Which 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.
