Device for electrically powering an aircraft on the ground

摘要

An electrical power supply device for an aircraft on the ground, the device including two electricity generators driven by an auxiliary power unit, wherein the first generator is connected by a selective connection/disconnection mechanism to an aircraft network and to an electrical taxiing network, and is configured to deliver either a first AC voltage to the aircraft network when it is connected to that network, or an AC voltage or a power to the taxiing network when it is connected to that network, and wherein the second generator is connected by the connection/disconnection mechanism to the aircraft network to deliver the first AC voltage to that network solely when the first generator is powering the taxiing network.

1. An electrical power supply device of an aircraft disposed on a ground, the device comprising:
first and second electricity generators driven by an auxiliary power unit, the first electric generator powers an electrical taxiing network including electric motors for driving wheels of the aircraft, the second electricity generator powers an aircraft electricity network, wherein the first electricity generator is connected by selective connection and disconnection means to the aircraft electricity network and the electrical taxiing network, wherein the first electricity generator delivers a first AC voltage to the aircraft electricity network when connected to the aircraft electricity network, and delivers one of a higher AC voltage and an electrical power to the electrical taxiing network when the first electricity generator is connected to the electrical taxiing network, and wherein the second electricity generator is connected by the connection and disconnection means to the aircraft electric network to deliver the first AC voltage to the aircraft electricity network only when the first electric generator is powering the electrical taxiing network, and is disconnected by the connection and disconnection means to the aircraft electricity network when the first electricity generator is powering the aircraft electricity network.
