Calibration of blade tip-timing sensor for shrouded 40″ last stage blade

Mechanical Systems and Signal Processing, 2018
Abstract Today’s power generation market requests steam turbines of high efficiency, reliability and wide operation range. The last stage moving blades are designed with integral shroud, mid-span, and fir-tree dovetail. The blades are continuously coupled by the blade untwist due to the centrifugal force, and thus the vibration control and increased ...

Blade Crack Detection using Blade Tip Timing

IEEE Transactions on Instrumentation and Measurement, 2021
The harsh working environment of compressor threats the integrality of bladed disk. Crack is one of the most fatal faults of rotating blades. Detecting the crack of blades at early stage could ensure the safe operation of gas turbine and save economic costs.

An OPR-Free Blade Tip Timing Method for Rotating Blade Condition Monitoring

IEEE Transactions on Instrumentation and Measurement, 2021
Blade tip timing (BTT) is a noncontact blade vibration measurement method for rotating blade condition monitoring. However, it is difficult to install a once-per-revolution (OPR) probe due to the internal environment limitation of an engine. To solve this problem, an OPR-free BTT method is proposed in this article.

An OPR-free Blade Tip Timing Method Based on Blade Spacing Change

2020 IEEE International Instrumentation and Measurement Technology Conference (I2MTC), 2020
Compressor blades often operate in high temper-ature, high pressure, and heavy load environments. They are in direct contact with the outside air, which causes their life to be severely limited. Blade vibration is an important factor that reflecting the state of the blade. Therefore, effective blade vibration monitoring methods are needed.
