Improving Local Air Quality at airports while at the same time decarbonising aviation can be achieved by switching to sustainableaviation fuels (SAFs) and hydrogen (H2), as confirmed by recent engine development programs. However, both these fuels requiresignificant developments in the gas-turbine combustor because present technologies not only to further reduce NOx and PM emissionsas expected by long-term standards and objectives but also are not normally suitable for 100% direct combustion of hydrogen. In thisproject, revolutionary combustor architectures will be studied, extending the preliminary results of previous Clean Sky 2 "Innovative NOxReduction Technologies" projects in terms of scientific scope and TRL. In particular, this project will advance (i) the Lean AzimuthalFlame (LEAFinnox), a novel combustion system based on Flameless Oxidation, (ii) the Compact Helically Arranged combustoR(CHAIRlift), a new system which uses interacting lean lifted flames, and (iii) plasma and electric manipulation of the spray and of theflame stabilisation mechanism. The fuel flexibility offered by these novel concepts is key to allow for SAF and H2 operations. Thisunique feature will be exploited to give novel dual-fuel LTO cycle strategies and ultra-low NOx, ultra-low soot single or dual-fuel use.Experiments on available dedicated rigs and numerical work will be performed to provide knowledge at the fundamental and practicallevel that will allow TRL3 and higher developments at the end of the project. The project will include new CFD, low-order, and AImodels, and novel stabilisation techniques ripe for commercial exploitation.

最近的发动机开发计划证实，可以通过改用可持续的航空燃料(SAF)和氢气(H2)来改善机场的本地空气质量，同时实现航空脱碳。然而，这两种燃料都需要在燃气轮机燃烧室中进行重大开发，因为目前的技术不仅可以进一步减少氮氧化物和颗粒物的排放，而且按照长期标准和目标的预期，还不适合氢气的100%直接燃烧。在这个项目中，将研究革命性的燃烧室架构，在科学范围和TRL方面扩展先前Clean Sky 2“创新NOx还原技术”项目的初步成果。特别是，该项目将推进(I)基于无焰氧化的新型燃烧系统--稀薄方位火焰(LEAFInnox)，(Ii)紧凑型螺旋布置燃烧室(座椅升降机)，一种使用相互作用的稀疏提升火焰的新系统，以及(Iii)喷雾和火焰稳定机制的等离子和电子操纵。这些新概念提供的燃料灵活性是允许SAF和H2操作的关键。将利用这一独特的功能，提供新颖的双燃料低氧循环策略和超低NOx、超低碳烟的单燃料或双燃料使用。将在现有专用钻机上进行实验和数值工作，以提供基础和实践层面的知识，以便在项目结束时进行TRL3和更高级别的开发。该项目将包括新的CFD、低阶和人工智能模型，以及成熟的商业开发的新稳定技术。
