This paper presents results of an investigation to assess the potential of the acoustic emission (AE) technology for detecting seal-to-rotor rubbing in power generation turbines. The experimental program involved inducing rubs at various axial locations along a 412ton test rotor, rotating at 3000rpm and supported by 7in.(178mm) journal bearings. Whilst there was no change in vibration levels throughout the tests, bearing mounted AE transducers successfully detected all rubbing induced on the rotor.
