Modern aircraft engines emit a complex mixture of gaseous and particulate material. While some ofthis particulate material is a primary emission, there are a species of particulate matter which formsdownwind of the engine, known as volatile particulate matter (vPM). The goal of this PhD is tobetter characterise the source and formation of vPM and their potential impact on the environment.The research involves working closely with Rolls-Royce to develop vPM measurement andsampling methods, obtain datasets from aircraft gas turbine combustion and analysis of existingdatasets from previous international measurement campaigns.With a nonvolatile particulate matter standard set to be implemented on aircraft engines in 2020,characterising vPM will be needed to inform regulators on a possible future vPM internationalaviation standard. A robust sampling and measurement methodology will need to be developed ifsuch a standard is implemented. There are several key knowledge gaps which need to beaddressed if the aerospace industry is to reduce vPM to below an applied standard. For example,there is a paucity of information regarding the influence of both fuel types and lubrication oils to thequantity of vPM emitted. The planned projects going forward include research conducted at bothRolls Royce facilities at Derby & Port Talbot, researching fuel & lubrication oil influences on ahelicopter GNOME engine & the influence of alternate fuels respectively. Research conducted inthe 2nd year of this project will be conducted at a Rolls Royce international facility, which will beconducted on only the cumbustor component of an aircraft engine. This will ensure that the vPMresults are entirely without influence from lubrication oils, providing a valuable comparison of theeffects of fuel types & lubrication oils on vPM.

现代飞机发动机排放一种气体和颗粒物质的复杂混合物。虽然其中一些颗粒物是一次排放，但也有一种颗粒物形成发动机的下风，称为挥发性颗粒物(VPM)。该博士学位的目标是更好地描述VPM的来源和形成及其对环境的潜在影响。研究涉及与罗尔斯-罗伊斯密切合作，开发VPM测量和采样方法，从飞机燃气轮机燃烧获得数据集，并从以前的国际测量活动中分析现有数据集。随着2020年在飞机发动机上实施非挥发性颗粒物标准，需要对VPM进行表征，以向监管机构通报未来可能的VPM国际航空标准。如果实施这样的标准，将需要制定一种可靠的抽样和测量方法。如果航空航天工业要将VPM降低到应用标准以下，有几个关键的知识差距需要解决。例如，关于燃料类型和润滑油对VPM排放量的影响的信息很少。未来计划的项目包括在德比和塔尔博特港的劳斯莱斯工厂进行的研究，分别研究燃料和润滑油对直升机侏儒发动机的影响以及替代燃料的影响。该项目第二年进行的研究将在劳斯莱斯国际设施进行，该设施将只对飞机发动机的减速箱部件进行测试。这将确保vPM结果完全不受润滑油的影响，为燃料类型和润滑油对vpm的影响提供了有价值的比较。
