Title: SYSTEM AND METHOD FOR MONITORING A TURBOMACHINE WITH ANOMALY DETECTION CORRECTED BY A WEAR FACTOR
Abstract:
The invention relates to a system (1) for monitoring the state of health of a monitored aircraft engine (2). The system comprises an anomaly detection unit (3) which analyses engine operating parameters and raises an alarm (Al) if a result of the analysis of one of the engine operating parameters crosses a threshold, the alarm being associated with a probability of a given type of engine damage occurring. The system (1) further comprises an engine operating conditions monitoring unit (4) which determines a state of wear of the engine, and an alarm corroboration unit (5) which weights the said probability of occurrence by the determined state of wear. The invention finds an application in the preventive maintenance of turbomachines.
