Abstract: Blisks are utilized by most modern aircraft turbine engines to reduce the weight of rotors and eliminate air leakage between platforms. Ring dampers are widely used to reduce the vibration of blisks and avoid high-cycle ...

Abstract: Blade tip timing (BTT) measurement technology is more widely used to determine the vibrational stress of rotating blades and play an important role for blade service life prediction. The dynamic blade displacements can be ...

Abstract: The relationship between the tip clearance flow (TCF) and the blade vibration in the lock-in region was numerically investigated on a transonic rotor. Both the bending (1B) and torsional (8th) modes were analyzed under 0 ...

Abstract: The mistuning effects on the aeroelastic stability of axial compressor rotor blades have been investigated by employing aeroelastic eigenvalue method. An axial compressor rotor suffered from flutter failure has been analyzed ...

Abstract: The tip clearance effects on aeroelastic stability of axial compressor blades are investigated with two independent threedimensional (3D) flutter prediction approaches: energy method and aeroelastic eigenvalue analysis. ...

Abstract: Blade tip timing (BTT) measurement has been used to measure the vibration of turbomachinery blades in recent years. People researches focus on the development of processing methods. Newly developed BTT processing methods ...
