AIRCRAFT GAS TURBINE ROTOR BLADES VIBRATION

Abstract

Reliable running of the aircraft blade engine is often endangered due to various factors that inseparably affect it during the motor running. One of the endangering factors is also the oscillation of engine rotor blades which can lead, under certain circumstances, to the resonance of blades. There can occur the gradual increase of the amplitude of oscillation, creation of cracks and consequential destruction of the component part. For this reason, attention has been focused on the problems of rotor blades oscillations.
