Title:
SYSTEM AND METHOD FOR MONITORING HOOK WEAR IN A GAS TURBINE ENGINE
Document Type and Number:
WIPO Patent Application WO/2018/160270
Kind Code:
A3
Abstract:
A system and method (90) for monitoring a gap size of a gap (38) between a seal holder (28) and an adjacent disk (14) in a compressor section (10) of a gas turbine. An imaging device (50) is used to generate at least one image of the gap, wherein a calibration image of the gap is generated when the gas turbine is in a cold state to provide a calibration gap size. An operational image of the gap is also generated when the gas turbine is in operation to provide an operational gap size. In addition, an enclosure (54) that houses the imaging device is attached to an access port (86) formed in the compressor section to provide a view of the gap for the imaging device. Wear is detected in a hook section (26) of the compressor section when the operational gap size is less than the calibration gap size.
