As a result of experimental and theoretical studies performed, a number of new results significantly expanding the possibilities of assessing the technical condition of gas turbine engine planetary gearboxes was obtained. The simulation model of the “sun gear/satellites” couple vibration under propagating wear of tooth flanks, a model of the width of the spectral line of the tooth component of the gear couple under review, as well as the widths of the spectral line of rotation frequency of the gearbox output shaft in the vibration process and the signal of a regular tachometric sensor of its rotation, were proposed. New methods of analyzing dynamic processes were developed. The developed mathematical models, new methods of analyzing dynamic processes made it possible to propose a package of new diagnostic indicators of teeth wear and the values of backlash in a gear coupling. Recommendations on setting standards for the developed diagnostic indicators were given.
