多电航空发动机研究现况及关键技术

摘要

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.%多电发动机作为多电飞机的核心部件，受到欧美国家的高度重视。介绍了国内外多电发动机的总体研究现状和发展趋势，重点分析了整体式起动／发电机、磁浮轴承、电动燃油泵和电动作动器等多电发动机核心部件的技术特点和性能优势，同时对内置式整体起动／发电机技术、高温主动磁浮轴承技术和分布式控制技术等多电发动机的关键支撑技术进行了讨论。多电发动机结构紧凑、重量轻等优势必将使其得到应用及发展。
