SERVICING MONITORING SYSTEM FOR MIXED FLUID-GAS SHOCK STRUTS

摘要

A method and system of monitoring condition of a shock strut (12) senses gas temperature, gas pressure, and stroke of the strut (12) during a landing event. Oil loss is determined based upon a deviation of a transient pressure coefficient derived from transient gas pressures at two different strokes from a nominal coefficient value. Gas loss is determined based upon a temperature adjusted transient gas pressure at a selected stroke and a nominal gas pressure value at the selected stroke.
