[1] Size distributions (d > 15 nm) and volatile properties of combustion particles were measured during test‐rig experiments on a jet engine, consisting of a combustor and three simulated turbine stages (HES). The combustor was operated to simulate legacy (inlet temperature 300°C) and contemporary (500°C) cruise conditions, using kerosene with three different fuel sulfur contents (FSC; 50, 400 and 1300 μg g⁻¹). Measurements found that contemporary cruise conditions resulted in lower number emission indices (EI_N15) and higher geometric mean particle diameter (d_G) than for legacy conditions. Increasing FSC resulted in an overall increase in EI_N15 and decrease in d_G. The HES stages or fuel additive (APA101) had little influence on EI_N15 or d_G, however, this is uncertain due to the measurement variability. EI_N15 for non‐volatile particles was largely independent of all examined conditions.
