🔍 Key Concepts

• Brayton cycle steps in a gas turbine engine • Difference between compression vs. decompression in engines • What actually happens during combustion in a turbine (steady burning vs. sudden explosion)

💭 Think About

• Think about how air moves through a typical gas turbine: what happens to its pressure before fuel is added? • During normal turbine operation, is the burning of fuel closer to a controlled, continuous burn or a sudden explosion? • In a power-producing turbine, after combustion, what do the hot gases do before they leave the engine?

✅ Before You Answer

• Make sure the sequence includes compression (pressure increase) rather than pressure drop before combustion. • Ensure that after combustion there is a phase where gases expand to do work before exiting. • Eliminate any option that suggests an explosion rather than controlled combustion in a continuous-flow turbine.
