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。许多研究突出表明，迫切需要使全球工业脱碳，并大幅减少包括航空业在内的所有部门的污染物排放。尽管由于业务量大，航空对全球环境的影响主要由中小型市场飞机推动，但只有在规模较小或规模较小的新型使能技术逐步成熟之前，才能为这些应用所需的电力需求开发颠覆性技术。因此，区域航空的转型，即飞行距离为500至1000公里、最多可容纳100个座位的飞机，将引领实现可持续发展的道路，具有特别重要的意义。电池和液氢燃料电池技术还不够成熟，不足以在未来十年内实现全电动支线飞机。取而代之的是，需要采取中间步骤，在2035年之前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着这一极具挑战性但可实现的中间步骤，与2020年最先进的支线飞机相比，可以使任务的燃料消耗减少至少50%。允许使用100%可持续航空燃料的热力发动机将使生命周期温室气体排放量减少90%，从而接近于零。拟议的项目AMBER(混合动力电力区域应用创新示范)解决了这一问题，并致力于混合动力关键部件的成熟，以及到2035年验证具有产品代表性的基于燃料电池的并行混合电力推进系统架构，用于具有EIS的下一代支线飞机，以实现SRIA和清洁航空专题电话会议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.
