🔍 Key Concepts

• Gas turbine engine (GTE) start sequence – how RPM, fuel flow, and temperature normally change during start-up • Definition of a hung start vs a normal start and a hot start • Relationship between compressor speed (RPM) and turbine/exhaust temperature when fuel is added

💭 Think About

• Think about what happens if the compressor RPM stops increasing during start while fuel is still being supplied. How does that affect temperature and airflow? • Compare the airflow available for cooling at low RPM with the amount of fuel being burned. What happens to turbine or exhaust temperatures in that case? • Which option describes a condition that is more likely when air is not increasing but fuel/heat is present during startup?

✅ Before You Answer

• Make sure you understand that in a hung start, RPM increases at first, then stops climbing and stays low instead of reaching normal idle speed. • Double-check which choices describe a change in temperature vs speed, and which one best matches low airflow with continued fuel burn. • Verify that a hung start is NOT the same as an overspeed condition, so eliminate any option that implies excessively high RPM.
