Abstract :
The problem of early surge diagnostics of gas-turbine engine is considered. An approach on the base of modificated S-discriminant´s algorithm and wavelet analysis is developed to solve this task. Comparison of the received results and the surge detecting signals, incoming from DOL sensor is given.
