Abstract:
A method for the detection of failure in a turbomachine by monitoring the performance of the turbomachine is provided. The method includes measuring at least one performance parameter of the turbomachine in order to obtain an actual signature for the performance of the turbomachine; comparing the actual signature of the turbomachine with a database of failures associating reference signatures for the performance of the turbomachine with identifiers of failure, the database of failures being obtained by the simulation of failures on the basis of a theoretical model of the thermodynamic cycle of the turbomachine; and determining the identifier of failure of the turbomachine for the actual signature.
