Abstract

L'invention concerne un régulateur de vitesse pour éoliennes à arbre vertical à utiliser dans une conception d'éolienne à arbre vertical. Le régulateur de vitesse se constitue de plusieurs panneaux de canalisation du vent pivotants qui sont interconnectés et disposés suivant une géométrie autour du rotor de l'éolienne à arbre vertical. Chaque panneau pivote autour d'un axe vertical correspondant de façon à se déplacer selon différents angles par rapport à la périphérie du rotor et par rapport au vent. Les panneaux visent trois objectifs; rendre le rotor inerte lorsqu'il est fermé, réguler la vitesse du rotor, et canaliser le vent en direction du rotor afin d'augmenter la puissance.
