Chinese team test jet engine ‘able to reach anywhere on Earth within 2 hours’
  • Prototype flown in hypersonic wind tunnel simulating flight conditions at nine times the speed of sound
  • The ‘sodramjet’ engine could offer the biggest hope so far of commercial flight reaching hypersonic speed, the scientists say
Chinese scientists have built what they claim is a revolutionary plane engine for Mach 16 flight. An aircraft powered by the engine could reach anywhere in the world within two hours, they said.

Damn, there's been a lot of breakthrough into scramjet and hypersonics, and it all seem to be greatly accelerated thanks to that hypersonic wind tunnel.

I have heard rumours that the purpose of such research is to develop airbreathing hypersonic intercontinental cruise missiles, to complete nullify any ABM system in development which depend on exoatmospheric interceptors. DF-100 may in fact be a theatre range version of such a weapon.

Perhaps a great hope for commercial hypersonic flights but that would be decades away from getting a sodramjet engine to working well enough for practical purposes which is probably years if not decades away even if the working prototypes are being wind tunnel tested. The Israeli guy's right about hypersonic commercial flights probably not even going to happen soon if ever. Still excellent stuff.

The point of this image is not to show a commerical engine. The point is that they can make a one time engine easier and use it for the military.

Prof Chris Combs, despite being a UTSA Professor, has rather silly ideas about the sodramjet (the point of a 50 millisecond flight is to validate the idea enough to justify building a flyable prototype. One hopes his students have a better grasp of the R&D process and the TRL chart. I suspect that actual flight data wasn't provided in the publication because well, it's classified).

Also, yes there are Mach 16 tunnels in the US, but they aren't big (or have long enough duration) to flight test actual propulsion.

He is right that the sodramjet is a type of shcramjet though.

The best high Mach tunnels are in Russia and now China. The tunnels in Russia can do Mach 20 I think.
The US is hopelessly out of date in infrastructure in all sectors.

Is it a surprise the Russians have the Avangard and Zircon while the US military industrial complex hasn't achieved similar systems yet?

Why do you think the US are now touting "tactical nukes"? They've lost the edge and can't hack the political humiliation of losing a war against China.

Have you ever heard of computer simulation software?
Basically most all designing phase testing is done with software such as Dassault Systemes Simulia ever before leaving the drawing board.
The reason why the US has been able to design and test a 6th generation fighter(within a year) so quickly is because of this kind of technology connected with super computers since the software relies heavily on the computation power.
This trend is the same with commercial automotive industry with initial design concept to proto typing within 18 months.
On the other hand, high mach wind tunnels can only provide mili-second simulations so it is very limited in capacity in testing a design.
That is the very reason why the US has not developed any new physical test facilities except for the final stage testing fascinating the final model to a hyper velocity rocket to see how it respond to the speed comparing it to the simulation.

Chinese are definitely progressing very fast

and the start of this decade has shown that China has mastered quite few niche technological challenges

one of those being advanced turbofan engines for military purpose

we have also seen huge advances in naval marine engines

overall now Chinese have no barriers to truly modernising their military
