Abstract

Le rotor (14) pour centrale éolienne est équipé d'une section intermédiaire centrale (22) disposée concentriquement à l'axe de rotation (18) et de plusieurs pales (24), à distance de la section (22), limitées dans leur longueur par une extrémité intérieure (26) et une extrémité extérieure (28) et, dans leur largeur, par deux bords latéraux (30, 32). Chaque pale (24) est reliée à son extrémité intérieure (26), de façon particulièrement rigide avec la section centrale (22). Chaque pale (24) est incurvée et présente un bord latéral incurvé convexe continu, ainsi qu'un bord latéral incurvé concave continu (30, 32). A partir de son extrémité intérieure (26) jusqu'à son extrémité extérieure (28), chaque pale (24) présente une largeur décroissant en continu. Les bords latéraux (30, 32) de chaque pale (24) s'étendent sur l'extrémité intérieure (26) de telle manière qu'ils se transforment tangentiellement en une ligne circulaire imaginaire (20) s'étendant concentriquement à l'axe de rotation (18).
