🔍 Key Concepts

• Compressor construction and where the rotor blades are located relative to stationary parts • The difference between rub that occurs at the blade tip versus at stationary vanes or casings • How foreign object damage (FOD) usually appears on blades compared to gradual wear or contact

💭 Think About

• Which part of the blade would be affected if the rotating blade just barely contacts the surrounding casing during operation? • Does tip curl usually develop suddenly from a single impact, or gradually from continued light contact? • Which choice specifically describes contact at the tip of a rotating blade rather than at a stationary part?

✅ Before You Answer

• Identify which answer options describe contact with rotating blades vs stationary vanes • Consider how light, continuous rubbing at the blade tip would deform the metal over time • Distinguish between localized impact damage (like nicks or dents) and a smooth curl at the blade tip
