A turbine device for driving a generator on sailing boats, consisting of a housing (10) with a turbine wheel (11, 20, 21) at one end, a tubular rigid member (17) fixable to the hull of the boat and supporting the housing (10) below the surface of the water, a bevel (16) disposed in the housing (10) and having an input shaft (12) which supports the turbine wheel (11, 20, 21), and an output shaft (19) mounted in the tubular member (17) and connected to a generator. A ring (21) which is coaxial with the centre axis of the housing (10) is mounted around the blades (20) of the turbine wheel (11, 20, 21) and has the general shape of a truncated hollow cone, preferably with a wall which in section has the profile of an airfoil, to maximize the flow through the turbine wheel. |
