Nice Work by John Fryer :

This is the Bing translation of Sinowarrior's Reply # 39, above:

Wang zhenguo, national defense science and Technology University professors, experts in the field of hypersonic propulsion technology.

Under the State 863 Program, national major projects XX works of a number of major research projects, in supersonic combustion Ramjet engine and ground test, flight test technology for groundbreaking research, achieving the technology leap. First, a proposal, developed China's first regeneratively cooled scramjet engine to reach United States equal level of scramjet combustion in supersonic flow, ignition and efficient combustion and thermal protection is extremely difficult, enormous technical challenges.

United States after more than 60 years until 2013, was not able to break through the key technology. Led the team from the beginning research on supersonic combustion mechanism, after nearly 20 years of exploration, breaking all of the key technology, developed the world's first aviation kerosene regeneratively cooled scramjet (United States X-51A engine uses the special endothermic hydrocarbon fuel), long Cheng Re test evaluation.

Successful development of the engine, which have the ability to independently develop scramjet.

1999 national science and technology progress second class Prize 1 (3rd), 2012 and 2014 by military scientific and technological progress award 1 (1th). Second, overall design, developed a large continuous Hypersonic propulsion wind tunnel, solve the restriction of scramjet technology-a key issue for the development of large continuous Hypersonic propulsion wind tunnel simulation of altitude, high-speed flight conditions was the introduction of supersonic combustion Ramjet engine and Hypersonic test device for the key.

Lead the team to break through the large flow of air heaters and large Active ejection system, two global technical challenge, successfully developed the first large continuous Hypersonic propulsion wind tunnel, building a series of hypersonic propulsion wind tunnel, scramjet engine testing capacity in China reached the international advanced level.

Using the above technologies, developed China's first set alternate pressure recovery system for the aviation Division of hospitals have developed a national major projects the main test system of large air heaters, space technology Institute developed China's first large ejector in Active ejection altitude simulation test-bed system.

In 2009 and 2012 the State technology invention award 1 (1th). Third, the successful development of XX Hypersonic, the successful completion of flight tests, reached world advanced level independent flight testing aimed at real flight conditions verification of hypersonic, scramjet engine design and ground testing method is the only way to conquer Hypersonic Technology, technology is extremely difficult. World United States implement autonomous flight test of 10 times in recent years, 6 of them failed.

As Commander and Chief Architect, led the team for more than 10 years, from concept, design to systems integration, the successful development of national major projects XX Hypersonic and completed flight testing, which became the United States second achieve supersonic combustion Ramjet-powered Hypersonic Flight State. 2014 second prize of national science and technology progress 1 (1th).

Peace,

Get ready, to use the word < EASY > more and more often, instead of < hard >

IMHO, here are my own observations:


#1) There is a reason why HPC ( = High Performance Computing ) Supercomputer is called progressive--force--multiplier for technological breakthrough.

And, China HPC Supercomputer ( made by Wuhan NUDT ) has been the fastest machine by far on Earth for more than 2 years running.

There are the fastest because of their TH-Express 2 Interconnect.
Just to inform you, ... ... in case somebody is jumping the gun and says TH-E 2 was stolen from US.
US does not have an Interconnect anywhere close to TH-E 2 performance.

According to NUDT, Tianhe-2 would have been used for simulation, analysis, and government security applications, such as WS-15, Scramjet Hypersonic engine, and so on ... ...

#2) Global Industrial Revolution #4 is happening quietly in the background right now.
One of the progressive--force--multiplier for technological breakthrough is ( 3D Printing ).

Why ?

Because using 3DP processes, the product development cycle is way much shorter.
3DP processes can dramatically shave the development time by 90% or even more depend upon one's creativity.

3DP processes also allow the creation of complex geometrical end-use product that can not be manufactured before, even using the best CNC machine.

For example: interweaving 7 kind of metal alloy to create hyperthermal engine blade
and shift the engine blade center of gravity by using inner fill structure of various density, and yet without sacrificing the integrity of the engine blade.

3) Using IoT and M2M environment to monitor the Scramjet engine performance while testing and experimenting.


Now, please do not ask me to explain those 3 factors above further,
because I am not an expert.
Please feel free to correct me if I am wrong.

Supercomputing is immensely helpful, but it is not magic, and China isn't exclusive or special in benefiting from it. Furthermore, some kinds of technologies will benefit more from it than others. The Tianhe may be a powerful supercomputer, but it's still just one supercomputer.

At the end of the day, what supercomputers help most with is researching and honing complex concepts. You still have to do physical testing and develop physical processes to come up with a technology, and once you've validated a concept or replicated it physically, you still need to figure out a way to manufacture and scale it. Saying that we should expect China to deploy some kind of new technology because it was researched using a supercomputer and physically replicated in lab conditions is like saying we should be expecting to use carbon nanotubes as transistor material in the next year. Not realistic.

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.

Scramjet has no moving parts. Scamjet is a topic in the larger scope of hypersonic research, and we can see China making huge stride in this area in recent years. Also, the US doesn't have a huge lead in this area to begin with, as opposed to other technologies such as gas turbines and nuclear reactors. Lastly, given how similar articles about ASBM surfaced back in 2010, and that they were proven as true, I will say the article about scramjet is quite believable.
