← ScienceWhich outcome occurs when airflow exceeds a turbofan's design limit?
A)Compressor stall and flow reversal✓
B)Increased thrust efficiency at altitude
C)Fuel consumption becomes consistently lower
D)Stable laminar flow in bypass duct
💡 Explanation
Exceeding design airflow causes compressor stall because boundary layer separation initiates turbulence, disrupting the smooth flow. Therefore, stall and flow reversal occur, rather than efficiency increase. That mechanism requires controlled conditions.
