Question 1 of 27070

When a compressor is in a stall condition, what will happen to the combustor and turbine temperatures?

🔍 Key Concepts

• compressor stall and its effect on airflow through the engine • relationship between airflow, fuel flow, and temperature in a gas turbine • how reduced airflow with similar fuel flow affects combustor and turbine inlet temperature

💭 Think About

• Think about what happens to the amount of air moving through the compressor and into the combustor during a stall. • If the fuel flow initially stays about the same but the mass of cooling air drops, what happens to the temperature in the combustor and at the turbine inlet? • Would the temperature change be sudden or gradual when normal airflow is suddenly disrupted?

✅ Before You Answer

• Confirm what a compressor stall does to engine airflow (increase or decrease?). • Consider whether fuel control responds instantly or with some delay when a stall first occurs. • Decide if the resulting temperature change at the combustor and turbine will be rapid or slow, and in which direction.
