🔍 Key Concepts

• Gas turbine blade cooling methods in the turbine section • Difference between internal cooling and air flowing around the blade externally • Which working fluid in a gas turbine remains clean, non‑corrosive, and available at high pressure and temperature for reuse as cooling air

💭 Think About

• Look at the illustration: does the fluid seem to enter from inside the rotor/disc and then exit through small holes in the blade surface, or does it wash over the outside only? • Of the four choices, which fluid is already present at high pressure in the engine and can be safely routed through very small passages close to extremely hot metal? • Which fluids, if leaked from these internal passages into the hot gas path, would create serious problems such as fires, corrosion, or blade erosion?

✅ Before You Answer

• Verify which working fluid is normally tapped from the compressor specifically for cooling hot‑section components • Eliminate options that would be liquid in these conditions and consider what phase the coolant must be to pass through tiny holes and films • Consider whether the term "external" in one option matches the clearly internal passages labeled in the illustration
