Alternative sustainable fuels, such as hydrogen, ammonia, bio/synthetic fuels produced from sustainable pathways, have been highlighted in recent policy whitepapers as a route to address the problems in decarbonising the aviation sector and to help deliver net-zero. The recent Jet Zero Strategy has highlighted the investment to accelerate the production and infrastructure of sustainable aviation fuels (SAF), and R&D priorities in delivering Zero-emission flight. For the likes of ammonia, hydrogen and other synthetic or low carbon aviation fuels, that behave very differently to conventional kerosene-type fuels, this will entail the development of new engine technologies tailored to the new fuels, either pure component or blended. While the fundamental combustion behaviour in terms of chemical kinetic reaction mechanism may be understood for many of these fuels in isolation, at elevated pressure this is less certain, and major challenges remain concerning flame stability.FLAME project focuses on net-zero propulsion, evaluating the fuels' impact on gas turbine performance and operability. Novel optical diagnostics and models will be developed that will enable the understanding of flame quenching and the lean blow-off (LBO) limits of new bio/synthetic-derived zero/low-carbon fuels, enhancing their application in gas turbine combustors.

最近的政策白皮书强调了替代性可持续燃料，例如通过可持续途径生产的氢、氨、生物/合成燃料，作为解决航空业脱碳问题和帮助实现净零排放的途径。最近的零排放战略强调了对加速可持续航空燃料（SAF）生产和基础设施的投资，以及实现零排放飞行的研发优先事项。对于氨、氢和其他合成或低碳航空燃料等，其性能与传统煤油型燃料非常不同，这将需要开发适合新燃料的新发动机技术，无论是纯组分燃料还是混合燃料。虽然许多这些燃料在化学动力学反应机制方面的基本燃烧行为可以被单独理解，但在高压下，这一点不太确定，而且火焰稳定性方面仍然存在重大挑战。FLAME 项目专注于净零推进，评估燃料对燃气轮机性能和可操作性的影响。将开发新型光学诊断和模型，使人们能够了解新型生物/合成衍生的零/低碳燃料的火焰淬火和稀薄吹气（LBO）限制，从而增强其在燃气轮机燃烧室中的应用。
