The impact of air dust on accelerated degradation and reliability of aircraft engines

<ns3:p>Reduced purity of the intake air has a direct impact on the processes of accelerated wear and tear of critical engine elements, its reliability and the safety of performing the aviation mission. The topics discussed were illustrated with examples, including the impact of volcanic dust and sand on the erosion of fan, compressor and turbine blades, and the impact of gasodynamic tract contamination on the performance of selected parameters of a turbofan engine. The article performs an analysis of aviation regulations and aircraft operating instructions, as well as design solutions for counteracting potential hazards related to the negative impact of dust. The operational experience of various aircraft users was reviewed and the results of endoscopic inspections of helicopter turbine engines were used as part of own research.</ns3:p>
