Abstract (en)
[origin: WO2020217004A1] A system for monitoring an aircraft engine, comprising: an acquisition module (3) for acquiring current measurements of physical size, referred to as input (ME) and output (MS) physical sizes, relative to the aircraft engine (15), a module (5) for simulating the physical behavior of the aircraft engine, in order to simulate output physical sizes (VS) as a function of the current measurements of input physical sizes (ME), a processor for calculating physical margins, referred to as actual physical margins (MR), between the simulated values of output physical sizes (VS) and the corresponding current measurements of output physical sizes (MS), a learning module (7) for predicting margins, said margins (MP) being predicted using current measurements of input physical sizes (ME) and in that the processor (9) is configured to calculate surveillance residuals (R) showing an indication of the status of the aircraft engine.
