2016 Konferenzprogramm

Tag 1

Mittwoch 9 November

09:00 Uhr - 12:30 Uhr - Keynote Presentations
Room A

Prof Josef Kallo, head of energy systems integration, Deutsches Zentrum fĂĽr Luft- und Raumfahrt (DLR), GERMANY

09:00 Uhr - Electric flight in Airbus Group
Mark Cousin, head of group demonstrators - Airbus CTO, Airbus Group, FRANCE
Airbus Group is committed to environmentally friendly aircraft: greatly reduced carbon emissions in flight and on the ground, significant in-flight noise level reduction, hybrid engine is quieter than conventional aircraft engines, additional noise reduction benefit thanks to an electric taxiing system. We view electric aircraft as the future, to provide a possible alternative to fossil fuels over the next 30-40 years. The E-Fan technology demonstrator 1.2 is a hybrid-electric/gas version of the original, all-electric technology demonstrator originally developed in 2011. The hybrid version of the technology demonstrator incorporates the following key changes and technologies: extended flight time, and gas/electric engine.

09:25 Uhr - Bridging the technology gap for hybrid-electric propulsion
Mark Husband, lead engineer - electrical systems and technologies, Rolls-Royce plc, UK
This presentation discusses the potential aerospace journey towards hybrid-electric aircraft and the associated power and propulsion systems. The industry and business challenges will be presented as well as the technical key enablers required to deliver a more integrated solution. The key power and propulsion enablers include an integrated boundary layer ingestion (BLI) propulsion system and hybrid-electric gas turbines. The electrical system is the enabling interconnecting technology that delivers the integrated solution. The presentation will discuss the current state of the art, future trends in electric technology and routes to close the gap for aerospace applications.

10:15 Uhr - 10:45 Uhr - Break

10:45 Uhr - Electric propulsion systems for aircraft
Dr Frank Anton, executive vice president eAircraft, Siemens Corporate Technology, GERMANY
One of the biggest challenges will be in achieving a sufficiently high power to weight ratio for the drive system. The power electronics, electric motors and generators will need to improve by a factor of 10 over and above what is possible today.Siemens last year unveiled a 50 kilogram electric motor with a power output of 260 kilowatts, or enough to power a 2-tonne, four-seat electric aircraft when used in conjunction with a small jet engine.Since then the company has begun installing the motor into a flying test bed, in order to investigate how it performs in flight. The technology is also being scaled up to larger motors of around 1MW, as part of the collaboration with Airbus.

11:10 Uhr - Considerations for next generation propulsion and integrated systems
Neil Garrigan, senior program manager, electrification, GE Global Research, USA
An increasing demand for propulsion system performance improvements together with a desire for reduced development times & costs, decreased maintenance and sustainment costs may lead to fundamental architecture changes to next generation propulsion systems. Additionally trends in electrification, vehicle energy management, data/analytics, and integrated systems can further impact the design and development of future propulsion systems. This presentation will examine these considerations and the next steps for future propulsion & integrated systems.

11:35 Uhr - Towards hybrid-electric propulsion – Safran’s view
Dr Pierre-Alain Lambert, head, energy & propulsion, Safran Tech, Safran, FRANCE
The ACARE goals for emissions reduction of air transport might not be realised without the introduction of some degree of electrification for energy generation and power distribution. In keeping with the idea of providing an evolutionary pathway beyond today’s more-electric aircraft, we will discuss architectural and technological challenges associated with hybrid-electric propulsion, as viewed from the perspectives of a Tier 1 equipment supplier and a propulsive system integrator. Highlights covering several research programmes currently under way at Safran will be shown, ranging from multi-source non-propulsive energy generation for SMRs, up to longer-term disruptive propulsive architectures, through intermediate concepts based on parallel hybridisation of gas turbines.

