NSTU scientists have developed specialized software for accurate modeling of pollutant emissions from aircraft engines. The program is intended to substantiate sanitary protection zones around airports.
The development makes it possible to calculate the dispersion of impurities from moving sources taking into account all stages of the takeoff and landing cycle: taxiing (low thrust), takeoff (maximum power), climb, landing, and other phases. Each stage is characterized by its own composition and volume of emissions.
To work with the software, it is sufficient to upload an airport site plan, set aircraft movement trajectories, and perform a calculation of the full \"takeoff — landing\" cycle. The results are visualized by concentration isolines of harmful substances. The methodology is based on a system of gas-dynamic equations describing the transport and diffusion of impurities taking into account local meteorological conditions, the geometry of taxiways, runway slopes, aircraft types, and flight intensity.
The use of modern methods significantly improves the accuracy of calculations compared with traditional methods and makes it possible to establish environmental load standards from airports on a more substantiated basis.
