Software Developed in Russia to Model Aircraft Emissions
The tool can be used to assess pollution levels when calculating sanitary buffer zones around airports.
Researchers at Novosibirsk State Technical University NETI have developed software to model pollutant emissions from aircraft, the university’s press service said.
According to Anna Turchinovich, associate professor in the Department of Environmental Engineering at NSTU NETI and a candidate of technical sciences, the team created a program to calculate how pollutants disperse from aircraft at different stages of takeoff and landing. Each stage produces a different composition and volume of emissions. The environmental footprint of every airport is also unique, depending on flight intensity, aircraft types, and infrastructure.
The software allows users to upload an airport map, map an aircraft’s trajectory, and calculate emissions, visualizing concentration levels through contour lines. The methodology is based on a system of gas-dynamic equations that describe how impurities spread, taking into account diffusion and transport processes.
Each Stage Has Its Own Characteristics
A second area of research focuses on assessing the level and pattern of pollutant dispersion, factoring in chemical reactivity and interaction with a blast deflector — a device that redirects and disperses powerful air streams.
The calculations can be used when designing sanitary protection zones around airports. These boundaries are established to shield residential areas from the negative impact of airport operations.
