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 shock strut pressure, measuring a first shock strut temperature, measuring a second shock strut pressure, measuring a second shock strut temperature, measuring a shock strut stroke, and determining a servicing condition of the shock strut based upon the first shock strut pressure, the first shock strut temperature, the second shock strut pressure, the second shock strut temperature, and the shock strut stroke and taking into account at least one of an absorption of a gas with a fluid and desorption of the gas with the fluid.;In various embodiments, the method may further comprises measuring a third shock strut pressure, measuring a third shock strut temperature, wherein the servicing condition is further based upon the third shock strut pressure and the third shock strut temperature.
