Abstract
The article presents the results of particles measurements from a jet engine. Engine parameters were analysed during the actual flight and an attempt was made to map it in stationary tests. Research results were supported by correlation analysis. Based on measurements of particulate matter it was found that the most favourable conditions for particle formation occur during taxiing. Mass distributions were presented and emission factors were determined for three basic phases: taxiing, take-off and approach. The applied research methodology was based on the latest guidelines and was expanded to include propositions related to the analysis of engine operation in real flight conditions.
Highlights
Particles emitted by aircraft engines adversely affect human health and contribute to deterioration of air quality
Engine parameters obtained during the flight and in stationary tests were subjected to correlation analysis
The presented test results indicate that during taxiing operation from one kilogram of fuel the biggest mass of particulate matter is produced. This is extremely disadvantageous from the point of view of air pollution, because the emission takes place on the ground, the dispersion of particulate matter is more difficult in comparison to the other air operations
Summary
Particles emitted by aircraft engines adversely affect human health and contribute to deterioration of air quality. Particles with a diameter of 10 μm or less can cause various diseases and related deaths. The severity of diseases is combined with the long-term effects of particles in the environment. They contribute to the occurrence of diseases such as asthma and bronchitis. They are one of the causes of cardiac arrhythmia and heart attacks. The lowest resistance to the negative effect of particles is demonstrated by people with heart and lung diseases, the elderly and children [1, 2]. The diameters of the discussed particles reach values of several dozen nanometers