12:00 Uhr - Q&A With Keynote Speakers

12:30 Uhr - 13:30 Uhr - Lunch

13:30 Uhr - 15:25 Uhr - The Path Towards More-Electric Aircraft
Room A

Neil Cloughley, managing director, Faradair Aerospace Limited, UK

13:30 Uhr - Electrical-variable engine (EVE) hybrid propulsion system: performance impacts and technology sensitives
Michael Armstrong, vision systems lead, Rolls-Royce North American Technologies, USA
This presentation will discuss improvements that are enabled by an electrical-variable engine (EVE) hybrid gas-electric propulsion system. The EVE implements a supplementary electric drive system that provides an optimal electrical motive force to the engine’s fan shaft for the aircraft’s current mission and mission state. The power and propulsion system was developed to minimise operating cost, fuel burn and energy consumption at the vehicle fleet level. The paper will discuss the key performance parameters that were evaluated in terms of a cumulative impact over the vehicle's entire payload range and operational envelope while considering the frequency of specific missions.

13:55 Uhr - Introduction to Aerospace Technology Institute and electric and hybrid technology
Mark Scully, head of technology - advanced systems & propulsion, Aerospace Technology Institute, UK
The Aerospace Technology Institute (ATI) is the objective convenor and voice of the UK’s aerospace technology community. We define the national aerospace technology strategy, and work closely with Government and industry to direct joint funding into aerospace R&T projects that align with the strategy. Key strategic challenges in electric and hybrid aerospace technology target the following: MEA/AEA architectures and thermal management; component technologies, ranging from electronic device capability and power electronics capability, to electrical machines and advanced electrical networks; the development of processes and tools for developing and optimising future generations of electric and hybrid aircraft.

14:20 Uhr - Scaling of electrical power systems for hybrid-electric aircraft propulsion
Prof Peter Malkin, strategic research advisor, Newcastle University, UK
The scaling in size/power levels of electrical power systems is highly non-linear in terms of weight, volume and complexity. This means that the design and approach to multi-megawatt power systems differs from those at, say, 10s or even 100s of kWs. This is particularly significant for aircraft applications. To illustrate the point, three designs will be chosen at 500kW, 1.5MW and 10MW to illustrate these differences, which represent small, medium and large aircraft power systems. Note that the latter will be a fully superconducting network, which presents radically new opportunities and challenges in this field.

14:45 Uhr - Integration for electric and hybrid-electric aircraft
Simon Taylor, chief technologist, Fokker - GKN Aerospace, NETHERLANDS
This paper addresses the trends and needs of the air vehicle and its powerplants, which are driving towards increasing integration and electrification of function. Case studies from within both Fokker and GKN Aerospace are introduced, demonstrating the technology maturation from today's most-electric aircraft towards the aircraft of the future. The focus of this work is in incremental improvements and also setting the path for the disruptive integration technologies of tomorrow. These include architectural choices, more-electric ice protection and detection systems, natural and hybrid laminar flow, structural margins and morphing structures.

NASA has been investing in research efforts to define potential vehicles that use hybrid and turboelectric propulsion to enable savings in fuel burn and carbon usage. This paper gives an overview of the fundamental building blocks that have been derived from those studies, and details what key performance parameters have been defined, and what key ground and flight tests need to occur, and highlights progress towards them.

16:20 Uhr - Superconducting turbo-electric propulsion system as enabler of future hybrid aircraft
Dr Dmitry Melyukov, project manager, Airbus Group Innovations, RUSSIA
The development of next-generation greener and more energy-efficient aircraft is related to the application of some disruptive concepts (e.g. airframe integrated distributed propulsion, powerplant hybridisation, etc.) while existing design and aerodynamic schemes are close to exhausting their improvement potential. This approach leads to the necessity for an intermediate flexible energy management system between turbine(s) and multiple propulsors with the possibility of energy storage, recuperation, etc. Such a system based on electricity seems to be the most suitable. Taking into account size and weight requirements, superconductivity becomes an enabler of the whole described paradigm.

16:45 Uhr - Structurally functional design of a full electric aircraft power complex
Prof Sergey Khalyutin, CEO, NaukaSoft LLC, RUSSIA
Electrification allows optimising an aircraft's power conditions, but complete elimination of the adverse ecological effects of gas-turbine and internal combustion engines is impossible. Transition to aircraft with electrical propulsion systems is a cardinal solution of this task. NaukaSoft has carried out design engineering of a multipurpose aircraft and UAV with electric propulsion. The structurally functional conceptual technology of the full-electric and hybrid aircraft was developed by a group of company scientists. The technology includes optimisation of the power indicators of every aircraft element, proceeding from the general laws of energy transformation and conservation on the basis of power invariants implementation.

