Sean Clarke, X-57 principal investigator, NASA, USA
NASA's X-57 is an experimental aircraft designed to demonstrate radically improved aircraft efficiency with a 3.5 times aero-propulsive efficiency gain at a 'high?speed cruise' flight condition for comparable general aviation aircraft. These gains are enabled by integrating the design of a new, optimised wing and electric propulsion system. Integrating new technologies into critical systems in experimental aircraft poses unique challenges that require careful design considerations across the entire vehicle system, such as qualification of new propulsors, compatibility of existing systems with a new electric power distribution bus, and instrumentation of newly qualified propulsion system devices.

10:30 - 11:00 - Break

11:00 - Electrification – powering the future of flight
Glenn Llewellyn, general manager, electrification - corporate technology office, Airbus, FRANCE
In 2015, following in the footsteps of Louis Bleriot 100 years earlier, Airbus flew the E-Fan full electric aircraft non-stop across the English Channel. This, and subsequent evolutions of the E-Fan, were the successful beginning of the Airbus electrification roadmap. Since then, Airbus has launched Vahana, a single-seat tilt-wing autonomous electric VTOL at Airbus’s Silicon Valley outpost called A3, as well as CityAirbus, a four-seat octocopter being built in Donnauworth and Munich in Germany. In parallel, Airbus has signed a multi-million investment in 20MW scale hybrid-electric propulsion ground test facilities and a strategic partnership with Siemens. This presentation will share the steps we are taking to prepare for electrification to power the future of flight.

To this end, the role of virtual integration will be increasingly important to provide clarity on benefits and risks of these technologies.

14:30 - Electric power systems for hybrid-electric distributed propulsion – a roadmap
Prof Peter Malkin, strategic research advisor, Newcastle University, UK
Newcastle University was recently awarded funding by the EPSRC to support the UK ATI strategy in advanced systems. Pilot studies have been carried out in key areas to enable the development of hybrid-electric distributed-propulsion aircraft. The studies consisted of medium-voltage (MV) power systems for aircraft, high-temperature superconducting (HTS) power network design and BLI motor studies including a feasibility study of adapting a tail-mounted BLI system for an existing large aircraft. The objective of each of these studies was to produce technology roadmaps and value propositions. These are linked to the timescales and requirements of the civil aerospace industry to facilitate the design and testing of HEDP aircraft from regional up to large long-haul designs.

15:00 - Evolution of fundamental technologies for future electrified aircraft
Dr Ajay Misra, deputy director, research and engineering, NASA Glenn Research Center, USA
Gradual progression of electric and hybrid-electric aircraft from small planes to large planes will require technology advances in multiple areas, which include energy storage, electrical machines, power transmission, power electronics, control systems, materials, thermal management and multi-scale modelling tools. Advances in fundamental research and applied interdisciplinary research will be required to realise the goals for future electric and hybrid-electric aircraft. The presentation will provide an overview of long-range research and technology needs for the next 30 years, and how the evolution of several early-stage technologies will influence the development of electrified aircraft in the future.

This presentation will summarize recent achievements of ongoing projects and introduce the audience to planned programs.

16:30 - Sensing and actuating capabilities of the electric propulsion system
Dr Akira Nishizawa, section leader, Japan Aerospace Exploration Agency, JAPAN
JAXA and the University of Tokyo have collaborated on a new control method utilising the multi-functionality of the electric propulsion system. The electric fan itself functions as a sensor that estimates the air speed. It also functions as a sensor to detect propulsion system faults. Due to the interaction between the wake of the electric fan and the main wing, the electric fan also functions as an actuator for adjusting the lift force. Results of ground and flight tests are shown.

17:00 - Electric engine certification
Régis Rossotto, PCM electric/hybrid propulsion, EASA, GERMANY
The safety requirements for aeronautical combustion engines were able to evolve gradually over decades as service experience pointed to where the most important risks lay. With the introduction of electric engines on aircraft, manufacturers and certifying authorities face new challenges. Due to the fact that their design and their usage are different from those of combustion engines, the certification requirements will have to be adapted to maintain a high level of safety for customers and passengers. How will the certifying authorities approach this challenge?

17:30 - Electrification and hybridisation – what aviation can learn from automotive
Simon Krueger, aerospace consultant, P3 Aviation GmbH, GERMANY
In this presentation the P3 Group will give insights into applying prior experience of the automotive industry in terms of challenges, mistakes and best practices regarding e-mobility to current development in aviation. To successfully electrify and hybridise aviation from a technical as well as an economic perspective, aviation has to learn from related fields such as batteries, electronics, charging, infrastructure and implementation. Special emphasis will be put on the transfer to VTOLs, on-demand mobility and thin-haul commuter aircraft concepts.

