https://www.theses.fr/2022ULILR019« Impact de la composition du carburant sur les émissions aéronautiques, une approche multi-échelles » Impact of fuel composition on aeronautical emissions, a multi-scale approachPhLAM Laboratory / DMPE ONERASpecialized in the measurement of non-volatile particles (measurement of mass concentration, number concentration and particle size distribution according to SAE recommendations) as well as in the chemical characterization of particles and gas phase emissions from aeronautical fuel combustion by Mass Spectrometry. This work concerns the characterization of the emissions of a laboratory burner, mini-CAST "liquid", and of combustion benches (ONERA installation) carrying out the combustion of standard and alternative fuels. A part of the work is also devoted to the characterization of a helicopter engine. The objective of this work is to relate the chemical composition of the emissions and the characteristics of the nvPM with the composition of the fuel (standard Jet A-1, SAF, blend between the two), the power and the configuration of the engine. - Experimental campaign in laboratory (ONERA ; JetScreen), on test benches (ONERA ; JetScreen, Soprano) and on industrial site (SHE ; Antares)- Mastery of measurement instruments and methodologies- Data analysis and presentation at national and international conferences- Study of international regulations and standards on aeronautical emissions- Internship supervisor (4 months)
