1. ) A method of partitioning turbomachine faults, comprising:
- using a modeling computer to model a system and to establish a modeled gas path parameter and a modeled subsystem parameter;
determining a gas path condition representing a difference between an actual gas path parameter and the modeled gas path parameter;
determining a subsystem condition representing a difference between an actual subsystem parameter and the modeled subsystem parameter; and
diagnosing a sensor failure based on the gas path condition and the subsystem condition.

Abstract
An example method of partitioning turbomachine faults includes using a modeling computer to model a system, to establish a modeled gas path parameter, and to establish a modeled subsystem parameter. The method then determines a gas path condition representing a difference between an actual gas path parameter and the modeled gas path parameter. The method also determines a subsystem condition representing a difference between an actual subsystem parameter and the modeled subsystem parameter. The method diagnoses a sensor failure based on the gas path condition and the subsystem condition.

9. ) A method of partitioning gas turbine engine faults, comprising:
-
establishing a model of a gas turbine engine; using the model to determine a modeled gas path parameter and a modeled subsystem parameter; and identifying a fault in the gas turbine engine based on a comparison of the modeled gas path parameter to a measurement of an actual gas path parameter of the gas turbine engine and a comparison of the modeled subsystem parameter to an actual subsystem parameter from the gas turbine engine. - View Dependent Claims (10, 11, 12, 13)
