Abstract

Abstract

The experiment of high speed dynamic balance was done after power turbine rotor balance is destroyed.The vibration of the whole engine on test rig was measured and analyzed before and after the high speed dynamic balance of the power turbine rotor was conducted.The results show that the whole engine vibration is significantly reduced.High speed dynamic balance technique of flexible rotor plays an important role in reducing vibration of the turboshaft engine.
