MARKET INSIGHTS Sustainability and Growth: Tackling Emissions in the Aerospace Industry MARKET INSIGHTS Sustainability and Growth: Tackling Emissions In The Aerospace Industry Prepared by: Sustainability and Growth: Tackling Emissions In The Aerospace Industry The aerospace industry has taken proactive and bold steps to dramatically reduce emissions by 2050. In fact, through the ICAO-led program, CORSIA (Carbon Offsetting and Reduction Scheme for International Aviation), the global industry has committed to reducing the international flight emissions to 50% of the levels experienced in 2005. With 21 years to the self-imposed deadline, the aerospace industry is working on three pillars to attain the goal: emissions reporting, emissions mitigation and emissions offsetting. The greatest gains in reducing emissions will come from the technology being developed to achieve alternative propulsion, produce biofuels and fly zero fuel aircraft. In November 2019, the global aerospace industry descends on the UAE for the Dubai Airshow where a key focus is on maintaining the expected growth in air travel whilst simultaneously reducing emissions. It is apropos as Dubai is set to be the epicentre of future passenger movements and the largest aviation megacity in the world. KEY POINTS • Electric and hybrid-electric engines are considered the leading option to zero or low emission flight • Hydrogen engines are under development as a zero-emissions engine alternative • Airlines and aircraft OEMS are working on efficient combustion engines to reduce fuel burn and emissions by up to 5% • The fully electric aircraft market will be worth USD$45 billion by 2025 and there will be 200 projects underway by the end of 2019 • Airbus’ R&D spend is €3.2 billion and focuses on aircraft design to increase fuel efficiency and support electrification • Boeing’s ecoDemonstrator 777 aircraft will undertake tests of 50 new technologies to support sustainability • The global aviation fuel market will be worth USD$450 billion in 2026, 5% of which will be SAF (Sustainable Aviation Fuel) • Etihad undertook a flight in 2019 fuelled entirely by SAF produced from local desert plants • As an aerospace city of excellence, Dubai and the Dubai Airshow will play a critical role in future sustainability Whilst ICAO acknowledges the importance of emissions reporting and offsetting, the real gains in reduction will come from mitigation. Mitigation comes through many avenues: propulsion, aircraft design and fuel. PROPULSION A number of manufacturers and airlines are working on alternate propulsion concepts to reduce carbon and nitrogen oxide emissions. Concepts range from full electric to hybrids, and engines which operate on hydrogen. Each option represents risks and benefits on a scale which balances environmental impact and commercial reality. [email protected] www.dubaiairshow.aero @DubaiAirshow Sustainability and Growth: Tackling Emissions In The Aerospace Industry ELECTRIC ENGINES A recent study from United Technologies Corporation, whose businesses include Collins Aerospace and Pratt and Whitney, indicated the commercial application of electric engines could reduce noise by 85% and reduce operating and maintenance costs by up to 20%. The same report showed a hybrid-electric engine improved fuel consumption by 40% and reduced carbon emissions by more than 20%. As the technology is well established in the automobile industry, it is considered the forerunner for emissions reduction. There are a number of large and small players working with the technology. On the north west coast of North America, magniX has partnered with regional carrier, HarbourAir, to retrofit electric engines to their De Havilland DHC-2 Beaver aircraft. This is a solution designed for flights less than 1000 nautical miles and to work on improving existing platforms. The larger players are also entering the electrification fray with solutions for new aircraft and longer flight paths. In late 2019, Norwegian airline, Widerøe, announced a joint research project with Rolls Royce into zero emissions aviation. The airline will need to replace its fleet of Dash8 aircraft to one which is capable of being propelled by an electric Rolls Royce engine. The project has the expressed goal of commercial flights by 2030. At roughly the same time, Rolls Royce announced the purchase of Siemens’ eAircraft business which focuses on electric and hybrid-electric aerospace propulsion. Citing the pressures on the industry to reduce CO2 emissions, the English engine-manufacturer is seeking the German-born technology to expand beyond eVOTL to larger aircraft with longer flight parameters. GE Aviation, supplier of nearly 65% of aerospace engines flying globally, announced their hybrid engine in 2015 committing USD$500 million to the project. In 2019, GE Aviation announced a collaboration with XTI Aircraft to power their eVOTL with the hybrid-electric version of their well-established CatalystTM engine. The alliance has generated some confidence as the aircraft has confirmed pre-sale orders. The great challenge with electric or hybrid-electric aviation engines, is the weight to power ratios of