Abstract

The paper considers the deposition of metallic particles on the main oil filter of aircraft gas turbine engines (GTEs) depending on the filter parameters. It was shown that the filter presence includes systematic error in the measurement of the mass fraction of wear particles independent of the measurement equipment. The influence of the filter parameters on the steady state value of particles mass fraction is discussed. It's shown that in modern engines that use 10 um fine oil filters the mass fraction is less than 0.01 ppm and can't be used as a diagnostic feature for engine technical state evaluation. Oil filter wash samples carry the bulk of the wear particles and consequently, the most diagnostic information. Thus, the oil filter wash sample should be used together with oil sample for reliable evaluation of the technical state of the engine.
