🔍 Key Concepts

• Effects of fouling and contamination on gas turbine compressors and turbines • Relationship between airflow, temperature, and fuel flow in turbine performance • Normal vs abnormal indicators of efficiency (what increases vs what decreases when the turbine is dirty)

💭 Think About

• If the compressor and turbine passages are getting dirty and rough, what happens to how easily air can flow through the engine? • To maintain the same power with less efficient airflow, what must happen to fuel flow and internal temperatures? • Which option describes something that would usually improve efficiency instead of hurting it when contamination builds up?

✅ Before You Answer

• Identify which options clearly describe performance losses (reduced airflow, higher stress/temperature, damage) • Decide which choice would normally be associated with better fuel efficiency, not worse, when comparing to a clean engine • Ask: with more contamination and fouling, does the engine usually burn more or less fuel to get the same power?
