Chinese 6th Generation Aircraft News & Discussions

all is speculations, nothing is confirmed so far, with current WS-10/WS-15 onboard on the prototype I have doubt that J-36 cruising speed is above Mach 2, thrust to weight ratio would be quite low with current engines

Yes of course we are speculating as otherwise there would not be much to talk about on a forum!

What is almost certain is that the J-36 will be powered by 3 ACEs and they should in theory allow it to supercruise at maybe Mach 2.5.

As WS-15 has been in serial production for over a year, it is more likely that is the engine being used to power the J-36 as that would allow closer match to final ACE engine.

This is not a place for publishing academic papers; various analyses and speculations are allowed. If you look at this forum as if it's a court case, I think you might be a bit confused about the situation. And among so many speculations and analyses, why are you targeting me specifically? That's quite strange.

I was planning to release some more analysis on the J36 avionics and stealth technology, but the environment here is too poor, so forget it, I'll see about it later.

You have more fun playing by yourselves.

No it is NOT strange, strange is your arrogant behaviour to think to make bolt claims that even contradict what most credible poster on Weibo claim and summarise and when asked for proof or at least an explanation - and a Mach 3+ claim indeed almost demands an explanation - you become rude, insulting and try to turn the fact around as if we have to argue why it makes no sense.

As such, no-one demands to post academic papers if if no-one here would complain, but stating theories and making wild claims as facts and then getting rude is not the way we accept here and if you don't like it then it's your problem.

So, no-one is targeting your specifically, only your behaviour is inparopriate.

No as it depends on cruising altitude.

Climb high enough and the atmosphere gets very thin and so you can cruise very fast without too much air resistance due to lack of air.

Cruising at a higher altitude reduces drag, but the wings lose lift, and engine efficiency suffers. The J-36 intakes don't have variable intakes, at higher speeds the shockwaves will induce a compressor stall. How does cruising at higher altitudes fix these problems? Even if there were variable ramps, cruise still wouldn't be anywhere near mach 4 as the engine will still loses efficiency at those speeds, afterburners help a bit, but theres only so much fuel you can dump into the burner and it's not fuel efficient at all. That is why ramjets are used in missiles that cruise mach 3-4, and turbojets can get UP to mach 3 with variable ramps. The SR-71 famously used a sort of turbo-ramjet to achieve mach 3.2. All the evidence points towards the J-36 having a top speed around mach ~2, not 3-4. Variable geometry ramp intakes are also less stealthy than fixed intakes like both caret and DSI, therefore in order to go faster, the J-36 must compromise range and stealth. Both are not desirable things to lose.

AND not to mention, after a brief discussion with the Chief Designer of the J-36. We basically have confirmation from very credible people in China that the J-36 is not Mach 3 capable and will not use an engine like a RDE or Ramjet. So the physics and the design all lines itself up here. Unless you want to disagree with the actual man who designed the aircraft you can live in fantasy land.

just speculating, China is nowhere near the completion of ACE project, no ground or air testing so far, and how do you know that J-36 is currently using advanced versions of WS-15? As you said STANDARD WS-15's production is just started over a year ago, within such a short time period I have doubts that J-36 is using ADVACE VERSION OF WS-15, most probably J-36 is using STANDARD WS-15,

you're speculating too much bro
 
After unveiling two “new toys” in China, BAE unveils GCAP's latest CGI.
It still seems to have the traditional 5th Gen fighter look.

IMO it is an impressive and really good-looking fighter … but not a true 6th generation IMO

Ironically you won't be seeing people biting each others neck arguing whether it is a sixth gen or not.

This one differs from the black and grey sliver paint one?
When was the sat image being taken?

Allegedly seen om 1st January and indeed it's different!

IMO it's a smaller and slightly different RCS-model turned upside down.
 
I just went to the F-16 forum where they discussed about China's 6th gen, and it seems that some Americans there are really arrogant in overestimating their technology and underestimating China's. Like this quote here from this thread's page : https://www.f-16.net/forum/viewtopic.php?f=78&t=59936&sid=5dc9b452454be82f13733c8e1be3cb9b&start=90


Quoting:
Ricnunes
Elite 5K

"I'm very skeptical about that.
I would say that this aircraft - lets' call it JH-36 - has a RCS similar to a B-2 which is somehow higher than the F-22 (and F-35) but most likely less than the J-20.
This would be in line with the road that the Chinese still have to endure in this "stealth aircraft race" (since the Americans still have decades of head start)."

Quote over and My Opinion :

"Decades of head start" is not a great argument, as sometimes an upstart and fast-learning newcomer can surpass one with a head start too due to various circumstances and multiple variables...(including that the average IQ in China is higher than in America)

Therefore, it is illogical to assume that 6th gen aircraft which is supposed to surpass all 5th gen aircraft in stealth capabilities would have higher RCS than 5th gen like F-22 and J-20...

In my opinion, China's new J-36 definitely has an RCS lower than both F-22 and J-20 if the recent Chinese scientific publications we read about 6th gen jets needing to have "extreme all-aspect stealth" is....

So I assume that the new J-36 will have at minimum 3 times lower than the RCS of an F-22, and at best 5 times lower than the RCS of an F-22, and that the best counter-stealth radars(except quantum radars which have yet to be deployed) can only detect the J-36 if the range is within less than 25-40kms....(which is too late for doing anything as the J-36 would have already fired whatever munition they want at any target from 100kms away)
 
This article also talks about how the J-36 is supposed to be "very stealthy" and can penetrate even the best enemy air defenses and have a "ghost-like presence" in the skies, which definitely seals the deal that it has to be much more stealthier than all 5th gen jets including the overhyped F-22 Raptor, which is somewhat too overestimated by some people in the F-16 forum : https://bulgarianmilitary.com/2024/...tor-calls-it-the-best-6th-generation-jet-yet/
