Re: Unique
I do wonder whether its ignored in case the technology got a bit open-sourcy.
Thinking up a rocket engine for a particular fuel/oxidiser combo isn't too difficult.
Designing one is a bit harder.
Building one that actually works, keeps working and doesn't scatter itself and whatever it's attached to all around the test site or the launch pad appears to be still somewhat of a challenge, hence the marked preference to just go with one that's been shown to do what it's supposed to, unless one has very specific requirements.
