turbo fans when you explain them sound like a troll physics meme
turbojets are basically rockets.
"hey we're wasting a lot energy making a bunch of hot gas shoot of of the exhaust really fast, why don't we put a turbine in the exhaust and the hot gas can turn a really big fan instead? the fan will then push even more air! let's call it a turbofan."
this actually works and makes the plane more efficient.
the plane engine running creates exhaust. this exhaust is drives a fan. that fan is hooked up to another fan that blows more air into the engine. which makes more exhaust gases which help drive the fan more. it’s a really clever hack and it sounds like free energy (google search “turbofan” for an appropriate diagram to accompany this description)
