Abstract

Une conception nouvelle et avantageuse d'une éolienne conçue pour une rotation lente du rotor est obtenue par la réalisation d'une, deux ou plusieurs rangées parallèles de générateurs de vortex à sous-couches limites, ce qui permet d'obtenir une pale qui résiste au décrochage et assure un coefficient de portance maximal CL,maχ des pales ainsi qu'un profil de pales plus effilées, et un coefficient de plénitude de rayon spécifique plus bas du rotor. Le coefficient de portance très élevé CL permet une conception nouvelle et avantageuse d'un rotor qui fonctionne avec une vitesse peu élevée des pointes, qui réduit la génération du bruit aérodynamique. La ou les rangées parallèles de générateurs de vortex à sous-couches limites sont fournies, dans un mode de réalisation préféré de l'invention, dans une combinaison avec des Volets de Gurney générant un coefficient de portance CLtrès élevé avec un décrochage relativement bénin à un angle d'attaque très élevé.
