Abstract
The methods which have been used recently to predict the amplitudes of vibration of compressor blades are explained. Examples for resonances with maldistributions in the intake flow and downstream blockages are given. Two techniques of obtaining blade vibration data from the HP shaft of a two-shaft jet engine are described. By comparing the measured amplitudes with the fatigue properties of blading, a parameter has been established which is used in assessing the seriousness of a vibration when considering its service life.
