Abstract

L'invention concerne une turbine éolienne comprenant un premier ensemble d'aubes de turbine éolienne montées à des fins de rotation autour d'un axe de rotation, et un second ensemble d'aubes de turbine éolienne montées à des fins de rotation autour de l'axe de rotation par rapport au premier ensemble d'aubes. Chaque aube du premier ensemble d'aubes de turbine éolienne comprend une surface d'aube formée par au moins deux parties d'aube. Par ailleurs, chaque aube du second ensemble d'aubes comprend une surface d'aube qui est formée par au moins une partie d'aube, ayant une configuration de surface d'aube différente par rapport à la surface des aubes du premier ensemble d'aubes.
