As the key part of more-electric aircraft(MEA), the more-electric engine(MEE) has been paid high attention by western countries. The research status and developing trends of MEE are reviewed. Then, the ad- vanced technical characters of the key components such as integral starter-generator, magnetic bearing, electric pump and electric actuator are analyzed. The key technologies of high temperature interior integral starter-gen erator,active magnetic bearing and distributed control are also discussed. The MEE will be applied and devel oped in the future for its compact and lightweight structure.
