FIELD: engines and pumps.
SUBSTANCE: signal E10 typical of rotor vibration level in turbojet operation is received to define rotor rotation mode E20 during operation. Signal amplitude E40 is compared with at least one predetermined vibration threshold depending upon rotor rotation mode. In case amplitude peak exceeds said threshold signal E50 in strobe pulse formed around amplitude peak to define (E60) is phenomenon caused said amplitude peak is either a mechanical impact at turbojet rotor or a signal electronic disturbance.
EFFECT: reliable detection of faults.
