Blade Tip Timing Technique: Theoretical Principles and Simulation of an Experimental Test

The Blade Tip Timing (BTT) is a technique that measures the vibration amplitude and frequency of the blades of bladed disks by using a set of probes. The objective of the thesis is to compare the accuracy of the different methods proposed in literature, first on the basis of a simplified benchmark and then by means of real experimental data of a BTT system.
