    • Detection of Broken Blade on Compressor 
      Yu, John J.; Wang, Carl Feng; Yuan, Mingfeng; Peton, Nicolas; Guan, Xiaodong (Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)
      A sudden step change in vibration was observed on a 7400 rpm compressor with direct amplitude from 43 um pp to over 62 um pp (trip level) at NDE, thus tripping the unit Vibration reached over 120 um pp at 4000 rpm, compared ...
    • ELECTROSTATIC  DISCHARGEâ€� STG  COMPRESSOR 
      Ponnanna, Bopanna Pudiyokada; Yu, John J.; Peton, Nicolas (Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)
      Electrostatic discharge (ESD) can cause catastrophic mechanical damage and lower the life span of an asset if not detected early and rectified. Continuous discharge of static electricity can cause micro pitting of bearing ...
    • SILO EXHAUST FAN – STRUCTUAL VIBRATION  ODS AND MA 
      Ponnanna, Bopanna Pudiyokada; Yu, John J.; Drygin, Sergey; Peton, Nicolas; Schluter, Steven (Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)
      This case study outlines how structural vibration was resolved using two different technologies and highlighting secondary issues that can arise due to continued vibration because of structural resonance. Continued high ...
