<p>1. A turbine for harnessing the power of moving fluids, particularly wind power, consisting essentially of the combination of a Darrieus-type turbine (1) and a turbine (2) consisting of two voluminous blades (3) rigidly connected to a rotational shaft (4) and symmetrical with respect to said rotational shaft, the turbine (2) forming a starting turbine for the Darrieus-type turbine (1) by being mounted on a common rotational shaft (4') to which the Darrieus-type turbine (1) is rigidly connected in a definitive manner, characterised in that the blades of the starting turbine each have a hyperboloidal section which advantageously extends over an angle at the centre which is slightly less than 180 degrees, and a cross section which is substantially elliptical in plane projection, these blades (3) being assembled together with offsetting at the level of their junction plane, in such a manner as to form two openings in the shape of a crescent, the ends of which narrow to form a channel of semicircular section at each junction point between the sections, and that the starting turbine (2) is rigidly connected to the shaft (4') in an intermittent manner through a connecting device which is controlled or has an automatic action, and in that the starting turbine (2) is mounted inside or outside the Darrieus-type turbine (1).</p> |
