← ScienceWhich consequence results when adiabatic pre-cooling fails in a turbojet engine?
A)Compressor stall risk markedly increases✓
B)More NOx forms internally in burner
C)Turbine blade fatigue weakens acutely
D)Unburnt fuel condenses in the nozzle
💡 Explanation
Compressor stall risk elevates dramatically, because reduced air density lowers the surge margin, and adiabatic pre-cooling maintains inlet density through evaporative cooling to suppress boundary layer separation, generating unstable airflow; therefore stall results, rather than other changes at exhaust.