the batteries required. In the quest for zero emission and highly efficient propulsion systems, some are turning to hydrogen due to this issue. HYDROGEN ENGINES ZeroAvia, based in the US, is working on an entirely emissions free aircraft with hydrogen cells in the aircraft’s fixed wings. Across the Atlantic, the European Union has backed UK-based universities and industry players to collaborate and research hydrogen as a fuel source. ENABLEH2 aims to fully investigate all concerns of hydrogen engines as a solution: environment, safety, society, commercial and logistics. [email protected] www.dubaiairshow.aero @DubaiAirshow Sustainability and Growth: Tackling Emissions In The Aerospace Industry MORE EFFICIENT COMBUSTION ENGINES Aside from electrification, Rolls Royce have spent 100 million engine hours on extracting the greatest efficiency from the existing Trent engine for the Advanced and Ultrafan versions. Scheduled for delivery in 2020 and 2025 respectively, these new generation engines promise weight savings, 20% improvement on fuel burn, and increases in pressure and bypass ratios all of which offers their operators decreased fuel bills and greater fuel efficiency. It is the fuel saving as much as the emissions reductions which is attracting the attention of the airlines. EasyJet is one such airline who has recognised not only the need for reducing emissions through efficient engines yet also the cost savings from reduced fuel burn from these more efficient propulsion systems. Creating a formal relationship with UK-based Derwent Aviation, the two are working towards commercialising the Dual Drive Booster by 2025 to reduce carbon emissions by 5%, halve the nitrogen oxide emissions, and reduce fuel burn by up to 4% on flights up to 1000 nautical miles. The engines would be retrofitted to the airline’s fleet of Airbus aircraft to service routes into Europe. When fuel is 25% of the airlines operating budget, any efforts to reduce the amount required add to the triple bottom line. AIRCRAFT OEMS As aircraft design is a significant factor in mitigating the emissions generated by the aerospace industry, the major OEMs are taking a lead role in the emissions reduction targets. The electric aircraft is considered the forerunner in the zero emissions race and industry reports predict the 2018 USD$30 billion market size will swell to USD$45 billion by 2025. Aerospace consultancy, Roland Berger, echo this report predicting by the end of 2019 there will 200 electric aircraft projects underway in the world. In the more immediate term, Boeing and Airbus are turning their attention to improving their twinjet aircrafts as reports suggest quad aircraft are 24% less fuel efficient. Airlines are also taking notice as the greatest growth of new aircraft deliveries in the coming two decades are in the narrow bodied, twinjet section of the market as everyone strives for greater efficiencies as passenger numbers continue to climb. In 2018, Airbus spent €3.2 billion on research and development which was an increase of 15% over the previous year. In line with the EU standards and CORSIA, the company publishes its carbon emissions along side its financial results sending a clear message that the two are intertwined. Currently, a keynote initiative for Airbus is E Fan X, a hybrid-electric aircraft being developed with Rolls Royce and Siemens. Initially using a British Aerospace RJ100, the group will remove one turbine engine and replace it with a 2MW hybrid-electric version supported by a bank of batteries. Airbus is using the test aircraft to develop the integration of electrification into the aircraft design. Within another alliance, Airbus is working with Safran and Daher to pioneer a wing mounted hybrid propulsion aircraft. Airbus is managing the aerodynamics of the aircraft; Safran the hybrid and battery systems; and Daher is responsible for the construction and systems integration on their TBM platform. The team is aiming for a 2022 test flight. [email protected] www.dubaiairshow.aero @DubaiAirshow Sustainability and Growth: Tackling Emissions In The Aerospace Industry At the same time, Airbus is working with Scandinavian Airlines to complete a feasibility study on all aspects required for the full or partial electrification of aircraft. The results are due in 2020 and will focus on the ground support and infrastructure required for airlines and airports to welcome electric aircraft for a fully zero emissions operation. Working the problem from multiple angles, Airbus has signed on as the foundation partner of the inaugural Air Race E. The aerial race aims to support up and coming designers, engineers and flight operators to develop full electric aircraft not only to compete but also to provide innovation to the entire industry. Along the same strategic lines, Airbus launched a radical aircraft concept aptly entitled “Bird of Prey”. Like the race, it urges designers to think beyond the standard, seeing inspiration from the natural avian aerodynamics to develop the efficient, low emission aircraft. Boeing spends around USD$3 billion each year on research and development in both in house and external projects.

