<p>The invention relates to a rotor converting the naturally flowing fluid kinetic energy into mechanical energy. According to the invention the rotor comprises a central shaft (1) and it is equipped with two or more blades (4) symmetrically located around the central shaft (1), each blade (4) consisting of two semiblades (4a and 4b) articulated to one of some intermediary shafts (5), all the intermediary shafts (5) being stiffened at the ends with the central shaft (1), at the level of two polygonal frames (6, 7), with the number of sides correlated with the number of blades. The two semiblades (4a and 4b) can be closed and opened within the range 0 ... 180A and are hindered to rotate freely about one of the intermediary shafts (5), so that at the blade (4) facing the fluid flow direction the two semiblades (4a and 4b) are opened under the pressure thereof, causing the central shaft (1) to rotate and transfering some of the fluid energy thereto, and at the blade (4) with the back to the fluid flow direction the two semiblades (4a and 4b) are closed under the pressure thereof, lowering to minimum the antagonistic force and the energetic losses, respectively, on the blade (4) return path.</p> |
