Abstract The formation and development of atmospheric aerosols as a result of subsonic aircraft emissions are considered. The sequence of hydrodynamic and physicochemical processes in the combustion chamber, the engine duct, the jet, and the external atmosphere, leading to heterogeneous and homogeneous condensation and the formation of dispersed phases of various composition in the upper troposphere and lower stratosphere, is analyzed. The latest data are used to predict the amount of aircraft aerosol at these altitudes, which by the beginning of the next century may be comparable with traditional geological, anthropogenic and atmospheric factors. Attention is drawn to the fundamental effect — the formation of sulfur aerosols in the exhaust jet. Approximate models in which the important part played by binary condensation of a water-sulfuric acid mixture with the formation of fine droplets of sulfuric acid are proposed.
