Feasibility of Vibration Diagnostics Measurements in a Gas Turbine Engine

摘要

A variety of analytical and experimental techniques has been explored to determine the efficacy and viability of application for diagnostics of a tank gas turbine engine. Engine performance criteria, along with mechanical maintenance programs, have been identified to be used in the turbine engine diagnostics program. Fast-Fourier analysis, Hilbert transforms, wavelets, and Kurtosis techniques were explored as the governing tools in determining engine functionalities. A proof-in-principle test was performed via spectrum analysis that clearly illustrated that a signal-rich environment, as provided by the measurements performed in this specific study, is required for engine performance analysis and diagnostics.
