🔍 Key Concepts

• Study the Stage 2 blades in the illustration and compare them to the Stage 1 blades. • Note where the cooling passages are shown exiting the blade (look for labeled holes/slots). • Remember that convection cooling means air flows through internal passages and is discharged back into the hot gas path.

💭 Think About

• Which specific discharge openings are clearly labeled on the Stage 2 blade but not necessarily used the same way on Stage 1? • Do you see any markings for cooling air at the blade tip, leading edge, or side, or only at one particular edge? • If cooling air travels inside the blade, at what edge would it be most effective to discharge it to cool both the blade and the gas flow behind it?

✅ Before You Answer

• Verify which features (gill holes, nose holes, trailing edge features, blade tips) are actually drawn and labeled on the Stage 2 blade. • Confirm that the feature you choose is shown as an opening to the gas path, not just a structural part of the blade. • Make sure your choice matches the labeled discharge location for cooling air on the Stage 2 blade in the diagram.
