Oh yes, they are great for making flight sim stuff ( I wish my soldering skills were up to snuff ).
But copying others IP and selling it more cheaply is not a good example of "innovation" unless you are Microsoft.
IMHO the only innovation that has come out of China are drones, specifically from DJI.
Their drone technology is unrivaled and they are years ahead of everyone else.
I think DJI succeeded despite coming from the CCP, probably because the all knowing central planners are too stupid to realize what DJI did until they dominated the market, and they have tried to interfere with them ever since.
“I look at all the stolen tech, liners, flaps and seals on the nozzle. Chem milled titanium engine casing. Like the poster above; where did they get this tech?”
That is a Pratt & Whitney F-22 engine.
SiAlON ceramic.
Loral and Bernard Schwartz (and Bill Clinton).

“at that speed the friction generated temperature would be about 15000K”
Not at 18 miles high.
Well I just told Copilot to caculate it based on standard international flight altitudes... those are 5 1/2-7 1/2 miles up
KH/H = Kissing Men per hour?!
That’s a lot of men!
“Can you imagine the g’s in a small 2 minute turn at speed?”
How many?
10,000 spies in all of the major colleges and research centers in USA for thirty years. Everything they have was stolen, and never has paid a dime in patent infringements.
Plus our manufacturing was shipped over there along with technology. Traitors all.
War is inevitable.

Again, > 18 miles.
By theft.
Who did they steal that technology from?
No blacks to hold them back
“ They are smart people who know how to do advanced math.”
How do they plan on keeping passengers and the pilots from blacking out? If the plane has to turn, wouldn’t that pull G’s?
What are they going to make the airframe out of? The SR71 at mach5 could barely handle the heat.
“ Oh sure...Super/ Hypersonic over ANY major city or towns? IIRC this was the HUGE concorde problem. Sure London to NY is 2 hrs.. Then it still takes 3 to get from NY to Chi.. Do we really need hypersonic Temu deliveries?”
Concorde flew over my house every Sunday at 2:00 pm for years…No sonic boom. That would have occurred over the Atlantic Ocean I believe, not when it was closing in on landing at IAD.
The SR-71 outside is titanium.......
Like all other supersonic craft, they do slow down a great deal to land.
Hmmm...
Reminds me of when Daenerys Targaryen stepped out of the fire holding her three dragons...
Big trouble coming?
I doubt that this engine, real or not, is being developed for commercial travel, or even cargo.
As one poster said, that speed is just a tad short of what’s necessary for Low Earth Orbit.
Put a couple of these on a spacecraft and you can take off and land on Earth after visiting a space station. They have one.......................
