Title (EN) WIND TURBINE BLADE
(FR) AUBE D'EOLIENNE
Abstract:
(EN) An aerodynamic profile and a wind turbine comprising a wind turbine blade with reduced sensitivity towards surface irregularities are provided. The invention is mainly directed towards pitch-regulated wind turbines, which are operated at variable rotor speed and have blades longer than about 30 meters.
(FR) L'invention concerne un profil aérodynamique et une éolienne comprenant une aube d'éolienne présentant une sensibilité réduite vis-à-vis des irrégularités de surface. L'invention se rapporte essentiellement à des éoliennes à réglage de pas mises en oeuvre à une vitesse de rotor variable et comportant des aubes dont la longueur est supérieure à environ 30 mètres.
