787 Electric Power Systems and Future Trends in More Electric Airplanes

By: Dr. Kamiar J. Karimi, Senior Technical Fellow, Boeing

Short Biography: Kamiar Karimi received his B.S., Master of Engineering, and Ph.D. degrees in Electrical Engineering from Cornell University in 1981, 1982, and 1986 respectively. From 1986-89 he worked for Landis and Gyr Systems in San Jose, CA where he was in charge of performing research in the area of Energy Management Systems.

Since 1989 he has been with The Boeing Company. He has led system analysis and modeling for the Space Station Power System, and has been involved in design, analysis, and validation of various airplane electric power systems including 747/767/777, and 787. He is one of the architects of the 787 More-Electric systems and is responsible for developing many of the new technologies for 787 electrical power system. Currently he is leading multiple research projects related to aircraft architecture optimization, power conversion technology, and simulation of large complex dynamical systems. He is a Senior Technical Fellow at Boeing.

Abstract: This keynote focuses on More Electric Aircraft (MEA). First, aircraft energy systems are reviewed. All power sources in traditional aircraft are introduced and corresponding power consumers are presented. Then, the MEA concept is detailed and its advantages are discussed. A road to get more electrified is emphasized for Boeing 787 Dreamliner. Advanced technology contributions to fuel efficiency and the role of power electronics in MEA are exposed. Finally, a thorough discussion on future trends in MEA will be held. It goes from load electrification to propulsion system through microgrids and interdisciplinary technologies.
