Embodiment Construction

[0033] first reference figure 1 , figure 1 An aircraft is shown provided with a prior art arrangement 10 for supplying electrical power to an aircraft network 12 , in particular for supplying equipment in the cockpit and passenger compartment of the aircraft and an electric taxiing network 14 .

[0034] The networks 12 , 14 are each supplied by generators 16 , 18 driven by an auxiliary power unit 20 , which is then denoted by the acronym APU (Auxiliary Power Unit).

[0035] APU 20 is positioned aft of the aircraft's fuselage and includes drive output shafts (not shown) for the rotors of generators 16 , 18 . The APU 20 is provided with a separate starter (not shown) connected to the battery and means for controlling the starting of the APU.

[0036] The generator 16 has an electric power of 90kVA and supplies an AC voltage Vac2 of 115v to the network 12, which is used in figure 1 is shown schematically by the main distribution unit 22 connected to the generator 16 by electri...

Abstract

An arrangement (210) for supplying electrical power to an aircraft on the ground comprising two generators (216, 218) driven by an auxiliary power unit (220), the first generator being connected / disconnected via a connection / disconnection device (232 ) is connected to the aircraft network (212) and the electrical taxi network (214) so ​​as to supply the aircraft network with an alternating voltage Vac2 when it is connected to this aircraft network, or to supply the taxi network with an alternating voltage Vac1 when it is connected to this taxi network, or Power P, the second generator is connected to the aircraft network or the taxi network through a connection / disconnection device ( 232 ) in order to supply an alternating voltage Vac2 to one of these networks.

Description

technical field [0001] The invention relates to a device for supplying electrical power to an aircraft on the ground, comprising at least two electrical networks: an electrical aircraft network in particular for supplying the cabin and cockpit of the aircraft, and an electrical taxiing network. Background technique [0002] Applications FR 10 / 55457 and FR 10 / 59612 of the Applicant describe, respectively, a device for supplying the electrical network of an aircraft, and an electrical structure for handling the power regenerated by electric actuators during taxiing operations of the aircraft. [0003] Taxiing of an aircraft refers to the circulation or rolling of the aircraft on the ground through the medium of the wheels of the aircraft's landing gear. Taxiing is said to be electric when at least one wheel of an aircraft's landing gear, usually the wheels of the main landing gear, is driven by an electric motor that is part of the taxiing network. [0004] The aircraft netwo...
