Abstract

Studies of the consequences of mistuning on bladed disc vibration levels have been undertaken for over 40 years and yet mistuning is still an unresolved problem for turbomachinery designers. Why is this? How have we failed to solve this problem? And what can we do now? This paper proposes a different approach which seeks to manage, rather than solve, the blade mistuning problem.