Developed technologies have been integrated into aircraft. A total of six versions of UAV have been tested, the smallest one with a wing span of 1.8m, and the largest and the latest with 19.5m. The latest version, named EAV-3, stayed successfully for 1.5 hours at a height of 18.5km. The presentation will outline what has been accomplished and how it has been executed, including flight test results.

14:00 - Systems readiness level maturation of hybrid aircraft
Dr Patrick Norman, lecturer, University of Strathclyde, UK
This presentation will provide an overview of recent activities at the University of Strathclyde, where new end-to-end simulation-based design and experimental testing capabilities have been developed for hybrid-electric aircraft electrical power systems. It will show how these developments recognise the importance of technology and systems readiness level maturation in realising the full benefits of the hybrid aircraft concept, and facilitate collaborative efforts through the provision of remote connection with other design tools and labs.

14:30 - Optimising battery power, energy and weight for aerospace
Gregory Albright, vice president of business development, AllCell Technologies, USA
Many aerospace applications require high energy and high power from batteries. Battery cells that provide enough power sacrifice energy density to achieve high power. More energy-dense batteries will overheat if used for high power, reducing performance and causing safety issues. Specialised phase change materials can help bridge the gap by allowing high-energy cells to be used in high-power applications without overheating. This presentation will present testing and simulation results to illustrate how thermal management can improve net performance.

15:00 - Hybrid turbine solid-oxide fuel cells for more-electric aircraft
Prof Christopher Cadou, associate professor, University of Maryland, USA
This paper describes the design and construction of a prototype engine-integrated solid-oxide fuel cell (SOFC) system for more-electric and all-electric aircraft. The baseline engine is a small (50 lbf thrust) COTS turbojet and the baseline electrical prime mover is a 200W integrated reformer/SOFC cannibalised from an Adaptive Materials APU. The performance of the engine and SOFC is measured and the data used to develop validated models for each. These validated models are combined to create a model of the integrated system that is used to design the prototype.

15:30 - 16:00 - Break

16:00 - Designing electrical power systems for aircraft: an architectural challenge
Dr Jonathan Menu, research engineer, Siemens Industry Software NV, BELGIUM
Increased aircraft hybridisation and electrification represent a next step towards more efficient, greener and safer aviation, but the design questions systems engineers are faced with are only partially addressed by current software tools. We present a methodology and tool that unifies different steps in the design process of electrical power systems. These steps include the automatic generation of system architectures, reliability analysis, controller generation and formal verification by simulation. The solution is generic and can be applied to failsafe design for other systems, including hydraulics, hybrid powertrains and environmental control systems.

16:30 - Status of process technology for type 2G high-temperature superconductors
Manuel La Rosa Betancourt, founder and director, PI Integral Solutions Limited, GERMANY
After 30 years of development, high-temperature superconductors (HTS) have achieved a degree of maturity that makes them suitable to become game changers in the race for developing all-electric aeroplanes. The superconductor industry has entered a phase of growth and economies of scale. Manufacturing technologies enable serial and continuous production of large quantities of wire, coils and magnets. Theva has succeeded in achieving substantial improvements in the performance of gadolinium-based HTS wire, using proprietary developed technology. The maturity level achieved allows commercial supply of products supported by robust processes, high quality consistency and competitive costs.

17:00 - Can we still fly jets and save the planet?
Alex Major, founder and chairman, Green Flight Foundation, USA
In an attempt to reduce carbon emissions and reverse global warming and climate change, the entire transportation industry is transitioning to electric and hybrid electric drive. In this presentation, we unpack the concept of using renewable aviation fuels in the range extender engines proposed for hybrid-electric aircraft propulsion systems, which do not turn propellers, but turn generators that charge battery packs that power electric drive motors that turn propellers. These next-generation renewable aviation fuels will reduce carbon emissions by 85-95%.

17:30 - Liquid hydrogen storage technology for airborne applications
Pierre Crespi, innovation director, Air Liquide Advanced Technologies, FRANCE
Hydrogen fuel cells have been extensively investigated in the past five to 10 years for aerospace applications such as drones and aircraft as power supply sources for auxiliary power or propulsion purposes. Most of these projects rely on high-pressure hydrogen storage devices that display a high maturity level but low gravimetric index. The latter can be dramatically increased due to liquid hydrogen storage technology inherited from space technology. This presentation focuses on liquid hydrogen storage technology for applications like fuel cells on board aircraft.

