On the development of a magnetoresistive sensor for blade tip timing and blade tip clearance measurement systems

AIP Conference Proceedings, 2014
A simultaneous blade tip timing (BTT) and blade tip clearance (BTC) measurement system enables the determination of turbomachinery blade vibrations and ensures the monitoring of the existing running gaps between the blade tip and the casing. This contactless instrumentation presents several advantages compared to the well-known telemetry system with ...

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

Validating Blade Vibration Amplitudes from Blade Tip-Timing Data Analysis

2004
Blade Tip-Timing (BTT) is a method for the measurement of blade vibration in rotating bladed assemblies such as those found in turbomachinery. BTT data needs to be analysed by specially formulated methods, to yield the vibration frequencies and amplitudes.
