10:00 Uhr - NASA X-57 electric propulsion technology flight demonstrator development and progress
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 Uhr - 11:00 Uhr - Break

11:00 Uhr - 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.

11:30 Uhr - Progress on the Fokker 100 hybrid-electric centreline propulsor demonstrator
Simon Taylor, chief technologist, GKN Fokker, NETHERLANDS
An introduction is provided to the work performed and in progress within GKN on the Fokker 100 Hybrid-Electric (HE) Demonstrator programme. The purpose of this programme is to enable the development and demonstration of HE technologies at full scale on the Fokker 100 (100-seat) regional jet. The modified aircraft uses a centreline propulsor configuration which, in addition to the energy cycle benefits, ingests the boundary layer and junction effects related to the fuselage. Initial results of the programme are presented and an insight into the ongoing work is provided.

12:00 Uhr - Comprehensive modelling and experimental investigations of electric-VTOL aircraft

13:30 Uhr - Robust TeDP electrical microgrid for vehicle thrust and yaw control
Stephen Long, system architect, systems design integration, Rolls-Royce, USA
This presentation will discuss the sensitivity of TeDP electrical microgrid size and efficiency to air vehicle fault accommodation and flight control requirements. The efficacy of various alternative configurations will be discussed and compared in terms of their ability to meet the vehicle needs. Candidate architecture alternatives will include AC and/or DC microgrid. The viability of TeDP is heavily influenced by the protection strategy and reconfigurabilty of the system.

14:00 Uhr - Raising ambition: technologies for hybrid and electric aircraft
Mark Scully, head of technology - advanced systems and propulsion, Aerospace Technology Institute, UK
A number of key technologies are being developed in aerospace to enable a future hybrid and electric commercial aircraft. Key opportunities to demonstrate the technologies and their integration in a system of systems will be important to create the required maturity for consideration in future aircraft. To this end, the role of virtual integration will be increasingly important to provide clarity on benefits and risks of these technologies.

14:30 Uhr - 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 Uhr - 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.

15:30 Uhr - 16:00 Uhr - Break

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

16:30 Uhr - 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 Uhr - Electric engine certification
RĂ©gis 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 Uhr - Electrification and hybridisation – what aviation can learn from automotive
Simon Krueger, project manager, electric and hybrid aviation team, 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.

Room B

13:30 Uhr - Development of a solar-powered stratosphere UAV in Korea
Dr Seokmin Ahn, principal researcher, Korea Aerospace Research Institute, KOREA
Korea Aerospace Research Institute has developed solar-powered UAVs since 2010. Elementary technologies were developed and tested individually for the first three years. 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 Uhr - 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 Uhr - 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 Uhr - 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 Uhr - 16:00 Uhr - Break

16:00 Uhr - 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 Uhr - 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 Uhr - 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 Uhr - 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.

10:30 Uhr - 11:00 Uhr - Break

11:00 Uhr - Electric contra-rotating propulsion system for light aircraft
Nicholas Sills, founder, ContraElectric Propulsion Ltd, UK
Contra-rotating propeller systems have proven and significant benefits over same horsepower single-propeller systems, particularly by eliminating yaw. However, piston- or gas turbine-powered systems are mechanically complex and extremely expensive. New electric motor architecture offers the opportunity to design simple, gearless and affordable coaxial contra-rotating systems for light aircraft. ContraElectric Propulsion Ltd has designed and built a 225kW twin-motor system and, in collaboration with Hercules Propellers Ltd, developed the special propeller sets necessary to match motor performance characteristics. Ground testing is complete and flight testing will commence in a specially built FURIO aircraft.

Prof Philip Mellor, professor of Electrical Engineering, University of Bristol, UK
Dr Mircea Popescu, chief design engineer, Motor Design Ltd, UK
The JTI CleanSky ELETAD project investigated the feasibility of powering the tail rotor of a helicopter with an electric drive, replacing the current mechanical system comprising high-speed shafts and gearboxes. The programme has led to successful ground testing of a high-integrity electric tail rotor drive for a medium twin-engine helicopter. An electro-thermal design tool for such machines has been established, which can accurately model temperatures over representative mission cycles and predict the thermoelectric degradation of the winding insulation system. The presentation offers an overview of the design drivers and modelling tool development, and will be accompanied with test results taken from the full-scale electric tail rotor drive.

14:30 Uhr - How high-performance hybrid supercars can drive aeronautical EV technology development
Justin Almeleh, programme manager, Motivo Engineering, USA
Ever since the introduction of the NACA duct to the automotive world, technology has typically transferred from the aeronautic to automotive industries. With the advent of hybrid powertrains being used by supercars to increase performance rather than efficiency, recent electric vehicle (EV) powertrain development has focused on increasing power-to-weight ratios. Given that the high-level system architectures of an EV aircraft and an EV supercar are markedly similar, there is a unique opportunity for the aviation industry to leverage much of the cutting-edge technology currently being developed in the automotive industry.

15:30 Uhr - Electrical contra-rotating boundary layer propulsion in Fuselage mounted tailplane
Nelson Cámara Aguiar, R&D advanced consultant, Aeronautics, Space and Defence Division, Altran, SPAIN
In the present study developed by Altran ASD I + D Spain, we focused on the energisation of the boundary layer of the conventional single-aisle transport aircraft rear fuselage by the integration of electrical counter-rotating propeller in the tail end zone in one configuration. 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.

16:00 Uhr - 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.

16:30 Uhr - 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.
