摘要：
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 Ωo and K additional damping elements tuned at frequencies Ω1, Ω2, ... Ωk 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 Ωo in a band extended above and below the main resonance frequency of the blade Ωo in a percentage X of Ωo, said frequencies Ω1, Ω2, ... Ωk being comprised within said band. Fig. 3
