Fluid turbine assembly and method of actuation of a fluid turbine

A method of actuating a fluid turbine assembly, the method comprising:

• providing at least a main rotation shaft being configured to rotate around a longitudinal rotation axis;
• providing a main rotor comprising a central portion and an outer portion, the main rotor being installed on the main rotation shaft in such a way to bring the main rotation shaft in rotation with the main rotor;
• providing an inlet assembly for a fluid, said inlet assembly being configured to drive the fluid to the main rotor, wherein said inlet assembly comprises a Venturi conduit comprising a first inlet configured to be connected to, and to be fed in use with, a pressurized primary fluid source, and a second inlet configured to be submerged into, and to drag fluid from, a secondary fluid source to the rotor under the dragging effect caused by the fluid flowing in said first inlet;
• wherein the main rotor comprises a plurality of hollow arms at least partially arranged along a radial direction, said plurality of hollow arms realizing a plurality of fluid distribution conduits configured to allow, in use, the distribution of fluid from the central portion of the main rotor to the outer portion of the main rotor;
• and
• wherein each arm of the plurality of hollow arms comprises a central portion, and a distal portion positioned at the outer portion of the main rotor, each distal portion being arranged in a direction inclined with respect to the radial direction and to said longitudinal rotation axis, and being configured to direct, in use, the fluid to a predetermined direction to cause the rotation of the main rotor by means of a reaction force;
• and
• providing fluid from the inlet assembly to the main rotor, thereby driving rotation of the main rotor;
• wherein the step of providing fluid to the main rotor comprises:
• feeding the fluid to the first inlet of the inlet assembly by way of the pressurized primary fluid source which, in turn, feeds the fluid to the Venturi conduit of the inlet assembly;
• and
• feeding the fluid to the second inlet of the inlet assembly with the fluid dragged from the secondary fluid source in such a way that the fluid dragged from the secondary fluid source can be driven to the rotor under the dragging effect caused by the fluid flowing in said first inlet.