17:10 Uhr - Model-based sizing and analysis of hybrid-electric propulsion architectures
Alexander Schneegans, managing partner, PACE Aerospace Engineering and Information Technology GmbH, GERMANY
The presentation addresses three main challenges for the evaluation of hybrid-electric aircraft concepts: provision of an appropriate level of detail for modelling of the battery’s characteristics, determination of the optimum level of hybridisation along the design mission, and assessment of the impact of new propulsion architectures at the overall aircraft level. The implementation of a rechargeable battery model, which captures the dynamic charging and discharging behaviour, and its application within a hybrid-electric propulsion architecture, is demonstrated using the commercial aircraft and systems architecture design platform Pacelab SysArc. A sample propulsion architecture is designed for an existing commuter aircraft.

17:35 Uhr - Impact of electric aircraft on thin-haul commuter aviation operations
Prof Brian German, Langley associate professor, Georgia Institute of Technology, USA
Emerging battery and hybrid-electric aircraft concepts offer the potential for dramatic operating cost reductions for commuter airlines. This talk will describe a study of operational strategies for integrating electric aircraft into existing route networks. Considerations include cost of electricity based on local utility rates, implications of battery charging on airline schedule and aircraft utilisation, and payload-range performance tradeoffs based on optimal use of serial hybrid range extenders.

Mittwoch 9 November

13:30 Uhr - 18:10 Uhr - Alternative Aircraft Design & Technology
Room B

Regis Rossotto, project certification manager - electric/hybrid propulsion, EASA, GERMANY

13:30 Uhr - Fuel cell hybrid power modules for aircraft applications
Prof Josef Kallo, head of energy systems integration, Deutsches Zentrum fĂĽr Luft- und Raumfahrt (DLR), GERMANY
Several governing bodies and aviation organisations have envisioned alternative propulsion scenarios for future aviation. Fuel cell/battery hybrid-electric aircraft are some of the most promising candidates available. Serving as a test platform for these drivetrains, Hy 4 is the next step en-route to emission-free all-electric regional aircraft. The presentation will introduce fuel cell hybrid operation research conducted with this aircraft, detailing improvements over current state-of-the-art lab operation. As a technology transfer path to mitigating aviation’s footprint, this presentation will also discuss a fuel cell-based multifunctional APU replacement for Airbus A320 type aircraft based on testing.

13:55 Uhr - Aircraft design for hybrid-electric flight
Prof Andreas Strohmayer, professor, Institute of Aircraft Design, University of Stuttgart, GERMANY
Electric propulsion offers the opportunity to deviate from today's conventional aircraft configuration with respect to the integration of the propulsive system, thus improving performance characteristics or even providing novel operational features. For the power system, depending on type of aircraft and mission, the aircraft designer has to make an educated choice between a fully electric system and hybrid systems at variable degrees of hybridisation. On the other hand, the size of the electric drive allows for a variety of installation positions, which may lead to distributed propulsion concepts with attractive aerodynamic and propulsive efficiency.

14:20 Uhr - DACAPO (Distributed Autonomous Cabin Power) – the energy-autonomous cabin
Ronny A Knepple, head of energy systems, Diehl Aerospace GmbH, GERMANY
The path towards more-electric aircraft requires innovative solutions for future energy supply concepts. Efficient, quiet and emission-free fuel cells, powered by renewably produced hydrogen, are favourites for this approach. However, the introduction of a fuel cell-based energy supply requires the skilful integration into the aircraft infrastructure. Therefore in this paper, a de-centrally powered, energy-independent, so-called DACAPO cabin is presented. An approach and a first, feasible step for an alternative energy supply on board could be energy-autonomous galleys. MAGIC galleys are self-supporting, and may significantly relieve the onboard electrical system.

