I could be compelled to agree, but "An air-breathing turbojet engine of that size..." doesn't have the same ring to it. Jet engine usually refers to something that has the traditional suck, squeeze, bang, blow method of propulsion, and rocket engine is used to refer to something that just burns straight fuel (with its own oxidizer, etc.).

Technically my air compressor blow gun is a rocket, but I wouldn't ever refer to it as one.

But hey, language evolves, so maybe being hyper specific will catch on.

While this broad definition may include rocket, water jet, and hybrid propulsion, the term jet engine typically refers to an internal combustion air-breathing jet engine such as a turbojet, turbofan, ramjet, pulse jet, or scramjet. In general, jet engines are internal combustion engines.

Huh, TIL!

A jet engine is a type of reaction engine, discharging a fast-moving jet of heated gas (usually air) that generates thrust by jet propulsion.
