🔍 Key Concepts

• Compressor blade platform – what part of the blade this is and where it sits relative to the root and tip • Typical signs of a blade root failure vs. a tip or damper problem • What a tilted or raised platform physically suggests about how the blade is attached or supported

💭 Think About

• Think about how the blade is held in the disk: if the attachment at the hub end loosens or cracks, which visible part of the blade is most likely to move or tilt? • Which of these options (midspan damper, tip clang, blade root, carboloy pad) is directly related to the structural attachment of the blade to the rotor? • If the platform is raised or tilted, does that suggest a problem at the mid‑length of the blade, at the tip, or down at the base where it locks into the disk?

✅ Before You Answer

• Identify which choice refers to the primary structural connection between blade and disk • Eliminate any options that are not directly part of the blade/platform assembly or do not affect platform position • Visualize how a failure at each named component would change the alignment or height of the blade platform
