摘要： A degradation state of the gas turbine is repeatedly estimated with the aid of a set of measured values, at least one of the measured values not being taken into account in each case during the estimation. A deviating estimate which deviates substantially from the remaining estimates or from an estimate which takes account of all the measured values implies that a measured value which has not been taken into account for this deviating estimate is defective. This renders it possible to distinguish in a simple way between changes in state and measuring errors. In the case of a method for determining a degradation of a gas turbine which is being implemented in any case, the determination of defective sensors according to the invention is possible with a low programming outlay and without assumptions concerning a response of individual sensors.

摘要： A system and method for determining performance of an engine is provided. The system includes two or more sensors configured in operable arrangement at two or more respective positions at a flowpath. The system includes one or more computing devices configured to perform operations, the operations include acquiring, via the two or more sensors, parameter sets each corresponding to two or more engine conditions different from one another, wherein each parameter set indicates a health condition at a respective location at the engine; comparing, via the computing device, the parameter sets to determine the respective health condition corresponding to the respective location at the engine; and generating, via the computing device, a health condition prediction based on the compared parameter sets.
