Compressor Blade Tip Timing Using Capacitance Tip Clearance Probes

Volume 1: Turbo Expo 2003, 2003
Turbomachinery blade vibrations of sufficient amplitude cause High Cycle Fatigue, which reduces blade life. In order to observe this vibration a non-intrusive monitoring system is sought. The vibration can be detected by measuring blade tip timing since in the presence of vibration the blade timing will differ slightly from the passing time calculated ...

Blade tip clearance measurement method based on blade tip timing without the once per revolution sensor

Measurement Science and Technology
Abstract The rotor blade tip clearance (BTC) of an aeroengine is a critical parameter that significantly impacts its performance and safety. Accurately determining dynamic BTC has been a focal point of research in experimental testing. Among the effective measurement methods for dynamic BTC, the laser triangulation method based on blade ...

Blade Tip Timing: from Raw Data to Parameters Identification

2019 IEEE International Instrumentation and Measurement Technology Conference (I2MTC), 2019
Blade Tip Timing (BTT) methods have been increasingly implemented for blade health monitoring. However, most of them are based on the prior knowledge that the resonance’s location is known. Since real BTT test usually takes more than ten hours, it’s unrealistic to Figure out every resonance from the measured raw data manually.

Blade-Tip Timing Measurement Of Synchronous Vibrations Of Rotating Bladed

2002
Blade-tip timing (BTT) is a promising method for the detection, measurement and analysis of blade vibrations in rotating bladed assemblies. However, the intricacies of the method when applied to real rotating structures undergoing synchronous (Engine Ordered) vibrations are not yet fully understood.

A blade damage identification method based on bladed disk modal analysis and blade tip timing

Aerospace Science and Technology
Blade damage diagnosis is a critical requirement for ensuring operational safety and reliability in aero-engines and gas turbines. Blade tip timing (BTT) is a well-established non-contact vibration monitoring technique. However, most existing damage detection methods focus on single-blade response analysis, which suffers from diagnostic latency and can
