Review of research on tip-timing and tip clearance measurement technology

Turbine blades will fail due to fatigue fracture caused by vibration at high-speed rotation,resulting in damage of rotating machinery.Blade tip-timing measurement technology is the most promising non-contact blade vibration real-time monitoring method at present,and the change of the blade tip clear...
