Overview of MEA key technology and system integration

摘要

More electric aircraft (MEA) becomes a trend for next generation aircraft to respond to the global wide energy shortage. The technological advancement in power electronics makes MEA possible. Airbus and Boeing have advanced their research and application 30 years or earlier than China does. As a major civil aircraft manufacturer in China, COMAC can play an important role in applying and promoting new technologies for next generation aircraft. Based on authors' practice in recent years MEA development project, in this study, the challenge for MEA design is identified and the key technologies for MEA are elaborated from the aircraft, system and component level, and an attempt is made to address the challenge encountered. The method for MEA system integration is given in lieu of ARP 4754A. Finally, an innovative collaboration between original equipment manufacturer (OEM) and suppliers is suggested to achieve wina??win situation in developing next generation aircraft.
