I'm rooting for you, Boom. The world needs supersonic planes and you're so close. Good luck.

There is no engine that will make economic sense for either the engine manufacturer or the airline operator based on the technology we have. This was always a fools errand.
No engine product ready for purchase or no engine that could ever be built? If the former, whatever tell R&D to go do their job. If the latter, maybe it was a scam. Which is it?
Regarding Boom there are only two reasonable conclusions one can reach: 1. They are a Theranos-style operation 2. They are a Madoff-style operation I, a lone aerospace engineer working out of my garage in my spare time, have a better chance of achieving supersonic flight than Boom does. Even their technology demonstrator is an obvious scam. It demonstrates nothing. It does not demonstrate the ability to design, build…
If they were that, they'd be lying about having their own engine in development that is an order of magnitude better than the competitions but won't show it to anybody.
How surprising... Developing a specific supersonic jet engine for this kind of plane would not be cost effective anyway, the fleet would be too small to worth the investment. Even starting from a military jet engine, the way they are run and maintained is very different from civilian jet engines.

As an aerospace engineer do you know what kind of thrust they'd need and why they can't just use something like the https://en.wikipedia.org/wiki/Pratt_%26_Whitney_J58#Specific... ? My guess would be that the military engines are not at all designed to be economical on either fuel or unit cost.

Those aren’t jet engines.
It's a pity there aren't more jet engine providers.

Can they use for test demonstrator something like Mig-29 engines - those used planes are available including in US just for few millions. Once they are flying, GE or RR will probably be more interested.
It's true that a lot of aircraft development has occurred using substitute engines while the final engines where still being developed. The problem for Boom isn't getting airborne. It's convincing one of the few outfits capable of this to put billions of dollars into a clean sheet engine design. Klimov RD-33's (the Mig-29 engine) are not super-cruise engines and aren't capable of demonstrating the intent of the Boom…

Only for a few industries, mostly the ones that took off around WWII.
Uh… DARPA, In-Q-Tel, etc…
Edit: and there are entire industries, like petrochemicals, where most of the advances came from industry.
