Abstract

In this paper, several statistical methods are evaluated with respect to their applicability for the probabilistic analysis of a coupled flow-thermo-mechanical model of a low pressure turbine rotor. The probabilistic analysis is comprised of a sensitivity analysis followed by an uncertainty analysis. The sensitivity analysis is performed to gain a better understanding of the coupled flow-thermo-mechanical system. The uncertainty analysis, using probability distributions derived from the manufacturing process, allows the effect of the input uncertainties on the life duration of the rotor to be predicted.
