Methodology for confirming the safety of operation of the drive box and the central drive of prospective engines, based on tribology

Abstract

In this paper, three ways to prevent increased wear of parts of the drive box and the central drive of a civil aviation gas turbine engine, based on tribology, using methods such as ferrography, filterography and computer analysis of the classification and calculation of wear particles were considered. Investigations of the results obtained by these methods revealed the circumstances that would allow in advance to prevent the occurrence of an emergency and, therefore, can form the basis of the methodology. This technique, based on the analysis of the parameters of wear particles in oil, belongs to the group of methods for non-destructive testing of the technical condition of machines and mechanisms.
