Review of Non-contact Blade Vibration Monitoring Based on Blade Tip Timing

In the working state of the aero engine, it is very important to accurately monitor the vibration characteristics of the rotor blades to obtain their operating status, aiming to avoid serious failures such as the fatigue fracture of blades and rub-impact

New microwave sensor for on-line Blade Tip Timing in gas and steam turbines

Real-time Blade Tip Timing (BTT) in rotating machinery enables condition-based maintenance and blade failure prevention. In this paper, we propose a new 6 GHz microwave sensing system suitable for BTT in gas and steam turbines.

Vibrations measurements for shrouded blades of steam turbines based oneddy current sensors with high frequency response

Journal of Measurement Science and Instrumentation, 2019
With the development of power plants towards high power and intelligent operation direction, the vibrations or failures of blades, especially the last stage blades in steam turbines, happen more frequently due to the unstable operating conditions brought

A simple algorithm for probes positioning in BTT systems

, 2020
The Blade Tip Timing (BTT), a non-contact method for measuring the blade tip displacement through the time of arrival, is studied in this article. This work proposes a simple algorithm based on the minimization of the coherence and the condition number ...
