Which component is responsible for producing thrust by mixing bypass air with core exhaust?

• A. Intake
• B. Low compressor
• C. Exhaust
• D. Combustion

Answer: (C)

Thrust from a turbofan comes from accelerating air in both the bypass flow and the core exhaust, and the mixing of those two streams happens in the exhaust path. The exhaust section, often with a mixer, is where the bypass air and the core exhaust are combined before leaving the engine, producing the final jet that generates thrust. So the exhaust is the part responsible for this mixing and for producing the thrust from the combined jet. The intake only brings air into the engine; the low compressor raises pressure in the core flow; combustion adds energy to the core gases. The mixing of bypass air with core exhaust occurs after combustion, in the exhaust/mixer area.
