Abstract
A method for determining the remaining service life of a rotor of a thermally loaded turboengine in which a temperature on the rotor is determined. Thermal stress on the rotor is calculated from the determined temperature, and the remaining service life of the rotor is calculated from the derived thermal stress. The temperature is measured directly at a predetermined point of the rotor, and the thermal stress on the rotor is derived from the measured temperature.
