Chengdu next gen combat aircraft (?J-36) thread

[LanceD23]

From chinese side, its widely believed that J36 is spec-ed at 30,000 meters and Mach 3.

for various applications, including radar-evasion. The patented invention is a multi-band stealth metamaterial assembly that is bullet-proof and light-weight.

The invention relates to the technical field of functional composite materials, in particular to a lightweight, low-thickness, long-term and reliable multiband radar stealth and bulletproof integrated metamaterial which comprises a ceramic layer, an ultra-high molecular weight polyethylene fiber composite material bulletproof layer, a graphene metamaterial filtering layer, an ultra-high molecular weight polyethylene fiber composite material loss layer and a carbon fiber reflecting layer which are sequentially stacked. According to the invention, two layers of ultra-high molecular weight polyethylene fiber resin composite materials are used as loss layers, the circuit resonance of the graphene metamaterial filter layer is utilized to generate pass bands and stop bands, the working conditions of the ultra-high molecular weight polyethylene fiber resin composite material layers in different radar wave bands are controlled, and a structure capable of generating lambda/4 resonance at low frequency and high frequency simultaneously is further established, so that a wider absorption frequency band is realized in a plurality of wave bands, and the adaptability of the prepared radar stealth bulletproof integrated fiber reinforced resin composite metamaterial under radar detection in different wave bands is greatly expanded.

Guys, let's try to stay on topic here, which is J-36.

It seems USAF has reached the bargaining stage w.r.t. Chinese 6th gen aircraft.

The US and China are locked in a “race” to field the next generation of airpower — and there’s no guarantee America will cross the finish line first, according to the Air Force’s outgoing acquisition executive. “They could beat us to the punch,” Andrew Hunter told Breaking Defense in an interview at the Pentagon. “It’s fair to say we pay a lot of attention to what the Chinese are doing. And so, not everything that becomes public is a shock,” Hunter said. “But having said that, their pace is incredibly fast.”

Hunter highlighted the Air Force’s “technical advantage,” reasoning that those features “are meaningful and that our system is producing good materiel” even if they may not always come to fruition as quickly as desired. “So [the] IOC date on something, they may well beat us on that. I think we’ll have the better capability, but we certainly have no time to lose,” he said.

which aired earlier today.

“The Air Force [originally] wrote requirements for an aircraft that is essentially an F-22 replacement. And for the last few years, that’s what we’ve been working on,” Kendall said. “We’re now at the point where we commit to going forward, to finish design, and go into production of that, or not. And this is really the most important milestone for almost any program.”

He specifically drew a contrast between that, and other conceptual aircraft which controlled CCAs or emphasized strike missions.

“The alternatives to the F-22 replacement concept include something that looks more like an F-35 follow-on,” which would be “something that’s much less expensive, something that’s a multi-role aircraft that is designed to be a manager of CCAs and designed more for that role,” the Air Force’s top civilian added. “And then there was another option we thought about, which is reliance more on long-range strike.”

Now there's obviously lots of details and specifics he didn't explain, but if USAF is truly looking at 6th-gen aircraft from such a limited perspective as "super F-22 or super F-35," then that is a very bad sign for them. Of course it's dangerous to extrapolate too far from one interview, but if the highest levels of USAF leadership are genuinely thinking that way, then the awful takes which were memed as simple copium might actually be a sign of a far deeper and more fundamental shortcoming. Something that loses wars, not just online arguments.

Looking forward to moving to stage 3.

Stage 1: Nothing's going to happen.
Stage 2: Something may be going to happen but we should do nothing about it.
Stage 3: Maybe we should do something about it, but there's nothing we can do.
Stage 4: Maybe there was something we could've done, but it's too late now.

A question: J-36's EW and radar/sensor capabilities have been widely discussed and emphasized. But wouldn't these make any plane very detectable and contradict its stealth capabilities?

AESA radars can be very hard to detect, especially for older fighter jets and small land mobile EW equipment. Bigger and newer equipment do better. Networking, passive sensors and directional data-links are important for VLO aircraft to remain undetected.

If applied to aircraft skin, does it negate all AAMs with proximity fuse? Ceramic as top layer is also high-speed friendly.

Stage 3 is the last stage.

Doesn't matter if it ain't gonna get produced in the first place anyway.

With how things are heading, US is basically headed towards low intensity civil war (basically 'failed state's), and it ain't gonna be finishing bigger industrial projects in the next 10-20 years (as in projects planned to start mass production after 2030s).
