Abstract

The present invention concerns an innovative rotor (1') for an aero-generator comprising an upper bulkhead (3), a lower bulkhead (2) and a rotational axis (7) around which the rotor is rotatable. A plurality of blades (1) are connected by one of their ends to the upper lower bulkheads (2) in such a way as to form an internal chamber (20), rotatable around the said rotational axis (7). The blades, of a predetermined airfoil, allow the passage through the chamber (20) of an air flow, and are arranged according to a certain blade pitch angle in such a way that, in use, when the flow collides with the chamber (20), it can go into the chamber (20) and go out from the opposite side, generating lift on the blades and therefore causing a rotation of the rotor (1'). In accordance with the invention, the blades have an airfoil with high curvature and are further arranged according to an angle of incidence comprised within a variable range between 30° and 60°, preferably between 37° and 52°, in such a way as to increase the lift forces.
