PROBLEM TO BE SOLVED: To detect the state of part deterioration without requiring an overhauled inspection.;SOLUTION: Data on turbine gas temperature, variation in the turbine gas temperature with elapse of time, and the state of deterioration of parts to be predicted for deterioration is collected based on the accelerated durability test of a gas turbine engine on an engine bench, operation data obtained so far, and engine overhauled inspection data obtained so far. Based on the collected data, gas turbine temperature-time index values on the deterioration of the parts are obtained (step 1: S1). Next, the variation in turbine gas temperature with elapse of time of an actually operated gas turbine engine is monitored (step 2: S2). The integrated value of the turbine gas temperature-time index values is obtained according to the variation in turbine gas temperature with elapse of time (step 3: S3). Then, on the basis of the integrated value, the state of deterioration of the parts of the actually operated gas turbine engine is predicted (step 4: S4).;COPYRIGHT: (C)2004,JPO
