🔍 Key Concepts

• Compressor rotor vs. stator blades – which ones rotate and which are fixed • Purpose of midspan shrouds in gas turbines (vibration damping and stiffness) • Where a shroud is located on a blade: at the tip, at the root, or somewhere in between

💭 Think About

• First, decide whether a midspan shroud would more likely be attached to moving (rotor) blades or stationary (stator) blades, based on what typically needs vibration damping. • Think about why long, thin blades might need extra support in the middle and what shape or structure would provide that support. • Compare each option: which choices describe a function related to vibration damping or bracing, and which describe something else (like securing or joining parts)?

✅ Before You Answer

• Verify which components in a compressor are rotating (rotor) and which are fixed (stator). • Check which answer choices actually mention something in the middle of a blade span rather than at the root or tip. • Confirm which option clearly connects to damping vibration or stiffening long blades rather than just holding blades in place.
