🔍 Key Concepts

• Location of ice prevention or anti-icing systems on gas turbine air intakes • Purpose of inlet duct design versus stack/exhaust ducting • Where air must be treated before reaching the compressor to prevent damage

💭 Think About

• Ask yourself: On a gas turbine, where does ambient air first enter and get conditioned or treated before going to the engine? • Would anti-icing provisions be more critical before the compressor or in the exhaust path, and why? • Think about which components actually see freezing moist air versus hot gases where ice cannot form.

✅ Before You Answer

• Identify which choice(s) refer to inlet/intake air surfaces before the engine • Consider whether ice can realistically form and remain in any part of the hot exhaust path • Check which option(s) place anti-icing measures where they will protect the compressor and blades from ice ingestion.
