Abstract

L'invention consterne un dispositif de transformation de l'énergie cinétique véhiculé par un écoulement aérodynamique ou hydrodynamique, en énergie cinétique exploitable, ce dispositif combine les deux configurations classiques Savonius et Darrieus, le dit dispositif est transformable, à géométrie variable, utilisant un aubage pliable, et combiné à un système mécanique qui assure cette transformation, en passant d'une configuration à une autre selon la vitesse d'écoulement de l'air et les conditions externes, ce qui fait qu'elle exploite les efforts aérodynamiques de type portance et traînée, qui présentent des complémentarités à plusieurs niveaux.
