Which inefficiency reduces a turbofan engine's thrust when ice forms?

A)Sublimation lowers engine component temperature
B)Deposition increases boundary layer turbulence
C)Condensation disrupts compressor airflow
D)Fusion increases nozzle exit velocity

💡 Explanation

Condensation of water vapor onto compressor blades increases pressure and disrupts smooth airflow, thus reducing thrust. This occurs because phase transition releases latent heat, increasing instability, therefore impacting thrust rather than direct cooling or turbulence alone.
