Beschreibung
Zusammenfassung:	The invention relates to a device for converting the kinetic energy conveyed by an aerodynamic or hydrodynamic flow into usable kinetic energy, said device combining the two conventional Savonius and Darrieus configurations, said device being convertible, having a variable geometry, using a retractable blade system, and being combined with a mechanical system which enables said conversion, switching from one configuration to the other according to the wind speed and the external conditions, enabling the device to use aerodynamic forces such as lift and drag, which complement one another on a number of levels. 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 escamotable, 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.
