Method for powering autonomous drive motors for an aircraft

摘要

A method for powering an autonomous drive device (4) in an aircraft comprising a certain number of drive motors (5) for the wheels (6) when the jet engines of the aircraft are not activated, the aircraft comprising an auxiliary power unit or APU (2) driving a first generator (1) for supplying power to devices on the aircraft that need to be powered when the jet engines are not activated. The method comprises the use of a second generator (8) dedicated to the power supply of the autonomous drive device, the second generator being disposed in parallel with the first generator so as to be driven by the APU and, when it operates as a motor under the action of power recovered by the autonomous drive device, so as to help the APU drive at least the first generator.

1. A method for powering an autonomous drive device (4) in an aircraft comprising a plurality of drive motors (5) for selectively driving wheels (6) at least when jet engines of the aircraft are not activated, the aircraft comprising an auxiliary power unit (APU) (2) driving a first generator (1) for supplying electric power to electrical devices on the aircraft that need to be powered when the jet engines are not activated, the method comprising:
using a second generator (8) exclusively dedicated to the electric power supply of the autonomous drive device,using a gearbox coupled to the APU and to the first and second generators so that the first and second generators are disposed in parallel, the gearbox being adapted to transmit mechanical power from the APU to the first and second generators so that the first and second generators can be driven in parallel by the APU, and
using the gearbox to transmit mechanical power from the second generator to the first generator when the second generator operates as a motor under the action of power recovered by the autonomous drive device, so as to assist the APU to drive at least the first generator.
