| 摘要 |
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 end to the upper bulkhead (3) and by the opposed end to the lower bulkhead (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, further result distanced among them to allow the passage through the chamber (20) of a flow, preferably 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) from a side undergoing a first deviation and go out from the opposite side further undergoing a second deviation, generating lift on the blades that it collides with 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. |
