Abstract

A fluid turbine assembly (1), comprising:

at least a main rotation shaft (2) being configured to rotate around a longitudinal rotation axis (X),a main rotor (3) comprising a central portion and an outer portion, the main rotor (3) being installed on the main rotation shaft (2) in such a way to bring the main rotation shaft (2) in rotation with the main rotor (3),at least an auxiliary rotation shaft (2x),a secondary rotor (10), the secondary rotor (10) being installed on the auxiliary rotation shaft (2x) in such a way to bring the auxiliary rotation shaft (2x) in rotation with the secondary rotor (10),an inlet assembly (4) for a fluid, said inlet assembly (4) being configured to drive a fluid to the main rotor (3) and/or to the secondary rotor (10),wherein at least the main rotor (3) and the secondary rotor (10) have different mechanical characteristics and/or inertia and/or wherein at least the main rotor (3) is configured for delivering a first power and the secondary rotor (10) is configured for delivering a second power,the fluid turbine assembly (1) being configured to provide rotation power and/or torque to the main rotation shaft (2) through the main rotor (3) and/or to the auxiliary rotation shaft (2x) through the secondary rotor (10) or to select the rotation power and/or torque distribution from said main rotation shaft (2) and/or from the auxiliary rotation shaft (2x) 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 (3) or said secondary rotor (10).
