🔍 Key Concepts

• Basic flow path of a gas turbine gas generator (what happens to the air from intake to exhaust) • Major sections found on a simple- cycle gas turbine engine • Difference between accessories (pumps, gearboxes) and core engine components

💭 Think About

• Think through the steps: how does outside air become high‑energy gas to drive a turbine? List those stages in order. • Which parts are absolutely required in the core for compression, burning, and expansion of the working fluid? • Are any of the listed items optional, or are they all part of the essential core gas generator?

✅ Before You Answer

• Be clear on what the term gas generator means in a gas turbine (it excludes some power‑turbine or accessory items). • Verify which components are involved directly in compressing, burning, and extracting work from the gas. • Check if any answer choice might be too narrow (missing a core element) or too broad (including something that isn’t a core component).
