Particle emission parameter analysis from multirole fighter aircraft engine

Abstract

The topic of emissions from combustion engines has gained a lot of interest in the scientific community and involved public opinion due to the known association between exposure to multiple air pollutants and short and long-term effects on human health. The growing knowledge of the processes involved in the creation of air pollution from combustion engines and a dynamic development of emission measuring devices lead to the creation of new rules and conditions for the certification of aircraft engines. The article presents an analysis of the size distribution of particles emitted from jet engine. Studies were performed in stationary conditions on an engine dynamometer. The aim of the study was to determine the size and mass distributions of particles emitted by jet engine in different operating parameters. The main subject of the analysis were total concentration and size distribution of particles. On the basis of those data, mass distributions of particles were calculated.
