Chinese Claim to Have Flown Regeneratively Cooled Scramjet at Hypersonic Speeds in October

China’s success in flying a scramjet-powered hypersonic aircraft, trailing the U.S. by no more than a few years, reveals that its engineers have overcome severe cooling problems first mentioned five years ago. The successful test, announced in October, followed the January 2014 flight of a Chinese hypersonic glider.

The China Society of Aeronautics and Astronautics says the engine of the aircraft, which must have been unmanned and probably quite small, is the world’s first kerosene-burning scramjet with regenerative cooling. This is at odds with the Boeing X-51A WaveRider, in which fuel cooled the engine while being heated to improve combustion, flown in the U.S in 2010 and again in 2013.

The society announced the Chinese success to recognize the achievements of the project leader, Wang Zhenguo. A professor at the National University of Defense Technology, Wang led the research and development team for more than 20 years, from concept to planning and system integration. This involved “development and production in a nationally important project for a certain type of hypersonic aircraft,” the society says. Wang, referred to as the chief designer, was also in charge of flight testing.

As a result, China has become only the second country, behind the U.S., to independently fly such an aircraft, the society says. Chinese media quoted the society as making these statements in a report on its award to Wang.

The confusion comes from the fact the American scramjets heat their fuel, rather than cool the engine. I wonder if this is a translation issue: the engine could heat the fuel through cooling the engine.

Well, if this stands up, then, crap.

The Chinese don't seem to have the Russian disease where they claim things that are not the case.

Eh, China has made claims in the past that didn't stand up, just not as bad as Russia has. Even if they flew it once they have a long long way to go.

The thing is, so do we: our problems are more self inflicted though.

We have the SJX61-2 successfully flying now, but the hypersonic missile is going painfully slow.

Everyone working on it is at about the same place. They're all having problems. Even with missiles.

Well done China. They are only 10 years (+) behind Australia.

Was wondering how the Australian research was going after its successful flights at Woomera to find it shelved.



Australian researchers have mothballed a hypersonic scramjet project after a rocket prematurely plunged into the sea off Norway during a failed test. The University of Queensland (UQ) was leading the project to collect data from the scramjet to test whether the technology could be used for future air and space travel. The three-year project is part of a $14 million program. UQ professor Russell Boyce said in a statement the rocket was launched in ideal conditions at the Andoya Rocket Range in Norway but something went wrong.

Thats late 2013

Ya, no matter what china says they have accomplished, North Korea has accomplished it while the rest of the world was in the stone age. Lol

Ummm, except for all the time, for just about everything. They are no different than Russia, North Korea or Iran in that respect. It is state run media after all.[

I was under the impression we were further along than others and it was more a problem with the material science than anything. And the funding.

Material science has not been a strong point for the Chinese.

Everyone is at about the same point. They're finding different ways around it. We're somewhat ahead, but have run headlong into a nasty brick wall that's going to be difficult to get over.

Have we solved the eight minute barrier yet?

No. No one has to date.

Not funding but government mismanagement,political infighting and general lack of understanding.Our political system is caught in the 1960,s and have very little chance of growing up.

I'm confused as to what the "Eight minute barrier" is?

Did some googling but no luck..

(Basic terms please I never wander round these parts of ats)

So far all x51 waveriders flown have lost contact and/or broke up after around 8-9 minuten of hypersonic flight without any prior notice.

Scream jets have a couple of problems one being heat. Parts wear out very quickly new materials can help with this and like the US they can use the fuel running through the skin if the craft to reduce heat.

However on doing this they also hurt the efficiency of the engine and add more weight to the engine. The problem with this is scream jets don't provide alot of thrust so the more weight the less efficient they are. Through on top if that the drag they create you have to slow down the air entering the jet this creates drag and of course again lowers the thrust you get overall. If the thrust goes below a certain point the plane goes down much like a flame out in conventional craft. The other problem is they don't really start working until March 5 so you need a way to get to that and then the last problem fuel how to get enough for a prolonged flight without adding to much weight. Because again the more weight you add the less thrust the engine will provide.

Without an effective dual purpose engine your stock with rockets to get up to speed.

Don't know why, but reading that made me think of the fictional Zefram Cochrane and the first warp speed test.

Well done to Oz.
But 13 years later and still nothing practical on the horizon for Scramjets?

I openly wonder whether the answer is increased size. As volume cubes in response to increasing dimensions, it gives you much more interior volume with which to soak up that heat, etc. Which seems to me to be a crucial detail when your vehicle has no other way to radiate that heat.

Part of me thinks that hypersonics will work out similarly to LTA craft, where the designs get much more usable as they get bigger, and it's all but impossible to build a functional small LTA craft.

Similarly to LTA craft, it'll also mean that funding and development is this perpetual catch-22 where the small designs that are cheap/easy to build and fund, but show very limited functionality, scare off investors and politicians and make it that much less likely that someone will cough up the money to build something big enough to be really useful.
