METHOD AND SYSTEM FOR MONITORING THE PERFORMANCE OF A HYDRAULIC SYSTEM OF AN AIRCRAFT

원문 (중국어)

A method for monitoring performance of a hydraulic system of an aircraft includes collecting values of temperature of a hydraulic fluid of the hydraulic system, measured by a sensor during a flight of rank i of the aircraft, determining the value of maximum temperature of rank i, denoted T, from amongst the values collected, calculating at least one temperature variation indicator being a function of T, if this temperature variation indicator is greater than a first threshold, calculating a temperature increase indicator, denoted α, being a function of a comparison between Tand a reference value β, and triggering an alert if αis greater than a second threshold. It is possible to carry out a monitoring of the performance of this hydraulic system in a simple, reliable manner and allowing potential interruptions in operation to be anticipated by raising maintenance alerts sufficiently early.
