and a suction side. The shell may define an opening in at least one of the pressure and suction sides. The rotor blade may also include a base and at least two surface features spaced apart along the outer perimeter of the base. The base may generally be movable relative to the opening between a recessed position and an actuated position. Additionally, the base may be rotatable within the shell in order to adjust which of the surface features is received within the opening when the base is moved to the actuated position.
