"Mach 30 ‘Tunnel’ Will Put China Decades Ahead In ..." Topic

…Hypersonic Tech Research

"Hypersonic tech could make it possible for super-fast jets to fly anywhere in the world in two hours or less

"There is a Chinese saying, it takes 10 years to sharpen a sword. We have spent 60 years sharpening two swords … and they are the best." — Chinese researcher Han Guilai

Imagine a wind tunnel, capable of simulating flights at Mach 30 — that's 23,000 mph, or, 30 times the speed of sound…"

Sure…….

They can't even build reliable jet fighter engines, but can do this???

One of their jet fighter engines they've tried to reverse engineer has a life of only 30 hours.

Probably not an issue in combat, since it may be shot down in less time than that. It is an issue when you want to train your pilots though, so they don't get shot down so quickly.

Thresher, 30 engines – not even their old reverse engineered turbojets used on warly MiG knock offs had such poor lives – they were 100 MTBO

"Imagine a wind tunnel, capable of simulating flights at Mach 30 "

Now imagine the CCP, who have to steal every design before being able to produce a cheap knock off version, coming up with something like that first…

Heck, even the model in the picture is a copy of a 70s RPG design… I know an S type scout when I see one :-)

"Early revisions of the resulting WS-10 engine have fallen well short of design goals which aimed to match the Su-27's AL-31 engine on thrust output and reliability. Overhauls were required every 30 hours, versus 400 hours for the Russian benchmark".

They only perfected making tips for ballpoint pens in 2017.

The Japs in 1941 wre short sighted with round glasses, only able to do cheap copies and sucessfull as they fought the heirs of the boxers…

…and they lost.

Could be – the US has been operating mach 20-25 hypersonic tests facilities for a number of years. And the Dongfeng missile shown is a hypersonic re-entry vehicle, fired on a depressed trajectory – very clever tech, but not ground-breaking. Why must every announcement from China be done in such a triumphalist way??? Maybe they can just add back in the old-fashioned attacks on the Running Dog Capitalists and all that stuff…

And also, they're planes almost immediately caught fire when hit, fortunately for the US pilots.

Of course, we all "know" and acknowledge that the Chinese J20 stealth fighter is equal to, if not superior to our F22s and F35s, according to Chinese propagandists.

Thresher, thanks for article. The Russians are happy to fill the engibl5ne bays of every Chinese jet so the issue is moot. And given America is going out of its way to irritate Russia insures Chinese supplies.

It should be noted the Chinese do have experience in turbojets and that article is referencing turbofans. Hence my comment about their old MiG-19 having 100 hour MTBO back on early 1970s.

Remember the super sonic Concord? In the business world everything comes down to money. Aviation is expensive. Things tend to de-evolve in the air transportation business. In the 1950's -1960's air travel was glamorous: champagne, lobster, pretty stewardesses. Now passengers are packed in like sardines and airports are the bus terminals of yesteryear.

Military with unlimited budget a different story.

Thanks!

…and they lost.

They lost because they were a third tier industrial power going toe-to-toe with the largest industrial power. It's not that clear cut anymore.

And in some key areas such as processing of rare earth metals used in high end military and civilian technology, China has all the capability and the US none!

[qupte]the Chinese J20 stealth fighter is equal to, if not superior to our F22s and F35s, according to Chinese propagandists.

I suspect the J-20 is a hunk of junk relative an F-22 or F-35 but that's completely irrelevant.

I suspect in the future of warfare we have:

F-22 = King Tiger II (indeed it's reliability is on par)
F-35 = Panther
J-20 = KV-1s

And then the real war winners:

- Cheap drones and long range missiles + electronic warfare + cyber warfare = Sherman/T-34 – no idea who the winner is here.

And regardless of how poor Chinese jets are and how awesome US jets are, it doesn't impact the severe geographical limitations the US has in fighting any war in Taiwan or the first island chains.

In this case the F-22 and F-35 are hamstrung by range and reliance on very non-stealthy tankers mainly from the Eisenhower era.

The US has one other major limitation the Chinese don't. Chinese land bases are in mainland China. Thus any attack on them risks escalating towards a nuclear conflict. US bases in the region are not in mainland USA, they are in South Korea and Japan. Attacks on them may not escalate to a nuclear response so the Chinese may be willing to target them.

Note even in Korean War when US had total nuclear dominance, they still forbade attacks on Chinese targets despite MacArthur's pleas.

@witteridderludo: I see I'm not the only one who spotted the classic 1970s tech.