14:30 - Development of global aviation standards for electric propulsion
Tom Gunnarson, lead of regulatory affairs, Zee Aero, USA
The move towards performance-based aviation regulations using high-level safety objectives includes the incorporation of consensus standards by reference to show means of compliance. Industry has accessed standards development organisations such as ASTM International to bring together stakeholders including authorities, academia and user groups to develop standards for a new wave of codes beginning with FAA Part 23 and EASA CS-23. This presentation will focus on how this new methodology is being put into practice for electric propulsion in general aviation aircraft.

15:00 - 15:30 - Break

15:30 - Evolution in Certification and Applicant Interaction
David Jenson, aerospace engineer, Federal Aviation Administration, USA
The FAA recently updated its part 23 regulations for general aviation airplanes with the intent of having less prescriptive, performance based, rules which will allow applicants more flexibility in showing compliance. These new rules require the applicant to provide a Means of Compliance for the performance based rules, which may utilize consensus standards. Importantly, to the Electric/Hybrid propulsion community; the updated part 23 regulations considered electric propulsion in the new rule making to provide for a more efficient certification of electric propulsion air planes. The FAA is addressing how new technologies are handled. A process has been put in place to evaluate technologies before the application process, to ensure adequate rules and guidance are available.

12:30 - 12:30 - Lunch

Riccardo Frollo, project certification manager, European Aviation Safety Agency, GERMANY

12:30 - Multi-disciplinary design of hybrid-electric aircraft
Alexander Schneegans, managing partner, PACE Aerospace Engineering and Information Technology GmbH, GERMANY
The works presented during the 2016 symposium have been industrialised and made available in an industrially used software product for multi-disciplinary design of aircraft. To this end, battery models and electric motors allow simulation in active and passive mode to account for energy recovery during descent phases. The propulsion model is embedded in a fully fledged environment for multi-disciplinary aircraft design. Its application is demonstrated on the example of a three-engine commuter aircraft whose conventional turboprop engines are sized for cruise condition, with the electric engine providing the additional thrust for take-off and climb under one-engine inoperative conditions.

13:00 - Technology path to megawatt electrical machines for commercial aircraft
Dr Mike Benzakein, AVP, aerospace research, The Ohio State University, USA

14:00 - Comparative Evaluation of the Efficiency of a Regional STOL Aircraft With Distributed Electric Propulsion System (DEPS)
Semyon Mikhalyov, research officer, Central Aerohydrodynamic Institute, RUSSIA
Andrey Dunaevskiy, program manager, Central Aerohydrodynamic Institute, RUSSIA
Parametric studies were conducted to compare the characteristics of a 40-seater regional aircraft with two turboprop engines and 10 additional electric engines with propellers, blowing the wing at take-off and landing to increase the lift. In cruise flight, the propellers of DEPS are retracted into the wing without creating additional drag. DEPS engines are powered by generators installed on gas-turbine, turboprop or turbojet, or from an electric battery. The use of DEPS, additional generators for its power supply and electrical wiring leads to an increase in operational weight. At the same time, propeller effects allows us to increase the lift and reduce the wing area, which leads to improved fuel efficiency.

With horizontal stabiliser located at the height of the fuselage, impact studies have been developed on the aircraft's electrical system, structure and flow irregularities induced by the fuselage and the stabilisers in the efficiency of the propeller in conditions of flight from cruising to Mach 0.78, and measures have been developed to counteract it, and to increase the obtainable propulsive efficiency and its reflection in the reduction of the fuel consumption and improvement of the performances.

15:30 - Problems of electrical aircraft design – efficiency vs. safety
Sergey Khalyutin, CEO, Experimental Laboratory NaukaSoft, RUSSIA
The ability to create electric or hybrid aircraft depends on the efficiency of the electrical power sources and the energy intensity of energy storage. Increasing the energy intensity and energy efficiency leads to a decrease in aircraft safety. The solution is to use a control system that will provide the desired level of safety. Examples of control actions are presented.

16:00 - Hybrid-electric propulsion systems for UAVs
Feriel Samouda, aeronautical engineer, Star Engineering, FRANCE
One challenge in the unmanned aircraft vehicles industry will be achieving a sufficiently high power-to-weight ratio for the drive of the system. One critical aspect in UAV design is the provision of high power with light mass. In addition, research programmes on new transportation mean that the target today is for unmanned aircraft vehicles to be alternatives to conventional transportation solutions, especially regarding their operating cost and environmental impact. This paper discusses some case studies on existing hybrid research programmes in the field of UAVs, regarding technical and certification aspects.
