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 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 trainée, qui présentent des complémentarités à plusieurs niveaux.The invention dismays a device for transforming the kinetic energy conveyed by an aerodynamic or hydrodynamic flow, into exploitable kinetic energy, this device combines the two classic configurations soapius and darrieus, the said device is transformable, with variable geometry, using a blading retractable, and combined with a mechanical system that ensures this transformation, passing from one configuration to another according to the air flow speed and external conditions, which makes it exploit the aerodynamic forces of lift type and drag, which present complementarities at several levels.