Abstract: Recently, the new Green Deal policy initiative was presented by the European Union. The EU aims to achieve a sustainable future and be the first climate-neutral continent by 2050. It targets all of the continent’s industries, meaning aviation must contribute to these changes as well. By employing a systems engineering approach, this high-level task can be split into different levels to get from the vision to the relevant system or product itself. Part of this iterative process involves the aircraft requirements, which make the goals more achievable on the system level and allow validation of whether the designed systems fulfill these requirements. Within this work, the top-level aircraft requirements (TLARs) for a hybrid-electric regional aircraft for up to 50 passengers are presented. Apart from performance requirements, other requirements, like environmental ones, Citation: Eisenhut, D.; Moebs, N.; are also included.

  • Preliminary Feasibility Analysis on the Use of Hydrogen Fuel Cells for a Hybrid-Electric Aircraft Testbed
    Preliminary Feasibility Analysis on the use of Hydrogen Fuel Cells for a Hybrid-Electric Aircraft Testbed Evan Gibney Co-op Student National Research Council Canada 1200 Montreal Rd, Ottawa, ON K1A 0R6 [email protected] Overview A lithium-ion battery based powertrain was developed for a Cessna 337G Skymaster under the Hybrid Electric Aircraft Testbed (HEAT II) project at the National Research Council Canada (NRC). As the project approaches its conclusion, a future area of exploration for the HEAT project may be in the integration of hydrogen fuel cells onto the Cessna aircraft. Due to their low carbon emissions and high specific energy density relative to batteries, fuel cells are becoming an increasingly important area of research for the future of low emissions aviation. Fuel cells are expected to play a large role in helping the aviation industry meet the ambitious 2050 target for 50% reduction in carbon emissions relative to 2005 levels. This is evidenced by the significant growth of hydrogen based aviation developments in recent years. Companies such as H2FLY have begun to demonstrate test flights using hydrogen propulsion systems. Additionally, the government of Canada has made clear the importance of hydrogen in the future of Canada’s energy landscape. In December of 2020, a report, titled, “Hydrogen Strategy for Canada, Seizing the Opportunities for Hydrogen, A Call to Action”, was released by Natural Resources Canada (NRCan) outlining the path towards a Canadian hydrogen economy by 2050. The report outlines the need to support further R&D, and encourage “Canadian demonstrations in emerging applications” such as aviation.

    Systems Analysis of Community Noise Impacts of Advanced Flight Procedures for Conventional and Hybrid Electric Aircraft This report is based on the PhD Thesis of Jacqueline L. Thomas submitted to the Department of Aeronautics and Astronautics in partial fulfillment of the requirements for the degree of Doctor of Philosophy at the Massachusetts Institute of Technology Jacqueline Thomas Committee: Dr. R. John Hansman Dr. Mark Drela Dr. Robert H. Liebeck Report No. ICAT-2020-06 June 2020 MIT International Center for Air Transportation (ICAT) Department of Aeronautics & Astronautics Massachusetts Institute of Technology Cambridge, MA 02139 USA 1 Systems Analysis of Community Noise Impacts of Advanced Flight Procedures for Conventional and Hybrid Electric Aircraft by Jacqueline Thomas Abstract Recent changes to aircraft approach and departure procedures enabled by more precise navigation technologies have created noise concentration problems for communities beneath flight tracks. There may be opportunities to reduce community noise impacts under these concentrated flight tracks through advanced operational approach and departure procedures and advanced aircraft technologies. A modeling method to assess their impacts must consider the contributions of aircraft engine and airframe noise sources as they vary with the position, thrust, velocity, and configuration of the aircraft during the flight procedure. The objective is to develop an analysis method to design, model, and assess the community noise reduction possibilities of advanced operational flight procedures performed by conventional aircraft and advanced procedures enabled by future aircraft concepts. An integrated analysis framework is developed that combines flight dynamics and noise source models to determine the community noise impacts of aircraft performing advanced operational approach and departure procedures.
