-It costed 4.6 billion RMB to build, which is still less than an equivalent facility would have costed outside China.

The interview says 4600万元, which is 4600 x 10,000元, which is ¥46 million, not 4.6 billion.

Really? How much higher? Is there a creditable source for the claim?

Read some of the comments in this thread, other members have already stated the capabilities of the 8FT HTT compared to the JF12.

NASA's website states that the 8FT HTT can handle speeds up to Mach 7 and temperatures up to 2000 degrees Celsius. Terran already posted this in the previous page.

An interview with researchers working on the JF12 reviewed that it can handle speeds up to Mach 9 and temperatures up to 3500 degrees Celsius; a whole two Mach numbers and 1500 kelvins higher than the HTT. I don't know how you missed no_name's post on this either.

A couple points here 1) who says I has to be powered? Or that said power has to be air breathing?
Remember the Hypersonic guide vehicle tests we heard about what Las year?.
2) the PRC have no doubt been working on this since a US M37 drone crashed in the 60s. But they still have issues with alloys and materials in There engines. I don't think they could be to far ahead but then again I doubt they are far behind either.
Remember Lockheed Martin recently launched a offer to the USAF of the SR73 concept.

not sure if you are referring to the link by "GreenestGDP". I have read it. It specifically said two things.

First is "Hypersonic Scramjet Engine".
Second is "Hypersonic Flying Vehicle", one of the test objectives of the Vehicle is to test the design method of the "Hypersonic Scramjet Engine".

As a scramjet, it has to be air-breathing. Since the engine was part of the vehicle flight test, the vehicle has to be powered, at least partially during some stage in the flight, or could even be the whole flight, the link didn't go into detail though.

The vehicle is not related to the glider if you mean by "Hypersonic guide vehicle".

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*.

https://www.sinodefenceforum.com/chinese-hypersonic-projects-research.t7872/page-15#post-367036
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.

apperantly, you are not one of "us".

, that's why.

My mistake, 46 million RMB then, which is a lot lot more cheaper. Especially if you look at the usual size of the facility needed.

A very good investment too, especially if you consider the fact that modern air platforms could easily costs tens if not hundreds of millions each.

It's interesting that CSAA website is allowed to talk about the scramjet, and still stay up, unlike that CNAA report about the Mach 4+ UAV.

The Chinese Society of Aeronautics and Astronautics seems like a credible enough organization to vouch for the existence and successful test flights of the Chinese scramjet. I'm sold.

They edited the scarmjet award to make it less descriptive! Profesor Wang the third guy before the bottom, in the green uniform (Colonel?).

Must have said to much. But the problem with retro-censorship is that the Internet is forever...

Skywatcher,

Was the flight test of the scramjet piloted in situ?

You mean the CNAA article? I think that Professor Wang's scramjet is a testbed like the X-51.

Henri K thinks that was a UAV, and I'm inclined to agree.

1m hypersonic wind tunnel was completed in 1997 and was upgraded in 2002 and 2012, which was composed by two branches: One ranges from Mach 4 to Mach 8, and another ranges between Mach 9 and Mach 10.

Aerodynamic tests could be conducted for various purposes in different methods: aerodynamic force test, aerothermodynamics test, aerodynamic configuration test, stage separation test, RCS test, and inlet aerodynamic characteristic of ramjet and scramjet.

The sub-systems and components of the tunnel include: high-pressure air supply system, air heater, settling chamber, nozzles ranges from Mach 4 to Mach 10, test section, model AOA system, supersonic diffusers, 4000m3 vacuum system, control system, and data acquisition system, etc.

The high-frequency plasma wind tunnel is the high enthalpy test facilities which can heat up gases by using high frequency induction. There are some capabilities such as pure flow-field, long-time running, good simulated abilities and high efficiency etc. The wind tunnel is used to carry out researches of thermal-protective material performances and aerodynamic physics study
