Abstract


Diagnostic model for gas turbine elements based on wavelet spectral analysis method of vibration signals and S-discriminant is proposed in the work. The developed model could be used in construction of perspective control systems of aircraft engine units to analyze non-stationary signals and to give a diagnosis of engine units state.

Keywords


model of diagnostics, vibrations, wavelet filtering, S-discriminant, gas turbine engine units.
