YAWN ,LOL

[shanover]

From rice farming to hypersonic propulsion. How did the Chicoms do that?

[butlerweave]

How many millions of gallons of fuel per second ? LOL

[E. Pluribus Unum]

20,000 km/hr = 12,427.4 mph = Mach 16

Detonation hypersonic engine - like the one we were flight testing a couple decades ago?

China unveils a LOT of stuff, but... how about flying one?

[broken_clock]

I look at all the stolen tech, liners, flaps and seals on the nozzle. Chem milled titanium engine casing. Like the poster above; where did they get this tech?

Will passengers have to get a pre-flight physical before pulling 9 G’s

Per Google:

At Mach 7, the G-forces experienced by an object can be up to 9 G1. Fighter pilots can withstand up to about 9 G for a second or two, but sustained G-forces of even 6 G would be fatal2. Astronauts endure around 3 G on lift-off2.

But first, it’ll crash into a Chinese school a bunch of times.

at that speed the friction generated temperature would be about 15000K

Hypersonic vehicles like reentry capsules or experimental aircraft (e.g. NASA’s X-43) experience surface temps of 1,500–3,000 K.

A commercial aircraft (if it existed at this speed) would likely use ablative shielding or regenerative cooling to keep skin temps in the 1,000–2,500 K range.

Those temps are still above Aluminium melting temp of ~933K

[Lazamataz]

Not sure what the airframe would be made of. It would melt to slag from the friction.

Like the Concorde that went before it, it will be the elite’s toy. It won’t be practical for the same reasons the Concorde was scrapped.

Nothing to get excited about.

From the end of the article:

Despite its potential, significant engineering challenges must be resolved before hypersonic travel becomes a practical reality.

Extreme heat and pressure at Mach 16 require advanced thermal protection systems to prevent aircraft from breaking apart.

Materials capable of withstanding these conditions must be developed,

and cooling mechanisms must be perfected to ensure structural integrity during flight.

Another major hurdle is stability and control. Researchers must refine the technology further to ensure that hypersonic engines remain stable across various speed ranges.

developing cost-effective aircraft that can safely operate at these speeds remains a significant challenge.

If the technology proves too expensive, commercial adoption could be delayed for decades.

That is 3.4 miles per second. At 4.7 miles per second you are moving fast enough for low Earth orbit.

[READINABLUESTATE]

Mach. 16.1969239

[PGR88]

little is known about the engine beyond a blueprint published in the peer-reviewed journal Chinese Journal of Propulsion Technology in December SCMP reports.

This is from the linked article

It could very well be "vaporware."

China and the USA are similar in that researchers, businesses, tech companies, etc... all are tempted to put out exciting press-releases, with only vague ideas behind them, to attract government funding or investment capital.

[Yo-Yo]

Tom Cruise has been there, done that.

[Leaning Right]

I can just imagine the global warming that would spew out of those huge engines.

Someone should contact Greta Thunberg before this thing gets out of hand.

“Could”

It’s leftist media.

Writing real articles about fake, projected possibilities.

[Mariner]

Just checking in to see how many believe this...
