Abstract

This paper shows a compressor of aircraft engine AE-20 as an example how with the help of mathematical model of vibrations of multi staged compressor rotor on elastic supports connected to the masses of frames of crankcase and combustion chamber and amplitudefrequency characteristics of all the system being recorded during the time of rotor rotation it is possible to identify unknown parameters of the system and to calculate origins of all resonances.
