← TechnologyWhich outcome occurs when anti-stall control valve in turbofan engine fails closed during takeoff?
A)Compressor surge due turbulent airflow✓
B)Increased fuel efficiency from greater thrust
C)Lower exhaust gas temperatures saving turbine
D)Reduced engine noise benefiting passengers
💡 Explanation
When the anti-stall valve fails closed, compressor stall surge occurs because boundary layer separation happens since airflow through the compressor reduces causing violent bursts and flow reversals. Therefore, a compressor surge occurs, rather than efficiency increase, lower temperature, or less noise, which require different conditions.
