Popis: The possibilities of vibration diagnostics of high-speed equipment units with gas turbine engines are analyzed under the restrictions determined by the high level of vibration excited by air and gas flows and mutual instability of rotation frequencies of the power turbine and compressor turbines. The approaches to the organization of their diagnosis by vibration signal, taking into account these restrictions are discussed. The first approach is designed for the use of special methods of measurement and analysis of vibration spectra in the operating mode, the second approach is designed for its bench diagnostics when the equipment is rotating by an external drive with a reduced and stable frequency and, accordingly, with a low level of flow noise and without combustion.
