Abstract
A fluid turbine assembly includes a main rotor and a secondary rotor, each operatively coupled to separate rotation shafts and configured for independent operation. The assembly features a fluid inlet system that selectively directs fluid to one or both rotors based on predetermined criteria. The main rotor incorporates hollow arms to distribute fluid centrifugally, while the secondary rotor processes fluid discharged from the main rotor. The assembly includes a control system for independently adjusting power and torque distribution between the rotors to improve efficiency under varying flow conditions. The configuration allows the fluid turbine to manage diverse operating demands, including changes in flow rates and pressure, while optimizing energy output.
Claims21
A fluid turbine assembly, comprising:
- at least a main rotation shaft being configured to rotate around a longitudinal rotation axis;
- 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;
- at least an auxiliary rotation shaft;
- a secondary rotor, the secondary rotor being installed on the auxiliary rotation shaft in such a way to bring the auxiliary rotation shaft in rotation with the secondary rotor;
- an inlet assembly for a fluid, said inlet assembly being configured to drive a fluid to the main rotor and/or to the secondary rotor;
- wherein at least the main rotor and the secondary rotor have different mechanical characteristics and/or inertia and/or wherein at least the main rotor is configured for delivering a first power and the secondary rotor is configured for delivering a second power;
- the fluid turbine assembly being configured to provide rotation power and/or torque to the main rotation shaft through the main rotor and to the auxiliary rotation shaft through the secondary rotor and to allow a selection of an amount of rotation power and/or torque distribution from said main rotation shaft and/or from the auxiliary rotation shaft according to a predetermined and automatically selectable criterion of selection of rotation power and/or torque transmission from at least one between said main rotor or said secondary rotor.
