System for detecting the first signs of a malfunction of an aircraft engine valve
First Claim
1. A system for detecting the first signs of a malfunction of an aircraft engine valve, comprising:
- an acquisition device to acquire the output pressure measurements of said valve, and contextual and command data of said valve,a processor configured to define a set of indicators of the first signs of malfunction, according to said output pressure measurements and said contextual and command data, wherein said processor is further configured to determine a set of estimators corresponding to said set of indicators of the first signs of a malfunction, using a previously produced regression model,said processor being further configured to compute at least one distance between said set of indicators and said set of estimators, andsaid processor being further configured to compare said at least one distance to at least one threshold of the first signs of a malfunction, in order to detect the first signs of malfunction of the said valve.

Abstract
A method and a system for detecting the first signs of malfunction of an aircraft engine valve, including an acquisition device to acquire the output pressure measurements of the valve, and contextual and command data of the valve, a processor to define a set of indicators of the first signs of malfunction, according to the output pressure measurements and the contextual and command data. A set of estimators corresponding to the set of indicators of the first signs of a malfunction, is determined using a previously produced regression model. At least one distance between the set of indicators and the set of estimators is computed. The distance is compared to a threshold of the first signs of a malfunction, in order to detect the first signs of malfunction of the said valve.
