Systematic spectral monitoring method for e.g. jet engine of Boeing 737, has performing systematic statistical search of correlation between functional abnormality and frequential spectrum abnormality of any periodic phenomenon
The method involves performing systematic statistical search of a correlation between functional abnormality and frequential spectrum abnormality of any periodic phenomenon in real time. An extension is performed to mode spectrums. Vibrations of a medium and vibrations of an engine are analyzed using microphones and accelerometers. Health of the engine is judged in a permanent manner, and an alarm is activated if necessary. Preventive maintenance operations are triggered according to need.
