Airbus Helicopters

Emmanuelle Roggemans

An architecture for a hybrid power plant for driving a rotorcraft rotor (). The rotorcraft is fitted with an electrical energy distribution network () for distributing electrical energy from a management network () that is interposed between the distribution network () and electrical energy sources (). A management computer () takes account of information about the working of a combustion engine () for driving the rotor (), about the working of the electrical energy sources () fitted to the rotorcraft and including an energy store (), a reversible electric machine (), and an electricity generator () engaged with the combustion engine, and about the electrical energy needs of the electricity distribution network (). Electrical energy is distributed selectively by the management computer () via the management circuit () and to the distribution circuit () depending on priorities of maintaining safe flight of the rotorcraft and providing drive assistance to the engine () as produced by the reversible electric machine ().
