Stress state analysis of compressor blade-disk joint with the influence of centrifugal forces and blade mistuning

The authors present the results of the numerical experiments on the determination of the effect of compressor blade mistuning on the stress state of a blade-disk joint under the action of the centrifugal forces and their comparison with results of full-scale experiments. The analysis of the results...
