Estimation Method of Pollutant Emissions in Certain Aircraft Flight

Abstract

This paper intends to calculate the emissions of pollutants during the route flight quantitatively. In this paper, the flight dynamics model of the climb, cruise and descent phases are established respectively. Then, the pollutant emission estimation model of the aircraft is established based on the ICAO LTO model and the benchmark emissions data of engine manufacturers. Take certain civil aviation aircraft into account, a typical route is simulated, then the emissions of various pollutants at different flight stages are calculated and analyzed. Finally, several typical cruise strategies are selected for further comparative analysis. The results show that CO2 and NOX are the main pollutants during route flight. In addition, the pollutant emissions during the cruise phase are the highest, and the pollutant emissions during route flight can be effectively reduced by choosing the appropriate cruise strategy. The research results can be used to quantify and analyze the impact of flight performance optimization on civil aviation energy conservation and emission reduction, so as to better satisfy the requirements of green operations while ensuring flight safety.
