Abstract: A method for recognizing an anomaly in measured operating values of a turbomachine, in particular an aircraft turbine, including repeatedly detecting measured operating values of particular operating parameters of a turbomachine uring an operating period of the turbomachine, using sensors of the turbomachine, ascertaining quasi-steady-state time intervals of the operating period, using an analysis device, generating quasi-steady-state operating data points for the quasi-steady-state time intervals, the quasi-steady-state operating data points including averaged measured operating values, ascertaining particular expected data points which include particular expected operating values of the particular operating parameters, ascertaining particular measured operating value residuals of the particular operating parameters, checking the measured operating value residuals of the particular quasi-steady-state operating data points for compliance with predetermined anomaly criteria with regard to predefined nominal va

Abstract: A fast response temperature probe which may be used for a method for measuring an instantaneous temperature of a periodically changing fluid flow within a gas turbine is proposed. The temperature probe includes a substrate and a resistive element arranged at a surface of the substrate. Therein, at least at a surface of the substrate contacting the resistive element, the substrate comprises an insulating material having a thermal product of less than 1.5 kJ/(m2K sqrt(s)). The substrate or at least its surface is made from polyamide-imide such as for example fiber-reinforced Torlon© 5030. The temperature probe may allow measurements of instantaneous local temperatures of very fast fluctuations of more than 50 kHz at high spatial resolutions of, e.g., less than 0.5 mm2. The instantaneous temperature of a periodically changing fluid flow may be determined by correlating first and second sets of temperature measurements taking into account the periodicity of the periodically changing fluid flow.

Abstract: A device and method for monitoring a gas turbine is disclosed. The device includes a receiver for receiving condition values of the gas turbine and an analytical device. The analytical device is designed to determine condition information from the condition values of the gas turbine using Bayes' Prediction.
