Vibration of turbine engines with criterion for qualitative rotor collection and their technical condition

Abstract

This article discusses the problem of vibration of aircraft turbine engines, given the imbalance of the rotor stages. It is shown that the amount of information contained in the data obtained by constant measurements of the amplitudes and frequencies of the transverse vibration of the motors, especially in the case of a multirotor, cannot be excessive. The interconnections of these parameters with the structural form of the rotors, the quality of their implementation and assembly, the effect on the gaps in the bearings and the capabilities of detecting emergency engine conditions are presented.
