<p>An electrical input signal representative of the existing operating state of a rotating bladed disk is classified into one of a plurality of predetermined operating states and a sequence detector is employed for detecting the occurrence of one of a plurality of possible predetermined sequences of such operating states. Predetermined fixed damage coefficients are then correlated with respectively corresponding detected predetermined sequences of operating states and accumulated with other similarly selected damage coefficients so as to provide a cumulative indication of low cycle fatigue damage done to the rotating bladed disk over its past history of experienced operating state sequences.</p> |
