The Evaluation of the Fotoscope as a Supplement to SOAP.
Abstract
Spectrometric oil analysis is the primary laboratory technique used by the Air Force to determine oil condition in aircraft engines. The Fotoscope is an instrument that is used by some airlines to supplement the more extensive laboratory procedures. Used oil samples were analyzed with the Fotoscope and compared with their respective spectrometric analysis results to determine if the Fotoscope could be used to supplement the Spectrometric Oil Analysis Program (SOAP). Graphs were plotted and correlation coefficients were calculated to determine relationships between Fotoscope values and wear metal concentrations of oil samples. Additional tests were conducted to determine the effects of various parameters on Fotoscope readings. Fotoscope threshold values were chosen for each engine based on critical wear metal limits. Although a true relationship between the Fotoscope and spectrometric results was not apparent, threshold depictions revealed that the instrument could be used to supplement SOAP if warranted by further investigation.
