As a promising way of on-line and non-intrusive blade vibration monitoring, the blade tip-
timing (BTT) technique is currently being explored by almost all gas turbine or aero-engine …

Progress in the design and structural analysis of commercial jet engine fan blades is
reviewed and presented. This article is motivated by the key role fan blades play in the …

Severe blade vibrations may reduce the useful life of the high-speed blade. Nowadays, non-
contact measurement using blade tip-timing (BTT) technology is becoming promising in …

The need for non-destructive testing/structural health monitoring (SHM) is becoming
increasingly important for gas turbine manufacturers. Incipient cracks have to be detected …

Dynamic strain measurements of rotating blades have attracted significant attention in the
turbomachinery design, testing, and service stages. Measuring the blade full-field strain …

Abstract The Blade Tip-Timing is a well-known non-contact measurement technique
currently employed for the identification of the dynamic behaviours of rotating bladed disks …

Abstract Blade Tip Timing (BTT) method is increasingly implemented for rotating blade
health monitoring for its non-contact property. However, the BTT data is usually highly …

Blade tip-timing is the most effective method for blade vibration online measurement of
turbomachinery. In this article a synchronous resonance vibration measurement method of …

The accurate monitoring of blade vibration under operating conditions is essential in turbo-
machinery testing. Blade tip timing (BTT) is a promising non-contact technique for the …

Abstract The Blade Tip Timing (BTT) measurement system is a technique to measure
vibration parameters of a rotating bladed disk. In particular for synchronous vibrations the …
