🔍 Key Concepts

• Carefully trace the arrows labeled 13th Stage Bleed and 13th Stage Cooling in the GT-0017 illustration to see exactly where that air is routed. • Compare how 8th stage and 9th stage bleed air are used (their labels and destinations) versus the 13th stage; each stage usually serves a different function (sump pressurization, cooling, thrust balance, etc.). • Think about which engine sections typically require the highest-pressure compressor bleed air versus those that can use lower or intermediate stage bleed.

💭 Think About

• On the diagram, where does the arrow marked 13th Stage Bleed actually end up? Does it go toward sumps, turbine nozzles, or a balance piston area? • How is sump pressurization/cooling supplied in this illustration—what stage bleed is specifically tied to that label? Does the same pathway also show 13th stage bleed, or a different stage? • Look for any text near the power turbine and high-pressure turbine that mentions cooling or balance piston pressurization; which stage bleed is named there?

✅ Before You Answer

• Verify which label on the diagram is directly connected to the text near the 13th stage bleed arrow (don’t mix it up with 13th Stage Cooling). • Confirm what function is explicitly tied to 8th Stage Bleed and 9th Stage Bleed; eliminate any answer choices that belong to those stages instead of the 13th. • Before choosing, make sure the function you pick is clearly shown in the illustration as being fed by 13th Stage Bleed, not just by a nearby cooling or vent line.
