摘要:
The aim of the invention is to optimize the entirety of the drive power available in a helicopter by using an auxiliary motor to supply power to the equipment and accessories of the helicopter that are connected to the engines. In an example of an optimized power transfer architecture for implementing the invention, the main engines (1, 1') and the APU group (8), as an auxiliary motor, comprise a gas generator (2; 81) connected, for the main engines (1, 1'), to the gearboxes (6) and accessory boxes (7) of mechanical, electric, and/or hydraulic power sockets, and connected, for the APU group (8), to at least one power conversion member (83, 84, 11). The power conversion member (83, 84, 11) of the APU group (8) is connected to the equipment and accessories via the gearbox (6) and/or via the accessory box (7) of the main engines (1, 1').

The invention relates to a device (210) for supplying an aircraft on the ground with electricity, comprising two electric generators (216, 218) driven by an auxiliary power unit (220), characterized in that the first generator is connected by connection/disconnection means (232) to an aircraft network (212) and to an electrical taxiing network (214), so as to either provide an AC voltage Vac2 to the aircraft network when it is connected to this network, or to provide an AC voltage Vac1 or power P to the taxiing network when it is connected to this network, and in that the second generator is connected by connection/disconnection means (232) to the aircraft network (212) so as to provide this network with an AC voltage Vac2 only when the first generator is supplying the taxiing network.
