A device (1) is described for generating energy, composed of at least two ultralight airfoils (3, 5) rotating along their own axis, which functionally reproduce the characteristics of a propeller. The ultralight airfoils (3, 5) which characterise such aerodynamic configuration use pulling means (9, 14, 20) to keep their shape when operating. An important weight reduction of the structure is thereby obtained, which allows different applications in the aeolian generation field.

La présente invention concerne un dispositif (1) permettant de générer de l'énergie, lequel dispositif est composé d'au moins deux surfaces portantes ultra-légères (3, 5) tournant autour de leur propre axe, lesquelles reproduisent fonctionnellement les caractéristiques d'une hélice. Ces surfaces portantes ultra-légères (3, 5) qui se caractérisent par une configuration aérodynamique utilisent des moyens de traction (9, 14, 20) pour conserver leur forme lors de leur fonctionnement. Une réduction importante du poids de la structure peut ainsi être obtenue, ce qui permet différentes applications dans le domaine de la production d'énergie éolienne.