14:45 Uhr - Delft University Unconventional Configuration (DUUC) concept aircraft with propulsive empennage
Dr Mark Voskuijl, assistant professor flight mechanics and propulsion, Delft University of Technology, NETHERLANDS
The faculty of Aerospace Engineering at Delft University of Technology has developed a unique and sustainable aircraft concept, the Delft University Unconventional Configuration (DUUC). The concept features a propulsive empennage by replacing the tail with two large ducted fans. The combination of the functionalities of the propulsion system, horizontal/vertical stabilisers and control surfaces predicts a more fuel-efficient design than conventional configurations. To reduce fuel consumption even further, a hybrid-electric propulsion system is integrated in the DUUC aircraft. It will be shown that maximum fuel reduction is achieved when the hybrid-electric aircraft is designed for a short-range mission.

15:10 Uhr - Electric drives for electric green taxiing systems
Ondrej Kotaba, senior scientist, Honeywell International s.r.o., CZECH REPUBLIC
Honeywell Aerospace and Safran demonstrated substantial progress for developing an electric green taxiing system (EGTS) in a joint initiative. Considerable analytical and design work has already been completed, culminating in a demonstration at the Paris Air Show (PAS) in 2013. The EGTS has been installed on an A320 aeroplane that uses APU-generated electric power to provide propulsion to two wheels of the main landing gears. The main advantages of such a system are reduction of fuel consumption and audio noise, reduction of CO2, carbon and nitrous emissions and fast-turn time savings by elimination of the ground tractor for pushback operation.

16:55 Uhr - Feasibility study on hydrogen and electric aircraft compatible with hydrogen society
Dr Takayuki Kojima, associate senior researcher, Japan Aerospace Exploration Agency, JAPAN
Hydrogen is one of the future energies that promise the reduction of CO2 emission and sustainable growth of society. In this paper, 17 aircraft concepts are compared so that the main feature of each component can be obtained. Surveying current and future technologies, 17 concepts are selected by coupling each fuel component (jet fuel, gaseous hydrogen, liquid hydrogen and battery), conversion to electric power (gas turbine, PEFC fuel cell, SOFC fuel cell), electrical power transfer (superconducting motor, normal conducting motor). As a result, it is shown that liquid hydrogen is a promising future energy source for aviation. Aircraft performance of future electric aircraft using liquid hydrogen and PEFC will be almost the same as that of conventional jet engine propulsion.

17:20 Uhr - Model-based systems engineering (MBSE) from concept to takeoff
Frederic Chauvin, A&D industry solution experience director, Dassault Systèmes, FRANCE
To accelerate the development, integration and maturity of new technology for future electrical and hybrid aircraft from concept to takeoff, this paper will outline a model-based approach for maintaining consistency between requirements (customers, business, regulation), systems 3D layout definition and digital mock-up for preliminary and detailed design. The approach will show how collaboration between systems architects and discipline experts, supported by a system digital mock-up (S-DMU), allows upfront definition and validation of structures and systems matching requirements.

11:25 Uhr - A techno-economic perspective of a turboelectric distributed propulsion aircraft
Dr Devaiah Nalianda, lecturer in Gas Turbine Engineering & Technology, Cranfield University, UK
Challenging goals have been set for modern aviation, necessitating revolutionary new aircraft. Incorporating novel technologies, including superconductivity, distributed propulsion and boundary-layer ingestion, shows significant performance benefits. However, the aircraft is a commercial product, and its economics are as vital to the viability assessment as technological performance. Utilising a techno-economic environmental risk assessment framework, and based on the N3X aircraft as a case study, the study demonstrates the application of a novel methodology to assess the sensitivity of operating cost to changes in acquisition and maintenance cost. It goes on to present the likely range of purchase and ownership costs.

11:50 Uhr - Powerful redundant engines for electrically powered aircraft

Technologies on the more-electric aircraft/more-electric engine are still being improved and developed. These technologies continue to evolve and will be built up to future aircraft propulsion systems, such as hybrid propulsion with gas turbine and electric power. In general, advancements in electric machines and batteries are key technologies for future hybrid/electric propulsion. Moreover, integration and management among thermal system, electric and propulsive power is mandatory, although there are challenges to be overcome beyond the MEA/MEE technologies. Approaches towards future hybrid propulsion systems are discussed.

