← TechnologyWhich outcome occurs during surge in a compressor?
A)Reversed airflow through compressor stages✓
B)Increased efficiency of heat transfer
C)Stabilized core engine combustion rate
D)Reduced rate of fuel consumption
💡 Explanation
Surge causes reversed airflow because flow separation exceeds blade airfoil's stall angle of attack; therefore, airflow suddenly reverses direction rather than continuing forward, causing pressure oscillations and potential damage to the compressor blades.
