Abstract
It is shown that, by analogy with combination diagnostic features, in diagnostics of technical condition of gas turbine engines it is possible to successfully use structural diagnostic features as sum or difference of uniform parameters; their use, when analyzing the signals from "standard" tachometric shaft speed sensors, considerably simplifies the procedure for accessing the technical condition of an object under study in comparison with the analysis of vibration processes. As is the case with combination diagnostic features, various characteristics of diagnostic features can be used: the width of spectral components at different levels, the frequency deviation parameters in narrowband processes, and others.
