  • Publication number: 20250162720
    Abstract: An aircraft power supply network and associated aircraft, the power supply network includes a first engine and a second engine, a first and a second set of loads, an auxiliary electrical source and a first electrical machine connected to the first engine. The power supply network also includes a first converter connected to the first electrical machine, a first interconnection bus connected to the first converter by a first primary switch and to the first set of loads and a second electrical machine connected to the second motor. The power supply network further includes a second converter, a second interconnection bus, connected to the second converter by a second primary switch and to the second set of loads, a sharing bus connected to the first interconnection bus by a first inter-bus switch, connected to the second interconnection bus by a second inter-bus switch and connected to the auxiliary electrical source.

  • Patent number: 11827374
    Abstract: In the field of multi-rotor rotary-wing aircraft a propulsion system for such an aircraft includes a reconfigurable electric network for supplying the electric motors driving the rotors. The system includes: a supply source, a supply bus connected to the supply source, at least four drive units each including an electric motor and its control circuit, and an electrical ring network including: an electrical line which is interrupted at each drive unit and whose ends are connected to the supply bus, and, for each drive unit, a first switch and a second switch that are connected between the control circuit and the electrical line, on either side of the interruption.

  • Publication number: 20220204173
    Abstract: An electrical energy supply network of an aircraft equipped with a plurality of electrical loads to be supplied includes at least two generators of a turbogenerator of the aircraft, each suitable for providing an electrical energy source, and at least one stator associated with a rectifier. The stators of the generators are mounted in parallel on at least two distribution buses designed to supply the plurality of electrical loads. The supply network also includes contactors suitable for electrically connecting or disconnecting the distribution buses from each other.
