Abstract:
1. A monitoring method comprising: calculating 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 further comprising the step of calculating a 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, wherein data coming in from the sensors are merged with data coming from reference models to validate a detection of a problem or breakdown, and wherein the reference models are a gulping model, a debris-generation model, a model for oil-tank level based on the content, a performance model for a pump, a pressure-difference model at the terminals of a filter, and a heat-generation model in the enclosure.
