Even inlet shape isn't an issue anyone with a decent HPC can design it, it's the materials, communication and fluid dynamics a pain in the ass, Every major army would be fielding stealth aircraft if it only took getting the fuselage shape right
Oh, trust me, they put billions on that inlet design, there are literally thousands of inlet design out there, the whole “aerodynamic doesn’t Matter that much at such speed” thing is the boeiniest Boeing bullshit I’ve heard

A lot actually but my personal favourite would be space accessibility up until now majority of astronauts are former pilots as they have to withstand high G load TBCC would allow us to send a pregnant lady and bring her back without making a mess
Is it valuable for a fighter/interceptor regarding power to weight, you know a fighter-interceptor or strike aircraft traveling at Mach 6 for short time for a dash and the payload itself being HCM so it immediately starts scramjet without rocket booster?

Designing isn't an issue these days it's making one based on that is the real challenge most countries can't even make it work properly in a wind tunnel and I don't know who told you that but aerodynamics absolutely matters at that speed even more so, Atmospheric air starts to behave like water at that point

Northwestern Polytechnical University just completed a test of their Feitian-1 kerosene RBCC engine (煤油燃料火箭冲压组合循环发动机).

Someone please translate.

Or should this belong to the Space thread?

This is such a clever platform, it’s perfect as a foundational test platform for everything to come from the University.

This booster plus HV combination recently did a parachute test to return booster and HV to earth after a successful scramjet test I believe.

This platform starts the test at scramjet speeds, not from 0mph, the first engine part to ignite is the scramjet, not the rocket engine.

Only once the scramjet has fully ignited and been confirmed will the test actually start, and if anything goes wrong up until that point, the test can still be aborted and the entire system recovered. That’s pretty clever.

Interesting idea but releasing a payload at Mach 6 inside the atmosphere is pretty much impossible

I mean the big reveal in that comment for me is the “the aerodynamics are easy the fluid dynamics is a pain in the ass” statement. The aerodynamics *is* the fluid dynamics. Air is a fluid, aerodynamics are a subset of fluid dynamics. The fluid part of the fluid dynamics in question for hypersonic flight is air.

Northwestern Polytechnical University is under sanction by the U.S. It makes their achievement even more amazing.

Chinese university sanctioned by US declares success of hypersonic test flight​


  • Northwestern Polytechnical University team says its combination of rocket and air-breathing engines could exceed Mach 5
  • NPU, which is directly managed by China’s Ministry of Industry and Information Technology, has taken part in the development of many weapons

“The world was so recent that many things lacked names, and in order to indicate them it was necessary to point. ” — García Márquez
This is the current status of hypersonic technology, it’s like cars before model-T, first practical HCM/HGV of course aren’t meaningless, but so far , they didn’t provide any game changing capability in comparison to DF-21D or SR-71.
What matters is who will create the model-T, and that masterpiece, far as I can tell, has to be powered by TBCC/TRRE, scramjet today, can’t fulfill the requirements due to it’s many fundamental flaws, the thrust and TWR is limited by physics.
We are far from there is what I’m trying to say, from my point of view, I’d say China is most likely to reach the goal first to be honest, at least we have a practical idea ,walking the right path at least I believe so.
Americans are developing TBCC too, but I’ve checked their essays, they were on External parallel combined engine with LH2 in 2018 which in no way a right path, so I wouldn’t bet on them.
Russians couldn’t do anything anymore, this is way beyond their Soviet legacy, Zircon is far as they could reach.
Europe? Germans are way ahead of everyone else and based what I’ve read, there’s absolutely no chance they can lead the way.
Japan and Korea are basically non existence, their technology is so backward there’s no point talking about it, they are in the same league with India, they could make their own HCMs in next 5-15 years.
Detonation drive is the future, RDE is just one of many possible solutions , what I’ve posted is another one, but current Scramjet tech? It has no future.

Who's Garcia Marquez and where is this excerpt from? Please link. Thanks.
