Abstract:
1. An architecture for supplying mechanical power to a rotorcraft rotor from hybrid energy, the architecture associating at least one combustion engine fitted with an operating mode regulator and at least one reversible electric machine fitted with an operating mode regulator, said architecture comprising: a drivetrain for driving the rotor from at least one power plant comprising the engine engaged with the reversible electric machine, the drivetrain comprising a main gearbox engaged with the rotor and engaged with the engine to be driven thereby; at least one electrical energy store supplied with electrical energy from the reversible electric machine and from at least one electricity generator fitted with an operating mode regulator, the electricity generator being driven in rotation from the drivetrain; an on-board electricity network of the rotorcraft collecting and distributing electrical energy from electrical energy sources comprising at least the reversible electric machine, at least the electricity generator, and at least the electrical energy store, the on-board network comprising an electricity distribution network dedicated to supplying equipment of the rotorcraft with electrical energy; and a man-machine interface associated with a command calculator via which man-machine interface a pilot can act on a plurality of members of the rotorcraft to modify their working, the members of the rotorcraft comprising at least one power plant and the equipment to be supplied with electrical energy; wherein the on-board network comprises an electrical distribution architecture including the electrical energy sources, a management network, and a management computer, the management network being distinct from the electricity distribution network by being interposed between the electrical energy sources and the electricity distribution network, operating mode of the management network being dependent on the management computer in communication with communication interfaces for issuing management information, on the basis of management information the management computer operates the management network by selectively distributing the electrical energy delivered by the electrical energy sources via the management network and to the distribution network from the management network.
