🔍 Key Concepts

• Turbine surge and how it affects airflow and pressure in the compressor/turbine stages • What kind of problem would cause interrupted or pulsating air flow to the turbine • Which conditions are more likely to create a sudden pressure change rather than a gradual mechanical failure

💭 Think About

• Think about which choice would most directly disturb the steady flow of air through the turbine and cause pressure pulses that might sound like barking. • Consider which problems typically develop slowly and cause vibration, noise, or reduced efficiency, versus which can create sudden, rhythmic surging noises. • Ask yourself: which option would most likely interfere with the engine’s breathing (air supply) rather than with its lubrication or rotating parts?

✅ Before You Answer

• Verify which fault would most likely cause airflow restriction or instability rather than purely mechanical wear. • Check which of the listed issues would usually show up first as vibration, heat, or bearing noise instead of a barking or surging sound. • Confirm that surging in turbines is commonly linked to compressor/airflow problems, not primarily to lube oil issues.
