Standard Sine Fitting Algorithms Applied To Blade Tip Timing Data

Standard Sine Fitting Algorithms Applied To Blade Tip Timing Data

Blade Tip Timing (BTT) is a non-intrusive method to measure blade vibration in turbomachinery. Time of Arrival (TOA) is recorded when a blade is passing a stationary sensor. The measurement data, in form of undersampled (aliased) tip-deflection signal, are difficult to analyze with standard signal p...
