    Abstract

    The particles emitted from an aircraft engine combustor were investigated in the European project PartEmis. Measured aerosol properties were mass and number concentration, size distribution, mixing state, thermal stability of internally mixed particles, hygroscopicity, and cloud condensation nuclei (CCN) activation potential. The combustor operation conditions corresponded to modern and older engine gas path temperatures at cruise altitude, with fuel sulphur contents (FSC) of 50, 410, and 1270 œg g-1. Operation conditions and FSC showed only a weak influence on the microphysical aerosol properties, except for hygroscopic and CCN properties. Particles of size D = 30 nm were almost entirely internally mixed. Particles of sizes D <20 nm showed a considerable volume fraction of compounds that volatilise at 390 K (10-15%) and 573 K (4 - 10%), while respective fractions decreased to
