Chinese hypersonic research

[Shotgunner51]

Good news!

Incorrect.

The Army’s experimental hypersonic missile just exploded four seconds after takeoff - The Washington Post

How is it incorrect?

I said that US is testing, not commenting on its success.

He is butt hurt indian. But at least India can brag they sent a probe to Mars with NASA's help.

Well, bringing my nationality in, and then bashing it, seems to be the favorite way to avoid reasoning.

Don't know what an useless Indian doing in here!

Then make yourselves informed that this forum is a publicly open one, with no restriction based on Nationality.

And it is a rather weak statement on your intellect, when you can so boldly claim about the "uselessness" of me, when you know nothing about me.

Best thing to do would be to put these HGV warheads (conventional or nuclear payload) on Submarine-launched ballistic missiles.

If they don't know the point of launch, it becomes almost impossible to counter it, not to mention the significant maneuvering of this platform during flight. And the speed which gives the adversary almost no time at all.

We should be able to attack any major warship if it poses a threat to our interests, even if it is halfway across the globe.

We can upgrade our current ICBM/SLBM with the new HGV technology.

And that will make the missiles in our current inventory even more supermaneuverable.

Yes.

What China is testing is not a scramjet, but rather a hypersonic glide vehicle.

There's a difference between a scramjet, and a glide vehicle.

100% correct, hypersonic glide vehicles are essentially ballistic missile warheads that offer increased maneuverability. HGV's are going to be very expensive and not operationally relevant over a sustained conflict. The Wu-14 is an HGV as well as US projects such as the HTV Falcon and Advanced Hypersonic Weapon. The AHW was successfully tested in 2011, but in 2014 failed due to an anomaly in the booster section. There were no problems found in the glide vehicle itself.

The other type of hypersonic weapons are endo-atmospheric air breathing scramjets. These will eventually lead to hypersonic cruise missiles. They will be less expensive than HGV's and more operationally relevant in conflicts. The US successfully tested the X-51 Waverider scramjet in 2013.

The US has at least 4-5 hypersonic projects in both HGV's and scramjets under development, and are close to deploying them.

The US is already developing systems to counter HGV's such as THAAD-ER.

Well done China.

China too has multiple hypersonic projects under development and also developing counter weapons like HQ-29.

China is also developing directed energy weapons and railguns. You pretend as if the US is the only country developing these weapons. Nothing special in the US.

Fairly speaking，as the biggest and the most evil power，USA INDEED was the first one to mention one hour globe attack system，that idea forced China and Russia to follow its pace，USA thought its technology the NO.1 and can easily leave us far behind，at that time，all the countries including us and Russia have to obey its orders. But today，the HGV of USA tests fail almost everytime ，I am confident we will deploy such kind of weapon first. Our DF21D missles can attack aircarriers around us now，the hypersonic gilde weapon with our Beidou globle position system can attack the Aircarriers all around the world in the future，we will defend the world peace for the mankind.
The happiest thing is：we have very competitive military insitutes and very bright future，many weapon showed up last decade specially after 2010 have proved it. After decades of shortage of military fund，our country begin to invest military institutes less than decade and the fund is still much much less than USA，but the outputs are amazing，our whole military technology system is almost at the same level with USA，USA is still in front of us but it can not scare or shock us with its muscles，the game competition will be a good show as we will invest more and more in military today.

The video has stirred many people. In my analysis, I conclude it's a hypersonic air-to-air missile.

From the opening scene, we seen a long horizontal contrail that extends tens of miles into the distance. It should be obvious to you the hypersonic missile is not that far above the ground/city and flying horizontally. If the missile had been flying vertically, the camera would have to pan up dramatically (like a Shenzhou flight). Instead, the horizon line in the video is relatively constant.

The hypersonic air-to-air missile flight shares the same "bow shock" as a hypersonic ballistic missile/rocket (see Shenzhou 9 flight). However, in the video, the hypersonic air-to-air missile has a blindingly white nose cone. This is a result of traveling hypersonically in dense low-altitude atmosphere. You never see a blindingly white Shenzhou nose cone, because it travels hypersonically through the rarefied high-altitude atmosphere.

The PLA has to conduct its hypersonic air-to-air missile test over continental China, because the U.S. has many sensors on ships waiting offshore to monitor a seaborne test. No one wants to share their test flight data with the other side.

The PLA probably intentionally conducted the test on a day with high moisture level to create an easily discernible bow-shock trail for later analysis.

The timing of the test during twilight was also probably intentional to create a high-contrast video. The video of the hypersonic test flight can be analyzed through spectroscopy to determine the temperature of the hypersonic air-to-air missile's nose cone.

After 30 seconds into the video, the bow-shock briefly stops and a second bow-shock is seen. This looks like the missile slowed down and then picked up speed again. Did the PLA intentionally throttle the engine momentarily as part of the test?

I believe the Chinese air-to-air missile is hypersonic, because I've never seen a bow shock this large. Supersonic aircraft or missiles create very small bow shocks and moisture condensation. Ramjets "as a class work most efficiently at speeds around Mach 3." I think China was testing a higher-speed hypersonic scramjet engine.

Thanks for sharing. I can ASSURE you, the thing moving, wasn't moving beyond Mach 1, at times may be two, when you saw the Sonic splash / bow effect expanding. That can happen due to many reasons, not because something was Hypersonic. Your camera wouldn't correctly capture the Hypersonic object as the speed is simply much much faster than this.

If I was to guess, this wasn't a missile. This was probably a large body aircraft under experiment. Chinese area 51?

 

[cirr]

interesting。

A-2-A missile powered by a scramjet？

If anyone, this guy from the NUST should know.

[Goenitz]

correct me if i am wrong...
shock waves are a "transitions phenomena" ... not a continuous one... bow shock depends on shape rather than speed... like nose of missile/space shuttle forms that...
plus i think shock waves are formed just near Mach 1 and not on subsequent interval like 2, 3,4,5 etc.. or is it possible that a Mach 2 object downstream air can form a shock when it reaches Mach 1?
Howver i think, this very HUGE trail is just condensation due to rapid expansion/compression...

 

[Martian2]

A Mach 1 nose cone does not glow. Neither does a Mach 3 YJ-18 warhead, which is a video that I had previously posted.

In the video (see post #1), the nose cone is at least 1,200 degrees Celsius (or 2,192 degrees Fahrenheit). It's glowing blazing white. It's a hypersonic missile.

----------

Watch the re-entry of real hypersonic Mach-23 MIRVs at 2:07 to 2:11. They are also blazing white.

 

[Luca1]

Different platforms.

What China is testing is a glide vehicle, which will have to be carried upto the edge of atmosphere by a ballistic missile.

What US is testing is a scramjet, an air breathing missile which is much more flexible in its potential use.

U.S. Is testing both.

 

[XiaoYaoZi Backup]

U.S. Is testing both.

We also testing both.

A Mach 1 nose cone does not glow

due to extreme height and condensation of gases, it may be appearing bright from rest of the sky.. as its still twilight..
like far cloud at sun set region... of course glowing occur >3 when frictions is higher enogh.
