InnovAtive DeMonstrator for hyBrid-Electric Regional Application (AMBER)

气候变化给当今社会带来了前所未有的挑战。许多研究强调，迫切需要实现全球工业脱碳，并大幅减少包括航空在内的所有行业的污染物排放。尽管由于运营量大，航空业对全球环境的影响主要是由中小型市场飞机驱动的，但在新的使能技术在较小规模或尺寸上逐步成熟之前，无法为此类应用所需的电力需求开发颠覆性技术。支线航空的转型，即，因此，飞行距离为500至1 000公里、最多可容纳100个座位的飞机将引领可持续发展的道路，并将具有特别重要的意义。电池和液氢燃料电池技术都还不够成熟，无法在未来十年内实现全电动支线飞机。相反，需要采取中间步骤，到2035年大幅减少温室气体排放。为支线飞机开发至少50%混合动力的混合电力推进系统代表了这一非常具有挑战性但可实现的中间步骤，并且与2020年最先进的支线飞机相比，可以将使命燃料燃烧减少至少50%。使用100%可持续航空燃料的热力发动机将使生命周期的温室气体排放量减少90%，接近于零。拟议项目AMBER（hyBrid-Electric Regional应用的创新演示器）解决了这方面的问题，并追求混合电动关键部件的成熟和基于燃料电池的具有产品代表性的并行混合电动推进系统架构的验证，用于2035年前具有EIS的下一代支线飞机，以满足SRIA和清洁航空主题电话中设定的雄心勃勃的环境目标。

Climate change poses an unprecedented challenge on today’s society. Numerous studies highlight the urgent need to decarbonize global industry and to drastically reduce pollutant emissions across all sectors, including aviation. Although, the global environmental impact of aviation is mostly driven by small-medium range market aircraft due to the large volume of operations, the development of disruptive technologies for the power demands such applications require cannot be put in place until progressive maturation of novel enabling technologies has been achieved at lower scale or sizes. The transformation of regional aviation, i.e., aircraft serving distances of 500 to 1000 km at a capacity of up to 100 seats, will thus lead the way towards sustainability and will be of particular importance. Both battery and liquid hydrogen powered fuel cell technology will not be sufficiently matured to allow the realization of a fully electric regional aircraft within the next decade. Instead, an intermediate step will be required to significantly reduce GHG emissions already by 2035. The development of a hybrid-electric propulsion system for regional aircraft with at least 50% hybridization represents this very challenging, yet achievable intermediate step and can allow for a mission fuel burn reduction by at least 50% compared to 2020 state-of-the-art regional aircraft. A thermal engine that allows for usage of 100% sustainable aviation fuel, will allow to reduce lifecycle GHG emissions by 90% and thus close to zero. The proposed project AMBER (innovAtive deMonstrator for hyBrid-Electric Regional application) addresses this aspect and pursues the maturation of hybrid-electric key components and the validation of a product-representative parallel hybridelectric propulsion system architecture, fuel cell based, for next-generation regional aircraft with EIS by 2035 to meet the ambitious environmental goals set out in SRIA and the Clean Aviation topic call.
