Abstract:

The feasibility of using a X-ray fluorescence wear metal monitor to continuously monitor iron concentration levels in the lubrication system of an operating gas turbine engine was demonstrated. The X-ray wear metal monitor maintained oil seal integrity under the temperature and pressure environment of both laboratory simulated and actual engine operating conditions. The monitor also demonstrated the ability to make significant measurements of the iron concentration level in flowing MIL-L-7808 oil, under both laboratory and engine conditions, within a standard deviation of plus or minus three parts per million. This sensitivity is consistent with experience from the Spectrometric Oil Analysis Program.
