Helicopter Turboshaft Engine Emission Estimation Based on Standard Flight Profile

Over the past decades, environmental protection, including regulation of air pollution, has become an important economic and political issue. Although aviation accounts for only 2% of atmospheric pollution, regulation at national, international and global level is still very important. The high-level aim of our current research is to determine the emissions of aircraft engines in the defense sector and to explore ways to reduce them by using alternative fuels, focusing military aviation. This article presents the methodology for developing a standard flight profile, which is the basis for calculating the operational emissions of military helicopters.
