Description

technical field [0001] The invention relates to a power supply system architecture of a single-channel multi-electric aircraft. Background technique [0002] In the past few decades, the aviation industry has made great progress in the field of More Electric. Many systems that were previously driven by hydraulic, mechanical and air sources have gradually been driven by electric energy to reduce the emission of aircraft pollutants. , Improve fuel economy. The Boeing 787 is a poster child for this trend. [0003] Boeing 787 cancels the traditional air source system. This design optimizes the use of aircraft energy and improves the efficiency of the engine. Due to the cancellation of various parts of the air source system (valve, pipe, etc.), the weight of the aircraft is reduced, the reliability of the system is significantly improved, and the maintenance cost of the aircraft can also be effectively reduced. [0004] The power supply system of the Boeing 787 aircraft is qui...
