← ScienceWhich outcome reduces jet engine compressor stall due to choked airflow?
A)Bleed air system activation✓
B)Increased combustion chamber pressure
C)Decreased turbine inlet temperature
D)Reduced fuel flow rate
💡 Explanation
Activating the bleed air system decreases pressure thus allowing the inlet airflow to stabilize; this prevents stall, because boundary layer separation decreases from reduction in adverse pressure gradient across the airfoil, therefore stall is minimized rather than intensified due to the changed aerodynamics at the inlet.
