I see a lot nice CGI images in videos on YouTube. Does anyone have the pics?
Funny how I coming across claims what a 6th Gen is and China seems to be meeting those requirements but then they question if it really is. They say stuff like NGAD is going to be bigger than normal but then they says China’s is big in context of a negative. They say stuff like China’s doesn’t have AI but how do they know just by looking at it? It’s supposed to have joint strike capabilities like the F-35 but it in itself doesn’t have that fully like they advertised from the beginning. Where’s that fancy sci-fi helmet? Last I heard they’re still developing it.
Well, it says "afterburning turbojet." So yes, it's not a turbofan per se, but I doubt even a turbojet or most conventional gas turbine engines can operate that those speeds and altitude effectively.
A more considered write-up from Bill Sweetman. He seems to be impressed:
"As for the need for maneuverability by a supersonic stealth aircraft packing a heavy weapon load and long-range sensors, the reader is referred to the classic movie short, .
We will learn more about the J-36 as it follows the pattern of the J-20 through a pre-production and service test phase. There are other puzzles about the design: apparently large electro-optical sensor windows on either side of the nose, and a dark-tinted canopy that wouldn’t be road-legal in many US states. But one thing can be said firmly: those who accuse Chengdu chief engineer Yang Wei and other Chinese designers of being copyists need to take a seat."

In that video, many of the CGI pics and clips are of fanmade aircraft which are not representative of either J-36 or the SAC jet. Some of the other pics are CGIs by industry or thinktanks for NGAD.
It's better to ignore those sort of CGIs, they have no bearing or relation to the real airframes we've seen.
RIM-174 and it's AA derivative AIM-174B are listed as 110k and 100k feet. I'm not certain about the latter.
Older AIM-54 is listed at 103k feet.
They are still reeling from the haze of approving that preposterous frigate deal costing $5.6 billion / ship, for a total of 15 ships @ ~$85 billion.

Thank you. The following paragraph hit the main point I had been wondering. What if all three engines do not have afterburners at all. WS-15 is about 100kN dry, so three of them produce 30 ton force without afterburners.
"Three engines in the thrust class of 22,000 lb (10,000kg or 100-kilonewtons) should be enough to make the J-36 a supercruiser—an aircraft that can fly supersonically without using fuel-guzzling afterburning. Its sweep angles point to doing this at Mach 1.8 to Mach 2.0 (1900km/h to 2200km/h, depending on altitude)."
afterburning turbojet is the exact engine used by historical Mach 3 aircraft with 1958 technology. With current materials and computational fluid dynamics I think this can be greatly improved.
Ain't the J58 combined cycled though? That's not a "traditional gas turbine engine" by any means.
Sorry for getting your hopes up yall. I refined my nose calculations with a new 3d model given the blurry side photo we've newly got and it looks like ideally only a ~1.0m^2 radar would fit. Given any module density, take this as you will.
Using my previous calculations, this brings the module count down to a more conservative ~4000. I will continue updating as new photos come out.
PS: I know the chine has not being properly modeled, this doesn't affect the nose structure much.
I'm also hopeful in getting a fluid simulation done too, not that it affects the radar or anything but I'm interested in if I could get a rough coefficient of drag for fun.
