An analysis of oil sample data obtained from aircraft engines by spectrometry
Abstract
The spectrometric oil analysis program as applied to naval
aviation was developed as a portion of the overall aviation safety
program of the U. S. Navy. The equipment and techniques have been
refined, and the program has been steadily expanded since its
inception in 1955. The value of this system in determining densities
of microscopic particles of certain oil-wetted wear metals
in samples of oil extracted from aircraft engines has proved to be
helpful in predicting incipient engine failure. In this study
data relating to both reciprocating and jet engine models was analyzed
in an attempt to determine which of the following elements
provided significant information regarding the internal condition
of the engine: aluminum, iron, chromium, silver, magnesium,
nickel, copper, and silicon.
Multiple and simple linear regression analyses and correlation
techniques were applied in order to determine the mathematical
model which corresponded most closely to the data compiled.
