Building a sustainable and climate neutral future for aviation is an inevitable requirement for a society with increasing mobility needs. If we are to stabilise the global temperature below the 1.5°C threshold set by the Paris Agreement, rapid action is to be taken. MINIMAL will contribute to a radical transformation in air transport by providing disruptive ultra-efficient and low-emission technologies that will, in combination with the aviation ecosystem, sustainably reduce the climate impact of aviation. The MINIMAL project will, through an unprecedented effort between European engine OEMs, world leading atmospheric physics scientists, and lead researchers in combustion and propulsion, attack the major sources of non-CO2 and CO2 emissions in aeroengines. This will be accomplished with the introduction of climate optimised new propulsion systems based on composite cycle engine technology, that provides unparalleled flexibility with respect to operations, and that has the potential to eliminate the large sources of effective radiative forcing by 2035: 80% reduction from contrails, 52% reduction from net-NOx, and 36% fuel burn reduction resulting in 36% to 100% CO2 reduction, depending on the fuel used. Results will allow assessing the interdependencies between non-CO2 and CO2 effects already during the early stages of aero-thermal-mechanical design and converge into engine options that have minimum climate impact. The findings are supported by numerical (TRL 2) and experimental (TRL 3) proof of concept of Low-NOx opposed-piston constant volume combustion technology with pre-micromixing of hydrogen. In MINIMAL we understand the urgency and aim for maximum impact. Aggressive, but realistic roadmaps will be outlined together with regular exchanges in major industry research centres to develop these technologies into products and bring them to in 2035-2040.

对于交通需求日益增加的社会来说，建设可持续的、气候中和的未来是必然的要求。如果我们要将全球气温稳定在《巴黎协定》规定的 1.5°C 阈值以下，就必须采取最少的行动。通过提供超高效和低排放技术，与航空生态系统相结合，可持续减少航空对气候的影响，通过欧洲发动机原始设备制造商的前所未有的努力，为航空运输的彻底变革做出贡献。世界领先的大气物理学科学家以及燃烧和推进方面的主要研究人员致力于解决航空发动机中非二氧化碳和二氧化碳排放的主要来源，这将通过引入基于复合循环发动机技术的气候优化新型推进系统来实现，该系统提供了无与伦比的性能。操作方面的灵活性，并有可能到 2035 年消除有效辐射强迫的大型来源：凝结尾迹减少 80%，净氮氧化物减少 52%，以及燃油消耗减少 36%，二氧化碳减少 36% 至 100%，具体取决于所使用的燃料。结果将允许在气动热机械设计的早期阶段评估非二氧化碳和二氧化碳效应之间的相互依赖性，并融入发动机。对气候影响最小的选项得到了低氮氧化物预微混合的对置活塞定容燃烧技术的数值 (TRL 2) 和实验 (TRL 3) 概念验证的支持。在 MINIMAL 中，我们了解实现最大影响的紧迫性和目标，并将与主要行业研究中心的定期交流一起制定积极而现实的路线图，以将这些技术开发成产品并在 2035 年至 2040 年实现。
