In-light of recent research and publicity, directly linking increased mortality rates with soot emissions from the transport sector including aviation gas turbines - international regulators, through the ICAO, have recently set a new international non-volatile Particulate Matter (nvPM) standard for civil aviation Gas Turbine Engines. Towards understanding the likely impact of widespread adoption of Sustainable Aviation Fuel (SAF) on local air quality, this experimentally based collaborative (Engineering & Chemistry) project will determine the mechanisms by which soot (non-volatile and volatile PM) are formed within high pressure combustion systems. Conventional, drop-in and Sustainable Aviation Fuels will be characterised in terms of their physical and chemical properties, using the novel application of fuel and soot analysis techniques (e.g. NMR, XPS-Sp2) to assess the soot formation mechanism. This assessment will provide confidence that 'fuels of the future' offer a lower impact to the local air quality surrounding airports in terms of both regulated (nvPM) and currently unregulated volatile Particulate Matter (vPM), hence ensuring an improvement in health for the local demographic along with the perceived benefits of Carbon reduction. Using the knowledge gained in achieving the above aims a second angle of this project will be understanding how laboratory scale combustors maybe used to create soot with similar morphology to real-life aircraft emissions - with the aim of generating aerosols suitable for in-vitro health study and calibration of regulatory nvPM analysers.

根据最近的研究和宣传，将死亡率的增加与包括航空燃气涡轮机在内的运输部门的烟尘排放直接联系起来--国际监管机构最近通过国际民航组织为民用航空燃气涡轮机发动机制定了新的国际非挥发性颗粒物（nvPM）标准。为了了解广泛采用可持续航空燃料（SAF）对当地空气质量的可能影响，这个基于实验的合作（工程与化学）项目将确定高压燃烧系统内形成烟尘（非挥发性和挥发性PM）的机制。传统的、直接使用的和可持续的航空燃料将根据其物理和化学性质进行表征，使用燃料和烟尘分析技术（例如NMR、XPS-Sp2）的新应用来评估烟尘形成机制。该评估将提供信心，即“未来燃料”在受管制（nvPM）和目前未受管制的挥发性颗粒物（vPM）方面对机场周围的当地空气质量的影响较低，从而确保改善当地人口沿着碳减排的感知效益。利用在实现上述目标中获得的知识，该项目的第二个角度将是了解如何使用实验室规模的燃烧器来产生与现实生活中的飞机排放物具有相似形态的烟尘-目的是产生适合于体外健康研究和监管nvPM分析仪校准的气溶胶。
