Vibration analysis of running-up turbine engine GTD-350

The article contains the example of practical application of the procedure for non-stationary signals processing developed at Department of Mechanics and Vibroacoustics University of Science and Technology (AGH). The developed method – Procedure of Linear Decimation (PLD) was applied for signal analysis of vibrations of GTD–350 turbine engine in unstable operating conditions. As a reference signal the rotational speed of driving shaft was adapted. The results were enclosed for turbine running-up and coasting state.
