Diagnosis of bearing installation damage in gas turbine engines

Abstract

The work is devoted to solving the problem of constructing a measuring channel based on an analog interface for diagnosing damage to bearing assemblies in gas turbine engines at an early stage of their occurrence. The reliability of gas turbine engines (GTE) is due to the durability of elements and components, which during operation are under the influence of mechanical, acoustic, gas and temperature loads. One of the key components of the gas turbine engine is a bearing assembly, namely a rolling bearing. An important task of practical diagnostics is to improve methods and means of vibrodiagnostics of bearing assemblies in the gas turbine engine at an early stage of damage (defects) based on the construction of a measuring channel with improved metrological characteristics.
