The original announcement has more information about this: https://boomsupersonic.com/flyby/post/introducing-symphony-t...

It seems Boom designed some engine ideas and is now partnering with other companies to see if it can be built.

This sounds a little like Magic Leap. Sell great ideas and then conclude it can't be made (yet).

"35,000 pounds of thrust" Can anyone compare this to other commercial and military engines?

Air speed is an important aspect in this conversation. The air going into a 747's engines isn't travelling at supersonic speeds. For reference, the Concorde's Rolls Royce Olympus 593 engines did 35,190 lpf and it had four.

It's very disappointing to see how skeptical HN has become about new technology.

Making aircrafts is hard, making supersonic aircraft even harder and making a new supersonic aircraft company hardest of all. That there's progress by Boom should be encouraged. Otherwise we are just saying that aircrafts will continue to be the domain of Airbus and Boeing only who don't have much incentive to innovate.

Completely made up nonsense with no evidence is not "new technology".

> That there's progress by Boom

Is there though? PR is not progress.

I want to believe but my B.S. detector is pegged at 11 with this company.

> The Symphony engine will be designed from scratch by Boom’s partners: Florida Turbine Technologies (a subsidiary of Kratos) will do the engine design proper, GE Additive will consult on manufacturing, and StandardAero will be on maintenance duty. (FTA) They're (Boom) not the ones designing it. Kratos Turbine Technologies has made turbopumps for liquid rockets so they're well placed to do this work. The hard part is…

Interestingly, it's not GE Aviation (the GE division who make engines) but GE Additive, a division of GE who specialise in Additive manufacturing (aka 3D printing) metal parts.

So it's going to have 3d printed rotors and probally other , which is super cool.

GE Additive have previously made 3d printed turbine parts for GE Aviation[1], so they do have some experience. Also, this appears to be Kratos' second jet engine [2]

It's built specifically for an alternative consumable, the largest expensive of a flight right?, that cost SEVERAL TIMES what the standard consumable costs right now? That's a.. Forward looking design.

SAF is generally made to be compatible with regular jet fuel so I would expect it should work with either, even if it’s optimised for a particular type of SAF.

HN was very sceptical about blockchain/web3, and recent events show that HN was quite rightly so ...

The technology was already solved decades ago, we had the Concorde. Supersonic flight is well understood. The hard part is to make a supersonic aircraft that's commercially viable.

Personally, I'm very skeptical when they say things like "zero carbon" or "anywhere in the world for $100", very difficult to believe them. The only progress they made for now is building a single seat supersonic plane that maybe will fly. We have lots of those already.
