SHOCK STRUT SERVICE MONITORING USING GAS PRESSURE AND TEMPERATURE SENSORS, COMBINED WITH PHYSICAL STRUT MEASUREMENT AND TAKING INTO ACCOUNT GAS ABSORPTION/DESORPTION IN A FLUID

摘要

A method for monitoring a shock strut may comprise measuring a first shockstrutpressure, measuring a first shock strut temperature, measuring a second shockstrut pressure,measuring a second shock strut temperature, measuring a shock strut stroke,and determining aservicing condition of the shock strut based upon the first shock strutpressure, the first shockstrut temperature, the second shock strut pressure, the second shock struttemperature, and theshock strut stroke and taking into account at least one of an absorption of agas with a fluid anddesorption of the gas with the fluid.In various embodiments, the method may further comprises measuring a thirdshock strutpressure, measuring a third shock strut temperature, wherein the servicingcondition is furtherbased upon the third shock strut pressure and the third shock struttemperature.
