MULTIPLE VENTURI WIND TURBINE

摘要

The invention relates to a device (1) for capturing the power of a fluid current (F), said device including a rotor (2) provided with at least one blade (3) that sweeps a sweeping path (6) in space when the rotor is driven. Said device (1) is characterized in that it comprises a propulsion channel blade level (12) that consecutively includes, along said sweeping path, at least one first Venturi acceleration level (16), provided with a first pair of deflectors (14, 15) that are placed opposite each other on each side of the sweeping path, and at least one second Venturi acceleration level (116), provided with a second pair of deflectors (114, 115) that are placed opposite each other on each side of the sweeping path. The invention relates to the field of wind turbines.