14:20 Uhr - Disruptive electric machine technology for aircraft propulsion
Carl Goodzeit, consulting engineer, Texas Consultants, USA
A new type of radial field electric motor/generator is described based on a dual-armature topology that provides a factor of two increase in specific power.

In addition to the design and development maturity of the device, we discuss two applications. The first is a short-range commuter aircraft powered by advanced lithium batteries with 1,200kW propulsion motors having a specific power that emulates their turboprop counterpart. The second case is a 3,700kW machine suitable for a large transport aircraft that also matches the specific power of its turboprop counterpart.

14:45 Uhr - Specific items of Li batteries in respect to certification
Carlos Javier Munoz Garcia, new electrical technologies expert, European Aviation Safety Agency (EASA), GERMANY
As with any relatively new technology or novel use of a technology, there is very limited experience regarding the use of lithium batteries in aviation applications and especially in electric/hybrid propulsion. Lithium batteries have specific failure, operational and maintenance characteristics that differ significantly from conventional batteries currently covered by Aviation Certification Normative. Therefore, appropriate new certification materials and new qualification standards for lithium battery installations have been established to ensure that these battery installations do not have hazardous or unreliable design characteristics. The presentation will give an overview of the certification materials and qualification standards for rechargeable lithium batteries.

15:10 Uhr - 15:40 Uhr - Break

15:40 Uhr - Electrical machines for hybrid aircraft propulsion
Dr Chris Gerada, professor of Electrical Machines, The University of Nottingham, UK
Going to airborne hybrid propulsion systems will require a new generation of electrical machines and drives able of a step change in power rating and power density compared with existing technology. Shorter-term targets are likely to be achieved through advancements in non-superconducting technologies; longer-term targets are more likely to be met through superconducting technologies or through a new generation of electrical machine constituent materials. This presentation will first highlight the main challenges and requirements for electrical machines for hybrid aircraft, including those for generator sets and propulsion. It will then review recent developments in pushing the boundaries of electrical machine performance for airborne applications through new electrical machine-drive topologies, the application of new materials, advancements in health monitoring algorithms and faster-switching power electronics.

Felix von Borck, executive managing director, Akasol GmbH, GERMANY
We have seen first projects where batteries have been used for hybridisation and electrification of aerospace applications. Due to the low performance of the batteries, the targets of fuel efficiency, availability, safety and robustness could not always be achieved. On the other hand, high-performance batteries have been successfully used in more demanding applications such as commercial vehicles, buses, rail and mining machines. When these technologies and products are considered for aerospace applications, new solutions such as pure-electric drives or hybrids with extended electric range will become the first option for the decision makers.

10:45 Uhr - Progress in state estimation for lithium-ion batteries
Matthias Vetter, head of department, Fraunhofer Institute for Solar Energy Systems ISE, GERMANY
Battery management systems are the key components for efficient, safe and durable operation of lithium-ion batteries. In this context, precise determination of the actual status of the battery cells is still challenging, especially for very promising new cell technologies. This presentation will give a short overview of the challenges and state-of-the-art methods for state-of-charge and state-of-health determination. In addition, a new algorithm for precise determination of the inner states, the so-called particle filter, will be explained. Finally, achieved results for different stationary and mobile applications and different cell chemistries will be presented.

11:10 Uhr - Advanced embedded platforms and IMA for distributed power controls
Jacques Gatard, director sales aerospace Europe, TTTech, AUSTRIA
Distributed power generation in modern aeroplanes requires seamless coordination and deterministic communication between the individual power electronic modules and a supervising unit that will control the load assignments depending on the power demands of the individual aircraft systems and flight phases. Complex distributed power generation controls can integrate up to 100 computing modules, and systems can span the whole aircraft and wings (e.g. Boeing 787). We discuss how the perimeter of next-generation IMA architectures can expand and host distributed power functions. As a consequence, future optimisation in design of integrated systems for more-electric aircraft is accomplished.

