This not a typical low-bypass, cigar-type turbofan jet engine you see on airplanes, rather, it’s a modified turboshaft jet engine used for helicopters, intended to provide longitudinal rotational energy. The air it moves from the intake is a fraction of what it produces as the combustion process itself results in gasses being chemically formed. There is no propeller or fan on this engine - it’s closer to a rocket than what we think of as a jet.

The air it moves from the intake is a fraction of what it produces as the combustion process itself results in gasses being chemically formed. It's not a turbofan no but it's a jet engine burning fuel the regular way (using air), like the ones on a B-52 or Concorde. Very different from a rocket engine that carries its own oxidiser.
- samtho 3y agoI’m fully aware of the difference. The only parallel I’ve drawn is the fact that it uses gases as a result of the combustion as propulsion rather than spinning a fan. Whether it has its own oxidizer is irrelevant for the purposes of this analogy as I don’t see this vehicle achieving any sort of space flight.
