System and method for monitoring an aircraft engine

摘要

An aircraft engine monitoring system, comprising: - an acquisition module (3) for acquiring current measurements of physical quantities, called input (ME) and physical output quantities (MS), relating to said aircraft engine (15), - a simulation module (5) of the physical behavior of said aircraft engine, to simulate values of output physical quantities (VS) as a function of said current measurements of input physical quantities (ME ), - a processor (9) for calculating physical margins, known as real (MR), between said simulated values of physical output quantities (VS) and said corresponding current measurements of physical output quantities (MS), - a module d 'learning (7) for predicting margins, called predicted margins (MP), from current measurements of input physical quantities (ME), and in that said processor (9) is configured to calculate monitoring residuals ( R) showing an indication of the condition of the aircraft engine .
