How do turbine fan engines produce thrust?

Turbine fan engines generate thrust through a process that primarily involves compressing air, heating it, and then expelling it at high speed. In detail, the engine first draws in a large volume of air through the fan at the front. This air is then compressed by multiple stages of compressor blades, which increases its pressure and temperature.

After the air is compressed, it enters the combustion chamber where fuel is introduced and ignited, significantly raising the temperature of the air-fuel mixture. The high-energy exhaust gases produced from this combustion process then flow through the turbine section of the engine. The turbines extract energy from the exhaust gases to drive the compressors, but the remaining high-velocity gas is expelled out of the back of the engine.

According to Newton's third law (for every action, there is an equal and opposite reaction), this rapid expulsion of gases creates thrust, propelling the aircraft forward. Thus, the correct process outlined in the answer is an accurate representation of how turbine fan engines operate to produce thrust.
