Title:
METHOD FOR DETERMINING AN EFFICIENCY FAULT OF AN AIRCRAFT TURBOSHAFT ENGINE MODULE
Document Type and Number:
WIPO Patent Application WO/2022/096354
Kind Code:
A1
Abstract:
The invention relates to a method for determining an efficiency fault (R11-R15) of at least one module (11-15) of a turboshaft engine (T) of an aircraft (A), the method for determining comprising: • A step of determining an estimated real mapping (CARE), • A step of determining real indicators (IRE) from the estimated real mapping (CARE), • A step of determining (E3) a plurality of simulated mappings from a simulation of a theoretical model of the turboshaft engine (T) for different efficiency configurations, • A step of determining (E4) simulated indicators (ISx) for each simulated mapping (CARSx), • A step of training (E5) a mathematical model (CLASS) by coupling the simulated indicators (ISx) with efficiency configurations (CR), and • A step of applying (E6) said mathematical model (CLASS) to the real indicators (IRE) so as to deduce therefrom a real efficiency configuration (CR).
