ACTMS

The Acoustic Combustion Turbine Monitoring System (ACTMS) is designed to detect cracking in mid-compressor stator vanes of natural gas/oil fired combustion turbines using an online Acoustic Emission (AE) system. ACTMS, using noninvasive sensor mounts, shows AE is capable of detecting and identifying crack activity in the presence of normal turbine operational noise.

Mid-compressor vane cracking is an industry recognized problem wherein at its later stages, blade liberation can cause total catastrophic loss of the compressor. The losses from these failures are between $7 and $10 million per incident.
