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

#12So these are their new partners after Rolls-Royce dropped them [1]? Hopefully it works out this time. This is a very hard problem, and they're outsourcing one of the most critical components. [1] https://denvergazette.com/news/business/colorado-s-boom-supe...
With this announcement, I wondered to myself which party decided to end the partnership?
It's highly probable that Rolls-Royce left the deal, and not vice versa, but the GP press release leaves that question unanswered.

Google says "The most recent model, the 747-8, has engines that produce 66,000lbs of thrust."

#14How much time was wasted in meetings to come up with "symphony" for the name of their engine. Who gives a crap what the engine is called? Just give it a serial number and be done with. Edit: By serial number I mean some insignificant labelling instead of a marketing campaign. Sell me the supersonic trip not the engines that you have to build to make it work.
It doesn't exist yet, hard to meaningfully put a serial number on a rendering.
Edit: Investors is their audience for this announcement, less so potential customers.

Every aircraft manufacturer outsources their engines to other manufacturers. This is normal in the aerospace industry. Even rockets have motors made by different companies most of the time.
As far as this particular project goes though, I would have a hard time expecting it to succeed. They have a great number of hurdles to overcome, and the engine design has to be the biggest one. Designing an engine that can work efficiently in both subsonic and supersonic regimes without an afterburner is very very difficult.

A popular turbofan with civilian fighter jets is the TFE731 with 3,500–4,750 lbf [1] and can be fitted to i.e. the L39 Albatross trainer jet. [2]
Supersonic jets like the F5 might use something like the GE J85 which produces a base 3,500 lbf or 5,000 with an afterburner [3].

#19I want to believe but my B.S. detector is pegged at 11 with this company.
That conceptual render is so laughably bad that it reeks of a designer copying a turbine schematic from Wikipedia, but they don’t even know how an axial turbine works or what a stator is. The schematic is similar to a turbine engine in the same way Fred Flintstone’s car resembles a modern automobile. This is looking theranos bad.

A bit less than an F-35 engine, a bit more than a single 737 engine.
