← ScienceWhich risk increases when a two-stage turbine engine's intercooler fails?
A)Blade erosion from water droplets
B)Compressor stall due to backflow
C)Increased NOx formation downstream✓
D)Elevated SOx emissions released aloft
💡 Explanation
Increased NOx emissions arise from higher combustion temperatures after the intercooler fails, because the absence of cooling raises inlet temperature; therefore, thermal NOx formation increases rather than droplet erosion or stall based on pressure variations.
