Abstract
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 Ω o and K additional damping elements tuned at frequencies Ω 1, Ω 2, . . . Ω 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 Ω o in a band extended above and below the main resonance frequency of the blade Ω o in a percentage X of Ω o, said frequencies Ω 1, Ω 2, . . . Ω k being comprised within said band.
