Fluid turbine assembly and method of actuation of a fluid turbine

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).
