As I understand the nose angle is one of the limiting factors on speed in that you dont want the shock wave crossing the skin of your nose cone,

The geometry of the plane suggests a sub 2 mach airframe speed.

Mach limit is a function of altitude and atmospheric pressure. Is this calculation of sweep angle based on near sea level.

We may be able to start with a mach limit assumption and calculate operational altitude of this but none of this is particularly useful since we honestly have little idea what the speed and altitude performance of this fighter is.

Agreed. It is a theater level deep penetration command combat aircraft. It will have a few CCA, or even several waves of CCA at its command. And its ability to take out assets backing enemy's CCA and manned fighter jets like aerial tanker, EWACS, gound based radars or navy fleets etc should not be overlooked.

J36 should be deployed to take out enemy's high value platforms using whatever it can command. And fires its weapon only when necessary, example shooting at an F-35 coming too close to merging point.

And if it can do target correction via data link to antiship ballistic missiles like DF-26, that would be a big plus, but I think I am thinking too far ahead of time.

This is how I think. J36 is the more stealthier, longer range and higher payload version of J20S.

J36 can also command 4-5 loyalman vs only two loyalman for J20s. Everything is one notch up compared to J20s.
Thinking too small IMO. @Biscuits said it right, you can't assume that what anyone else has in mind is what China has in mind.

Why would you need supersonic speed and a huge weapons bay with a mere drone controller that doesn't really shoot its own weapons?

You could just have a minimal weapons bays for self defense only, matching drone speed only kinematics, etc. Anything on a plane is there for a reason. If it does not justify its cost in both money and opportunity it will be cut.

We have a Chinese military expert say that GaO is almost ready and that will give China a generation gap vs APG-85. There is no proof that hypersonic missiles will be used on J-3
The PL-17 when fired from a supercruising J-36 will certainly go past Mach 5. I expect any rocket power weapon that fits the J-36 main weapon bay to be hypersonic by virtue of the speed/energy boost from the launching aircraft.
if you design a new 5th generation aircraft, you can definitely design a larger weapon bay.

Size of IWB by definition is a design requirement of one aircraft, not of all 6th gen aircraft.
Except that there are no 5th gen aircraft in existence are under development that will have weapon bay anywhere close to the J-36's size. So IWB dimension is a true differentiator for generations, like stealth was for 4 vs 5th gen.
Be careful to understand the difference between what J36 requirements are vs 6th gen of another country.
I am predicating that 6th gen requirements for the manned NGAD of the USAF will be very similar to the J-36. We will see who's right.
No, I have been around for a while and it will be best if you keep calm and do a little less hash tagging and flag waving.
Yeah I have been around for a while as well. You are delusional if you think I am the flag waver on this forum.
The UCAVs are unmanned by definition. So I don’t get the pilot part of your response. They are also smaller due to the lower cost nature. They simply do not have the interior space to have same level of electric power generation needed to replace J36.
No, what Yankee meant by his tautological statement is that drone are NOT inherently smaller or lower cost. You have to stop thinking of them as such and recognize that high end capabilities will need large, expensive high end platforms, both manned and unmanned. As least this is the PLAAF thinking according to Shilao & co.
can it perform the task individually? Probably, but why not utilize the surrounding assets?
Because its speed and range means that in many cases it can appear in location where there are few supporting assets around.

Of course and using fighter bomber to describe it is just a misnomer. It’s so much more than that.
So something close in size to this but with more range?

I think something with 1 ws15 or 1 ws19 engine are the most likely configs. Using flywing design and no pilot, you can achieve pretty long range. Maybe they will use engine without afterburners.

UCAVs have to be pretty large to keep up.
This is how I think. J36 is the more stealthier, longer range and higher payload version of J20S.

J36 can also command 4-5 loyalman vs only two loyalman for J20s. Everything is one notch up compared to J20s.
Yes, think about J10b when it first came out and they planned for its electronic architecture with J20 in mind. J20S is that for J36. Same number of operators. Remember, J20S was delayed because they were waiting for certain electrical system tech to become available. It was always designed to conceptually be like an early command & control aircraft up front.

J36 obviously will do it much better.
The PL-17 when fired from a supercruising J-36 will certainly go past Mach 5. I expect any rocket power weapon that fits the J-36 main weapon bay to be hypersonic by virtue of the speed/energy boost from the launching aircraft.
There is no reason for certain weapons to go into hypersonic range because they are not designed to be efficient in that envelope.
Except that there are no 5th gen aircraft in existence are under development that will have weapon bay anywhere close to the J-36's size. So IWB dimension is a true differentiator for generations, like stealth was for 4 vs 5th gen.
That’s because no Air Force has the requirement that China has. Who else is waiting for a near peer conflict in westpac?
I am predicating that 6th gen requirements for the manned NGAD of the USAF will be very similar to the J-36. We will see who's right.
I am predicting it will be very similar too, but that’s because both countries have to fight a high intensity conflict in pacific.
Yeah I have been around for a while as well. You are delusional if you think I am the flag waver on this forum.
You don’t have to change your behavior. If your post cross certain line, it will be deleted.

The drones will definitely be smaller and lower cost than J36. They just won’t be smaller than something like J10. Huge difference.
Because its speed and range means that in many cases it can appear in location where there are few supporting assets around.
Feel free to list a scenario and let’s discuss.

Yankee's latest piece on CHAD:

Apparently he has been lurking here lately and taking notes on what people said:

He likes the warship reference and considers whoever made the above post a "fast thinker" (可见还是有反应足够快的洋人的)

He included the latest update to this meme that added the tricycles for the poor PLAGF?
