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 characterize such aerodynamic configuration use pulling means ( 9, 14, 20 ) to keep their shape when operating. An important weight reduction of the structure is thus obtained, which allows different applications in the aeolian generation field.
