Title:
INTEGRATED ELECTRIC PROPULSION SYSTEM FOR ELECTRIC AIRCRAFTS
Document Type and Number:
WIPO Patent Application WO/2024/060567
Kind Code:
A1
Abstract:
An integrated electric propulsion system for electric aircrafts. A distributed electric propulsion system and a fly-by-wire flight control actuation system which are integrated on aircraft wings can be unified, thereby providing for the electric aircrafts reliable, efficient and stable flight power, and meanwhile reducing the weight and energy loss of the system. The integrated electric propulsion system for electric aircrafts is independent from an airborne electric energy system on which a plurality of electrified loads are mounted, and the integrated electric propulsion system for electric aircrafts integrates a distributed electric propulsion system and a fly-by-wire flight control actuation system which are integrated on wings of an electric aircraft, so as to connect same with a unified power supply system. In case of normal power supply, power is supplied via a first power supply path to the distributed electric propulsion system and the fly-by-wire flight control actuation system. Under a failure condition that normal power supply is partially failed or an emergency condition that the normal power supply is all failed, by means of an energy management part, the path for supplying power to the distributed electric propulsion system and the fly-by-wire flight control actuation system is switched to a power supply path different from the first power supply path.
