Beschreibung
Zusammenfassung:	Wind turbine comprising one or more blades, incorporating in each blade a damping device comprising a first damping element tuned at the main resonance frequency of the blade o and K additional damping elements tuned at frequencies 1, 2, . . . k so that in the event of blade vibrations its amplitude A is reduced in a percentage Y of the amplitude Ao at the main resonance frequency of the blade o in a band extended above and below the main resonance frequency of the blade o in a percentage X of o, said frequencies 1, 2, . . . k being comprised within said band.
