Morphology
The meaning 'a type of jet engine...' is directly and transparently derived from combining 'turbofan' (a fan-driven turbine concept) with 'engine' (a machine that produces mechanical power); the phrase simply names a kind of engine. This is a literal noun + noun classificatory pattern found across languages, so a B1 learner who knows both constituents would readily infer the MWE meaning.
Etymology
Turbofan engine comes from the two parts you can picture: a fan at the front and a turbine, a wheel inside that turns. The big fan pushes extra air to give more 'push' and to save fuel, so the name helps you remember that this engine makes more power and uses less fuel.
