eh. IDK about that. The Chinese have closed gaps very fast. To underestimate China would be a huge folly.

ADVENT didn't come out of nowhere. One can only blame their own ignorance if they weren't aware of the program and how it's been close to completion. The gap and this width was always there. It hasn't changed with sudden "announcement" of ADVENT being tested. Again it's been no secret for about a decade. But if China can produce an F135 class engine just in terms of thrust and thermodynamic efficiency, around the same time ADVENT is ready for operations, it would not be such a massive 30+ year gap as suggested. It wasn't that long ago when China didn't even have the ability to engineer the WS-10. The gap between WS-15/F135 class and ADVENT is roughly 20 years if that. It's not that much more of a materials hike but a physics and engineering one. Lots of testing, trial and error.
It would be interesting to see how much of that was real experimentation, development and testing and how much of the 20 year time difference was due to the US procurement system's inefficiencies.The gap between WS-15/F135 class and ADVENT is roughly 20 years if that.
Not an expert but I would expect that with modern methods, computers, facilities etc, that this gap can be reduced by a lot. Not saying that the gap is 5 years but maybe something like 10-15 years (maybe 13?)It would be interesting to see how much of that was real experimentation, development and testing and how much of the 20 year time difference was due to the US procurement system's inefficiencies.
don't know where some of these assumptions are coming from. The 20 year estimate is based on the guesstimated program length and the assumption that ADVENT was started after core development for F135 class engine was completed. I doubt there is much procurement efficiency that hinders the engine development. It would take China roughly about as long as some advantages are enjoyed while drawbacks probably mean more time required e.g. computing being better now but less overall experience designing engines and with the types of materials required perhaps.
So let me get this straight, the ADVENT basically a hybrid bypass engine combines the benefits of low and high bypass ratio correct? If so I guess the izdelie-30 qualifies as it because the earlier engine design was low bypass but stating things like range will be the same but with more thrust means you retain the advantage of a low bypass engine while gaining the advantage of high bypass by putting in more thrust for better super cruise correct?

Forbes is not a trustworthy source. I would rate it just some levels above National Interest.
As for the US Air Force, dont worry. Their programs seem to be going smoothly so far (see NGAD)
I dont trust any western source. Funny fact is that its coming from David Axe.Forbes is not a trustworthy source. I would rate it just some levels above National Interest.

As for NGAD, its going nowhere. Before that, i would be waiting to see how many B21 they can integrate. They talked about some 500+.
