Question 1 of 27070

In which of the following ways can compressor surge cause excessive temperatures in the turbine section?

🔍 Key Concepts

• Compressor surge and what happens to airflow through the engine when it occurs • Relationship between primary combustion air and secondary cooling air in a gas turbine • How airflow interruptions or instabilities affect turbine blade temperatures

💭 Think About

• When a compressor surges, does the flow through the combustor and turbine become more stable or more disturbed? How would that affect turbine cooling? • Which option(s) would tend to increase turbine inlet temperature or reduce cooling rather than cool the turbine? • Think about what “secondary air” is used for in a turbine. If that air changes (too much or too little), what happens to metal temperatures?

✅ Before You Answer

• Be clear on the difference between combustion/primary air (supports burning fuel) and secondary/cooling air (protects metal parts). • Consider whether compressor surge is more likely to cause too much air, too little effective flow, or erratic flow to the combustor and turbine. • Check which choice(s) would realistically raise metal temperatures in the turbine rather than help cool them.
