Published Online: August 1, 2019
Fig. 1 Autocorrelation function of the AE signals plotted for 1000 time samples corresponding to three actual different gas turbines of the same make, type, and size, but operating under different conditions. All the three plots depict a sinusoidal waveform of equivalent frequency, that is, the ro... More

Published Online: August 1, 2019
Fig. 3 AE samples of the gas turbine with the gearbox problem is appended to the AE sample of the healthy gas turbine at the time instant (indicated on the time axis at “Fault Starts Here”) in each subplot. The appended signal was then decomposed into eight detail levels using WPD. The highest fre... More