11:35 Uhr - Modular electric power systems for aerospace vehicles
Gregory Semrau, systems engineer, Moog Inc, USA
As battery technology has matured, the focus has been on increasing energy density; power density has not been a primary driver except for niche markets. Flight control surfaces are a primary example of a power-dense application. MEPS, a packaging of ultracapacitors to allow inclusion in a power system, offers several advantages for high-power-density aerospace applications because of the large instantaneous discharge capability, high cycle life and fast recharge capability. Including this power buffer will decrease the transient load on a central generator or battery system, decreasing the total power system volume and mass.

12:00 Uhr - Adaptive dual-spool power system architecture – challenges, solutions and benefits
Manish Dalal, executive director – electrical power systems, GE Aviation, USA
The electric power required on a future aircraft is expected to increase dramatically to megawatt levels for commercial and military applications. The increase in electric power extraction in commercial application is driven by plans to use hybrid-electric propulsion to realise reduced fuel consumption and higher efficiency. This paper will outline the adaptive power system architectures with dual-spool power extraction, torsional oscillations and similar mechanical issues caused at higher power level extraction and proposed solutions. It will also discuss dual-spool controls challenges and proposed solutions to optimise power system and engine performance in extracting megawatt electric power levels from turbine engines.

The Hybraero H600 is a next-generation hybrid propulsion system for general aviation, capable of delivering 600hp in combined power, utilising a new clean sheet designed JetA1 (or biofuel) fuelled internal combustion engine (ICE) and twin electric motors, combined into a single hybrid propulsion system. The engine is designed to sit within the footprint of existing six-cylinder Avgas engines, able to be fitted to new-build or retrofitted to existing fleet aircraft. Created by Faradair Aerospace and motorsport engineering firm Prodrive, the Hybraero H600 is the most powerful and innovative hybrid propulsion system for the general aviation sector; it will begin testing in 2017.

14:20 Uhr - Hypstair: the world's first certifiable serial hybrid-electric powertrain for general aviation
Dr Tine Tomazic, director of R&D, Pipistrel d.o.o. Ajdovscina, SLOVENIA
Project Hypstair resulted in the development of the world's first certifiable serial hybrid-electric powertrain for general aviation class aircraft. In the project, special attention was paid to the architecture of the powertrain, reliability, redundancy, extreme lightweight design, cockpit indications and propeller interface. Alongside the main development effort, an engineering simulator was developed to predict the powertrain's effect on mission profiles. A haptic power-lever was also introduced and demonstrated as part of powertrain ground tests.

15:30 Uhr - Cockpit displays for electric and hybrid aircraft
Steven Jacobson, senior vice president, product development, Avidyne Corporation, USA
Electric and hybrid propulsion aircraft require optimisation of both the display design and the pilot interface design. Avidyne has been optimising displays and sensors for this emerging aircraft market. Some recent design flight testing results and in-development displays and user interface will be presented.

15:55 Uhr - Model-based system performance simulation analysis for hybrid-electric aircraft
Nir Kastner, research associate, German Aerospace Center (DLR), GERMANY
We present a generic modelling framework for hybrid-electric powertrain architectures for performance assessment. It results from the PowerLab research project, which is a collaboration of industry and academics. Aiming for small passenger aircraft, the feasibility of hybrid-electric powertrains is examined. The benefits of Modelica as a modelling environment are explained, followed by a survey of the modelling assumptions behind the powertrain components. The subject of mission performance demands is discussed, with emphasis on flight safety and regulation fulfilment. Finally, results are presented for an optimisation study for different powertrain architectures, and an outlook on future development is given.

16:20 Uhr - Real-time simulation tools for more-electric aircraft power system development
Dr Ravinder Venugopal, executive director, US technical services, Opal-RT Corporation, CANADA
The drive to optimise aircraft operating costs has led to a focused effort to replace certain hydraulic, pneumatic and mechanical systems with electrically driven ones, thus creating 'more-electric' aircraft (MEA). However, realising MEA involves considerably increasing the level of onboard power along with the development of complex power electronics and advanced control systems. Specifically, power quality is of particular concern. Real-time simulation is a key tool for developing and validating these advanced power systems at the aircraft level; however, fast dynamics and complexity pose computational challenges.
