← ScienceWhich outcome occurs when a jet engine exceeds design airflow creating back pressure?
A)Compressor stall initiates flow reversal✓
B)Turbine blade creep dramatically reduces
C)Combustion efficiently increases greatly
D)Nozzle efficiency prevents excess turbulence
💡 Explanation
Compressor stall initiates because airflow disruption causes boundary layer separation, leading to rotating stall. This flow reversal is due to the loss of aerodynamic lift from the stalled compressor blades; therefore stall results, rather than the alternatives, because the engine is forced beyond its design limits.
