Beschreibung
Zusammenfassung:	A wind turbine comprising: at least one pitchable wind turbine blade mounted to a hub, the blade having a root end, a tip end and a longitudinal axis extending between the root end and the tip end, and an aerofoil surface defined by a pressure side and a suction side; and a movable fin mounted at the tip end of the blade, wherein the fin is deployed into a first position in dependence on the pitch position of the blade and when the wind turbine is in a non-operational mode; wherein in the first position the fin extends in a direction substantially aligned with the longitudinal axis of the blade such that the fin acts as an aerodynamic stabilizer to reduce the effects of edgewise vibrations on the blade.
