Abstract
Dispositif permettant d'obtenir un montage des différents éléments de commandes d'une double variation de calage de l'aéromoteur dans les conditions techniquement admissibles, tel qu'encombrement réduit, facilités accrues de fabrication, résistance plus élevée à l'usine. Un ensemble de deux rampes hélicoïdales, composé d'écrous 5 et 6 et de vis 1 et 2, transforme le mouvement de translation de l'axe support de pale 12 en deux mouvements partiels de rotation correspondant aux deux variations de sens inverse des pales. Ce dispositif commandé par la force centrifuge agit sur deux systèmes de rappel 13-14 dont le second assure aussi une synchronisation des mouvements. L'invention est principalement destinée à la réalisation d'aérogénérateurs de conception robuste et viable dans le temps.
