Patent ID: 8903692

Claim:
A method for the detection of failure for a turbomachine by monitoring the performance of the turbomachine, comprising: measuring at least one parameter for the performance of the turbomachine; obtaining an actual signature for the performance of the turbomachine based on the measured at least one parameter; obtaining a database of failures associating reference signatures for the performance of the turbomachine with identifiers of failure by simulating failures based on a theoretical model of a thermodynamic model of the turbomachine; comparing the actual signature of the turbomachine with the database of failures; determining the identifier of failure of the turbomachine for the actual signature, wherein the obtaining the database of failures comprises: parameterizing the theoretical model by modifying a definition of a component part of the turbomachine in the theoretical model such that the turbomachine simulates a failure of said component part, the simulated failure being identified by its identifier of failure; calculating thermodynamic quantities obtained from the thermodynamic cycle of the turbomachine defined by the theoretical model as parameterized; calculating a reference signature for the said turbomachine on the basis of the thermodynamic quantities; and associating the calculated reference signature with the identifier of failure in the database of failures.
