Prof. Andrew Woodworth

NASA’s Electric Aircraft Propulsion Research: Yesterday, Today and Tomorrow

Speaker Biography:

Dr. Andrew Woodworth is currently a Hybrid Electric Aircraft Materials Technical Lead in the Materials and Structures Division at the NASA Glenn Research Center.  In this programmatic position he advises on a portfolio of work developing megawatt scale powertrain technologies for electric aircraft propulsion. Beyond programmatic duties, Dr Woodworth leads a team developing new material approaches for megawatt scale electric machines. He has also been engaged in hardening SiC based power devices to cosmic radiation.  Dr. Woodworth earned a Ph.D. in Physics from West Virginia University.  He has also worked as a Physical Scientist National Institute for the Occupational Safety and Health, and a Staff Scientist with the West Virginia Nano Initiative.


NASA has been making investments since ~2015 in technologies related to electric aircraft propulsion. These investments span all-electric with our four passenger X-plane and electric vertical lift studies, to regional flight demonstrators and targeted technology maturation programs.  These latter two areas are focused ultimately on reducing fuel burn and overall energy use in transport-class aircraft, with the goal of reducing carbon impact of aviation on our planet.  Key technology contributions include such as electric machines, power electronics, cables/bus bars, fault management systems, controls and systems studies, and enabling materials.  Today we are seeing the fundamental technology investments manifest themselves in flight demonstrations, that are aimed at impacting aircraft entering service 2035-2040 time range.   These efforts have largely been aimed at megawatt scale technologies that can enable hybrid electric or mildly distributed airplane concepts. While these concepts offer benefits to regional and single isle aircraft it is thought that a more fully electrified propulsion system requiring greater than 10 MW of distributed power offers more possible pathways to configure the propulsion-airframe system to gain new efficiencies.  A few examples of this are NASA’s SUSAN distributed electrofan concept and NASA University Leadership Initiatives such as CHEETA and IZEA that champion turbo-electric concepts.  These concepts utilize combination of advanced technologies such as, fuel cells, power dense electronics and power dense electric machines and superconducting technologies.  How much or which of these concepts will be adopted by industry is unclear, however another step function in electrifying aircraft propulsion is now on the horizon.


Mr. Andrew Benn

Standardisation and certification of aircraft electric propulsion systems – Progress and challenges

There is rapid progress in the development of technologies for energy storage and electric propulsion systems as the aerospace industry looks beyond carbon-based fuel dependence and toward a goal of a net-zero carbon economy. The question now is ‘when’ not ‘if’ suitable solutions will be commercially available. An important step in realising this future is the development of all-electric and hybrid electric certification requirements and standards, the framework of which sets the development space for the technology.  This talk will reflect on the scale of the challenge, the engagement of various standards committees and the progress made so far in the development of new standards and certification processes.

Prof. Jin Wang

Title:  Status and Challenges for Wide Bandgap Device based Power Electronics Systems for Aerospace Applications

Speaker Biography:

Jin Wang (IEEE Fellow) received his Ph.D. degree from Michigan State University in 2005. He worked at Ford for two years before joining Ohio State University (OSU) in 2007 as an Assistant Professor. He became a Full Professor at OSU in 2017.

Dr. Wang has over 200 journal and conference papers and 9 patents.

Dr. Wang received the PELS Richard M. Bass Young Engineer Award in 2011, the National Science Foundation’s CAREER Award in 2011, the Nagamori Award in 2020, the First Place Prize Paper Award from IEEE Transactions on Power Electronics in 2021, and the IEEE Power Electronics Emerging Technology Award in 2022. Dr. Wang initiated and served as the inaugural General Chair for the IEEE Workshop on Wide Bandgap Power Devices and Applications (WiPDA) in 2013 and the IEEE Workshop on Power Electronics for Aerospace Applications (PEASA) in 2022.


Aerospace applications are not new but potentially the final frontiers for power electronics research and developments. Wide bandgap (WBG) power devices are regarded as natural candidates for aerospace applications. With great efforts from device manufacturers and system integrators, these devices are either already or close to being implemented in different power converters, actuator drives and circuit breakers for aerospace applications. The main remaining challenges for WBG devices and their circuits for aviation applications include radiation hardness, extreme operation temperature, high altitude, high voltage, high dv/dt, and high di/dt operation induced issues such as lower partial discharge inception voltage and higher EMI noises. The talk will start with an introduction of state-of-the art of power electronics devices and circuits for aerospace applications, then dive into detailed discussions on the above-mentioned challenges. Design examples for both electric propulsion and lunar surface power distribution will be presented.


Dr. Patrick Norman

Designing Resilient Architectures for Hybrid/Full Electric Propulsion Drive Trains in Aircraft

Speaker Biography:

Advanced Electrical Systems, EEE department, University of Strathclyde
Dr Patrick Norman is a Reader in Aerospace Electrical Systems within the Department of Electronic and Electrical Engineering at UoS, where he also received his BEng and PhD degrees. He is the academic lead for Aerospace-Electrical Systems research team, building on 15 years of research experience in the field of more-and hybrid-electrical aircraft systems. During this time, he has been a lead/co-lead investigator on over £4M of aerospace-electrical systems research projects with Innovate UK, EU Clean Sky 2, EPSRC, Raytheon, Rolls-Royce, Airbus, NASA, BAE systems and IHI Corporation, many of which are systems-focussed and interdisciplinary in nature. He is internationally recognised for his work on aircraft power systems modelling, design and protection. His research into new power system architectures and design methodologies has been adopted by a number of leading UK aerospace industries and he holds three patents on protection methods for compact DC aircraft power systems. He has also published over 80 technical papers in leading journals and conferences.


With the move to full or hybrid electric aircraft configurations, new electric-propulsion architectures must be at least as safe as conventional propulsion systems. Achieving this goal, whilst delivering a competitive flight-weight solution requires the parallel consideration of electrical fault protection and management strategies, and redundant/reconfigurable power system architectures. Power electronic converter technologies lie at the heart of both domains, and are therefore key to realising optimal solutions. This talk will explore the opportunities and challenges in this field of research, presenting lessons learnt to date and key focus areas for new R&D.

Prof. Ian Cotton

Title:  Insulation system challenges in electrical transport

Speaker Biography:

IAN COTTON received the B.Eng. degree (Hons.) in electrical engineering from the University of Sheffield and the Ph.D. degree in electrical engineering from The University of Manchester Institute of Technology (UMIST). He is currently Professor of High Voltage Technology with The University of Manchester where his research work is based in the high voltage laboratories. He is involved in work relating to power system equipment used in both terrestrial power and transportation systems. He is also Technical Director of aerospace HV Ltd, a company that specialises in supporting companies working in the aerospace / automotive sectors in designing and qualifying new insulation systems for use in a range of applications.


Aerospace and automotive systems are both seeing an increase in voltage of the electrical power system to support improvements in power density. While the voltages remain low in comparison to the values seen on the electrical transmission system, the operating environment of these systems and the high switching frequencies used pose some specific challenges. This talk will reflect on the key challenges in developing insulation systems suitable for the next generation of electric transport and the work taking place within standards committees to ensure we produce suitable guidance for the manufacturers of the future.
