Chinese Hypersonic Developments (HGVs/HCMs)

I agree. China actually has hypersonic wind tunnels that no one else, not even the US, has. These wind tunnels are what enable China to make huge progress in hypersonic researches. Whereas China can do most of the trial-and-error on the ground, other countries have to do most of those trials in the air.

Aughh, forerunner of avionics already adopted computer simulation and had done away with physical tests for modeling a long time ago. These days you utilize super computers and analyze wind sheers in millimeter grids which cannot be done with actual physical tests.

Avionics is generally less demanding on material properties ;).

For what it's worth, I think supercomputers will help a lot more with scramjets than with gas turbines. Moving parts tend to increase the demands on material properties and complicate testing and design, which then brings in greater variability and randomness.

I guess you haven't heard of Computer Aided Engineering(CAE) which simulates component under stress based on what kind of material those components are made of.

I have, but a simulation is still a simulation, and from what I know you can't synthesize an entirely new material and reliably test its applications in an all simulation process. You can synthesize a new material, reproduce it physically, study it, then enter its material properties into a separate simulation, but there are still gaps. That said I didn't say that supercomputing doesn't help at all. It's still tremendous in exploration and research, even with the need to replicate results physically. The real bottleneck is in deploying and producing the technology (especially when they involve new materials), and I think that's going to vary most based on the technology.

Indeed, Talk is cheap.

It's going to hard to counter these points because your "unbiased" e-father, Jeff Head, isn't here to "moderate™" (AKA censor/delete my facts or what he refers to as "biased and ideological posts") while a gentleman of your stature delivers more racist feelings from his glorious American Exceptionalism™ upbringing.

Lighten up though. This nightmare of logic and facts pile driving your face into the concrete of reality will end when daddeee comes back to save you with suspensions and bans.

Since Blackstone's posts rarely get moderated like mine, I'd like us to all learn how to construct fact-based comments without resorting to "racism or ideologies". Here are some examples from Dr Admiral Viceroy Commander Blackstone

If China's scramjet engine advancement is anything like its glorious turbofan development, then we might see some good results on Mao's 150th Birthday.

Talk is cheap, just like there were so much early talk about WS-10 "successes." When it comes to Chinese engine technology advancements, it's *buyers beware*.

True, but the same SOEs. I mean what would you expect to see first, WS-15s on J-20s, or the Second Coming? *I vote the latter.*

While what happened in the past doesn't mean the same things will happen in the future, but demonstrated incompetence tends to color future prospects, until properly dispelled. Wouldn't you agree?

So please guys, don't make the same mistakes as me by quoting from the news agencies, acclaimed military aircraft designers, the World Health Organization, and especially not manufacturer's themselves.

That's biased and ideological.
