摘要
A wind turbine blade (16) has a suction side surface (20) and a pressure side surface (22). A plurality of dynamic vortex elements (24) are formed on at least one of the suction side (20) or the pressure side surfaces (22). The vortex elements (24) are activatable between a first retracted position that is inwardly recessed relative to a neutral plane of the surface on which they are formed and a second extended position that is outwardly protruding relative to the neutral plane of the surface.
