Abstract

L'invention porte sur des pales à élongation verticale pour éolienne, dans laquelle les pales mobiles, équilibrées par la force centrifuge lors de la rotation des pales à élongation verticale, sont montées sur les extrémités postérieures de celles-ci dans leur direction de rotation. Lors d'un vent à vitesse élevée, l'effet de freinage des pales mobiles maintient la vitesse de rotation de l'éolienne à un niveau spécifique. Les pales à élongation verticale d'une éolienne à axe vertical sont montées à l'aide de bras de support (5) de manière à s'étendre verticalement autour d'un arbre principal vertical (2) de l'éolienne à axe vertical. Les pales mobiles (7) sont montées aux extrémités postérieures des sections de corps principales (6A) dans la direction de rotation de celles-ci, de telle sorte que les pales mobiles peuvent être équilibrées par la force centrifuge générée par la rotation de l'éolienne.
