Chris Severns is an Associate Technical Fellow at the Boeing Company with a specialization in Aircraft Electrical Power Systems. Chris began his 35+ year career in electrical systems in the United States Navy maintaining and operating nuclear powered submarine systems. In the context of electrical systems and the “electrification” of vehicle systems, he has worked on a wide range of applications and projects which have advanced “more electric” vehicle systems. Specific examples include: the first electrically powered remotely operated vehicles for the localization of sea mines in a combat zone; the International Space Station electrical system which integrated multiple conversion levels with “new” power quality and stability criterion; Hall Effect satellite thruster design; a diesel engine-generator installed in the cargo bay of a 737 jet aircraft for in-flight power (lead designer); and a Lithium-Ion battery based “Electric” Auxiliary Power Unit for the Space Shuttle.
His 25 year career at Boeing has spanned several Boeing products and programs in the Commercial, Defense, and Research units of the company. He is currently assigned to Boeing Commercial Airplane’s Product Development, and is the Principal Investigator on a Robust and Reliable Power Systems which is targeted at enhancing design and test methods.
From 2000 to 2002, Chris worked for the German Airship company CargoLifter, as the lead electrical engineer. He also was instrumental in a conceptual design for a fuel cell powered airship which would maintain “neutral” buoyancy.
Chris received his Bachelors of Science in Physics from Guilford College, and a Master’s of Science in Electrical Engineering (Power Systems) from the University of Washington. He is a retired Naval Reserve Officer and a graduate of the United States Naval Nuclear Propulsion program. Chris is also the Chairman of the Society of Aerospace Engineer’s section AE-7B for aerospace power distribution, management, and energy storage.
The title of his keynote is “Prime Movers in Air Vehicle Electrification: Trajectories of Technology”. For over 135 years, “Electrification” of air vehicles has been underway. The growth in electrical power utilization and its application to various vehicle functions, has grown steadily over the past several decades. With the advent of electric propulsion and hybrid-electric systems, it is now at a bifurcation point. Due to environmental considerations and pressures, energy economics and advances in technology, industry has accelerated down the path of full electrification- although the existing hydrocarbon based systems energy and power densities are still unmatched. This presentation is intended to provide a brief overview of where the industry has come from, where we are at with current technology, and help identify the direction technology is being developed. It will also briefly attempt to identify basic vehicle considerations, constraints, and areas needing development.

The title of his keynote is “Electric and Hybrid Propulsion of Aircraft – Power conversion opportunities and challenges”. Gas engines are used in today’s commercial aircraft. It is envisioned that next step is to hybridize or use full electric propulsion systems to minimize the emissions, increase the reliability, and reduce the cost of flying. This talk will have two sections. In first section, Dr. Sarlioglu will present the most recent developments in electric and hybrid propulsion of aircraft as well as more electric aircraft initiatives. In the second section, the needs, requirements, and power densities for electric motor and power electronics will be addressed. New material technologies and design approaches along with challenges and opportunities will be presented to achieve aerospace-grade high power density and high efficiency motors and power electronics.

The title of his keynote is “Dynamic Wireless Charging: Magnetics, Electronics, and Integration Requirements”. Electric Vehicle (EV) have the potential to achieve eco-friendly transportation, however the major limitation in achieving this vision is the battery technology. It suffers from drawbacks such as high cost, rare material, low energy density and large weight. The problems related to battery technology can be addressed by dynamically charging the electric vehicle while on the move. In-motion charging can reduce the battery storage requirement which could significantly extend the driving range of an electric vehicle. This talk highlights recent advances in stationary and dynamic wireless charging of electric vehicles. A comprehensive review of charging pad, power electronics configurations, compensation networks, controls, and standards is presented. Examples from modeling and experimental verifications will be included to validate the proposed solutions.

Hydrogen Proton Exchange Membrane (PEM) fuel cell is considered today as a promising technology for low-carbon transport applications. The successful deployment of fuel cell technology in automotive sector is a key element to reach out the European Union’s CO2 emission goal by 2050. After years of developments by research institutions and enterprises, the automotive fuel cell technology has gradually introduced to the market since 2015. In this keynote, we will explore together the key technologies of modern commercial fuel cell electric vehicles, such as Toyota Mirai, Honda Clarity Fuel Cell, etc. The place of fuel cell technology in our future low-carbon transports and the main challenges will also be discussed.
Oliver Simmonds is a Principal Engineer at BMT, within the Defence & Security Partnership in Bath, UK. A Chartered Engineer, he has a background in both Mechanical and Electrical Engineering and has lead several major projects ranging from the delivery of a hybrid power and propulsion system for a Naval auxiliary vessel through to a wide range of technology studies and concept development work with a focus on The Electric Ship.
The title of his keynote is “Completing the Electric Ship”. In 1995 the first in a series of papers was published discussing the many benefits potentially offered by The Electric Ship and how such a ship might be realised as a future naval platform. Now, over 20 years later, this paper looks at how far the electric ship has come and going forward what further development is required. It identifies that whilst there has been significant advancements in Integrated Full Electric Propulsion, with examples such as the Type 45 Destroyer, the original aim has not yet been achieved, partly due to the expected high energy loads for the combat systems only recently being fully developed. The presentation concludes with re-stating the aim of The Electric Ship and identifying what development is needed to ensure that the technology is ready for the next future platform.
