What is TMI Compressor Failure Analysis about?

Most gas turbine compressors experience failures of blades and vanes due to foreign object damage, operational issues, and fretting wear from factors like protruding shims and loose stator vanes. Protruding shims in particular can cause high vibratory stresses in rotor blades by up to 2.5 times through resonant forcing at specific rotational speeds. Loose stator vanes from fretting wear in the casing also present risks like liberation and impacts with rotor blades. Pinning stator vanes together to maintain
