Beschreibung
Zusammenfassung:	A wind turbine protected against potentially harmful conditions, such as extreme winds, dust storms or edgewise oscillations, comprises a rotor with a plurality of wind turbine blades and a hub for supporting each of the blades at respective root portions thereof. At least one liftreducing blade cover, such as a net, mesh, or continuous sheet, is accommodable in a collapsed storage configuration at or near the hub, the blade cover being extendible into an extended configuration covering at least a part of a surface of at least one of the blades. A release mechanism is provided for releasing the blade cover from the collapsed storage configuration.
