METHOD FOR MONITORING THE OIL SYSTEM OF A TURBOMACHINE
First Claim
1. An overall monitoring method allowing to calculate the autonomy of a lubrication system of an airplane engine and further allowing the diagnosis and prognosis of a plurality of problems and breakdowns of the engine and of its lubrication system by means of measurements taken by sensors arranged in said lubrication system, the method comprising the step of calculating the status of the lubrication system at a given moment and calculating its evolution over time in order to determine the remaining lifetime before a breakdown.
