Synopsis

This short course is designed for engineers in the aerospace industry who would like to learn more about the electrical technologies that enable More-Electric and Hybrid-Electric Aircraft. Studies show that significant reduction in the mission fuel burn can be obtained with electric/hybrid-electric propulsion on commercial transport aircraft without compromising payload, range, or cruise speed. The course will introduce the fundamental concepts and trade-offs involved in the design of the electrical systems for such airplanes. The material is presented at an introductory level to be accessible for people without a deep electrical engineering background, although a basic working knowledge of electromechanics and physics is assumed. Topics covered include the basic design of electrical machines and drives, power distribution and protection systems, enabling power electronics (design, circuits, devices), modeling and simulation of large integrated systems, and general MEA and Electric/Hybrid-Electric propulsion design considerations.

Learning Objectives

Upon completion of the course, participants will:
  • Understand the fundamentals of electromechanical energy conversion
  • Understand fundamentals of enabling power electronics
  • Understand the key drivers of electrical machine and drive designs
  • Have a basic understanding of electrical power distribution architecture

Course Instructor

Dr. Tim O'Connell received a B.A., summa cum laude, in Physics from Carleton College in Northfield, MN, in 2003 and M.S. and Ph.D. degrees in Electrical Engineering from the University of Illinois at Urbana-Champaign, in 2005 and 2008, respectively. He is currently a Senior Lead Engineer with PC Krause & Associates (PCKA), West Lafayette, IN, where he has served as the lead engineer in charge of adaptive power and thermal management system (APTMS) model integration for the Air Force Integrated Vehicle Energy Technology (INVENT) Spiral 1 next generation fighter aircraft program, and he is currently the modeling and simulation team lead for the INVENT Spiral 2 effort. Additionally at PCKA, Tim has created a high-fidelity transient model capable of predicting the off-axis dynamics of a cantilevered switched-reluctance generator, modeled and simulated bidirectional power converter architectures for use in aircraft electrical accumulator units (EAUs), has lead an effort to design a modular power system architecture for unmanned underwater vehicles (UUVs), has investigated the electromechanics of an unmanned aerial vehicle (UAV) electric generator, and has designed a detailed automated finite-element analysis code for analyzing aircraft generators. He has over a decade of experience using Matlab/Simulink and is a veteran user of Comsol Multiphysics finite element software. Tim won the 2010 SAE Charles M. Manly Memorial Medal for the "best paper relating to the theory or practice in the design or construction of, or research on, aerospace engines, their parts, components, or accessories and which has been presented at an SAE meeting" for his paper "A Hybrid Economy Bleed, Electric Drive Adaptive Power and Thermal Management System for More Electric Aircraft"."

Bob Bayles is a Senior Fellow engineer at UTC Aerospace Systems in Rockford, IL. Bob is currently involved in the exploration of more electric systems on airplanes including the opportunities to integrate and optimize various airplane subsystems. Bob holds a Bachelor's and Master's degree in electrical engineering and a Master's degree in business administration.

Kiruba Haran obtained a Ph.D. in Electric Power Engineering from Rensselaer Polytechnic Institute, Troy, NY, in 2000. He spent 13 years as a senior engineer and manager of the research group developing advanced electrical machine technology for all of GE's industrial businesses. He moved to the University of Illinois in 2014 as an Associate Professor and Associate Director of the Grainger Center for Electric Machinery and Electromechanics. His research focus in recent years has been on high specific power electrical machines and drives, with both superconducting and non-cryogenic approaches. Kiruba serves on the Steering Committee of the IEEE Transportation Electrification Community, and the Editorial Board of the IEEE Transactions on Energy Conversion. He is also the current Chair of the Electric Machinery Committee and a Distinguished Lecturer of the IEEE Power and Energy Society. Kiruba is a registered Professional Engineer in New York and is a Fellow of IEEE.
