The innovative aircraft jet engines are the most important power units of modern planes nowadays and therefore it is necessary to analyse their environmental impacts, with regard to quality of living environment. This paper integrates technical and environmental factors of up-to-date jet engines. It demonstrates an important fact that modern airplanes equipped by sophisticated turbo-jet engines are environment friendly with regard to reduced amount of pollutants in their exhaust gases. %K jet engine %K by-pass ratio %K gaseous emissions %K fuel consumption %U http://www.qip-journal.eu/index.php/QIP/article/download/46/33
