Abstract The ingestion of airborne particulate into aircraft engines is an undesirable consequence their operation, particularly in and out arid locations that leads to reduced time between overhaul. Predicting the maintenance burden environments rich made difficult by large number parameters influence likelihood retention particles on nozzle guide vanes. In this contribution, we propose a new,...

The work is devoted to the search for new vacuum-plasma coatings with high hardness increase durability of compressor blades GTE aircraft engines Ti-Al-N-based obtained by Avinit technologies, which ensure application hard, high-quality dramatically reduced micro-arc damage, were selected as candidates. multilayer have higher functional characteristics than TiN (microhardness, crack resistance,...

The article examines the possibility of using converted aircraft engines for gas pumping units example main parts GTE - disks NK-8-2U engine and NK-16ST NK-16-18ST ground engines. For all second stage low-pressure turbines three engines, stress-strain state calculation was performed boundary integral equations method (BEM) FEM in Ansys program. disk stress concentrators, theoretical concentrati...
