There’s a transformation occurring in aerospace: the change to more electric aircraft and electric propulsion. One of the biggest upheavals since the jet engine, electrification will have a major impact, from the environment to radical new flight operations, simplifying onboard systems with consequential maintenance implications, to altering the urban landscape to accomodate new vehicles. But it can only deliver its true potential if the public are positively engaged.

This year’s Ewing will examine this transition, covering materials, motors, aircraft, public engagement and systems, with the aim of creating, developing and cementing relationships within the magnetics community throughout Europe and the UK.

It will be a full day event, with a full technical seminar of talks, followed by a drinks reception and informal dinner in the evening.

The Ewing Lecture will be given by Prof Chris Gerada of the University of Nottingham, Associate Pro-Vice-Chancellor for Industrial Strategy, Royal Academy of Engineering Chair of Electrical Machines, member of the university’s Power Electronics, Machines and Control group.

More information as we develop the event.


  • Mr Jeremy Tompkins, Vacuumschmelze GmbH & Co KG


We are pleased to announce Prof Dr Elena Lomonova of the Electromechanics & Power Electronics Group at Eindhoven University of Technology has accepted our Lifetime Contribution to Magnetics award, and will be present in person at the Ewing to accept the award and deliver a presentation.

The committee felt Prof Lomonova had set an excellent example through her multi-disciplinary approach to fundamental and applied research in mechatronics and electromechanical motion systems, power electronic system architectures, and power converters, leading to novel and effective solutions and an impressive output of projects, papers and patents. In addition, she has led her university research unit to great effect in bridging the academic / industrial gap.


The whole event will be held at the world famous Imperial War Museum Duxford aircraft museum near Cambridge, with the reception and dinner in the museum’s AirSpace hangar (above).


We’ve arranged a deal with Hinxton Hall, at the Wellcome Genome Campus Conference Centre. Rooms are £81+ VAT including breakfast and based on single occupancy and double occupancy is £98 + VAT per night.

Pioneering the Third Age of Aviation
by Mark Boden of Rolls-Royce

Rolls-Royce is continuing its tradition of ‘pioneering the power that matters’ by developing the systems and components necessary to enter the third age of aviation – the electrical age. This presentation will give an overview of the strategy and the projects that are making this a reality, including ACCEL – the world speed record attempt for all electric flight and E-Fan X – the hybrid electric flight demonstrator.

Development of a Range Extender Engine for Drones, Utilising a Very High Speed MGU
by Dean Evans of NEMA Ltd

The market for drones is expanding faster than the legislation and regulations can keep up with. The state of New York in USA has developed a 50 mile corridor for carrying out qualification testing on drones, including out-of-sight testing. The state has also initiated a stream of funding through Genius NY specifically focussed on developed drone technology and regulations. This talk presents the full prize winners of 2018 Genius NY, Sentient Blue, and what has been developed. The technology utilises a very high speed motor generator unit to generate power whilst in flight by burning fuel through a micro-gas turbine. This increases the range of current drones from 20 mins flight time to 8 hours between refuelling. The talk will also mention some of the testing and regulations that have been coming out from this R&D fund, and look at future potentials.

Aircraft Electrification – Motor Construction and Materials for High-Efficiency
by Sami Ruoho of Arnold Magnetic Technologies

Low weight and high power density are decisive targets when designing motors for electrical aircraft. These targets can be achieved by using high-performance materials in optimised arrangements. The presentation discusses high-performance SmCo and GBD-NdFeB magnet materials enabling the highest performance at elevated temperatures. It will also cover the use of laminated magnets to reduce eddy-current losses in rotors and Halbach magnet arrangements to optimize performance. To maximize the stator efficiency, the benefits of thin-gauge silicon steel will be demonstrated.

Electric Motors and Drives for Air Race E Aircraft Racing
by Jeff Zaltman / Richard Glassock of Air Race E

The University of Nottingham and Air Race E are creating a prototype Formula 1 Air Racing aircraft which will use pure-electric propulsion. Air Race E is committed to pushing technology for speed, performance and power management to provide a platform for development and promotion of cleaner, faster and more advanced electric propulsion for civil aerospace applications. The University of Nottingham’s £13m Beacons of Excellence program, which addresses responses to global challenges including sustainable travel has sponsored a two phase project which will harness developments of new materials, components and technologies aimed at the whole field of electric aerospace propulsion. Phase one uses commercially available equipment, while the second phase will develop a bespoke power system. This presentation details the progress on the retrofit of a Cassutt III air racing aircraft with an electric motor, power electronics and battery system.

Magnetic Materials for Future Aviation
by Niklas Volbers of Vacuumschmelze GmbH & Co KG

Electric flight requires the very best magnetic materials in order to obtain highest power-to-weight ratios. The presentation outlines the most recent state of the art in both soft magnetic and permanent magnetic materials. For stator and rotor, CoFe is the material of choice, enabling highest power-density, efficiency and optionally high strength. For permanent magnets, Sm2Co17 and Nd2Fe14B with grain boundary diffusion offer the highest energy product for increased operation temperatures. In addition, challenges and opportunities regarding the production process are discussed.
