Synopsis:

The growing complexity of aircraft has increased the need of efficient diagnostic methods knowledge for safety and current maintenance. Fault diagnostics is teached as intersection of more discipline of science. Students education is focused on methods of machine gearbox, bearing condition monitoring and fault detection, nondestructive testing and digital circuits testing.
