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

[E100]

tbf they are at least higher quality than reddit. No "temu" type comments and mostly analysis. However some of their analysis are straight up... yeah... The typical denial of Chinese air superiority fighter, and the "I don't know what that plane is nor what it's capable of but I know damn sure that F-22 is stealthier/better" assumptions. There's this one particular user that just won't admit that J-36 is meant primarily for A2A despite other users disagreeing, and his one and only argument is that it's big and keeps talking about its wheels. It's such a weird hill to die on...

And as objective as SDF is, it's still inherently biased towards the PLA. I want to see objective discussions from "the other side" as well so I do look for USAF-centered forums.

Mate. Reddit is a pretty low bar for anything really. Stumbling over that is no accomplishment.

High speed ejection, low speed ejection, the middle engine could be running at 100% power. it will not suck the pilot inside. This is a complete non-issue, brought up by amateurs. An ejection seat will easily clear the safe distance within time, you can even do the math yourself.

If you don't believe so, take a look at the F-107 prototype, the intake is nearly straight above the cockpit, yet ejection was still safe in the sense where the pilot won't be sucked into the intake. Worrying about ejection issue on the J-36 is nonsense. Do you really think the engineers didn't think of it before you did?

That point is raised by someone who learnt physics by watching looney tunes

Regarding the dorsal inlet being bad for ejecting... What situation where you would eject while the engine was running? You're ejecting because most likely your engine is not working so no worry about being sucked into your aircraft engine or the aircraft is breaking apart midair. You're most likely already dead or the nose/cockpit has separated away from the inlet.

That's not why nor how you should ever design a safety system. Why would you assume the aircraft is obliterated in order to eject? There could be a flight control malfunction, where in a unstable tailless aircraft, recovery could be impossible. See the B-2 spirit crash, it was on takeoff, the engines were likely at 100% power, there was a sensor malfunction that caused an inability to control the aircraft, the pilots had to eject. There are dozens of situations where you would need to eject while the whole entire aircraft is completely intact..

Why? Do you think China forgot to think about that when designing the aircraft to have a dorsal inlet...? The reason why they included it because they didn't see in most scenarios that the pilot would get sucked into the inlet.

what's the current consensus on the top and cruising speed? Folks over at F-16.net are convinced that it's a bomber incapable of mach 2 even with afterburners

Those folks are either still burrowing their heads in the sand or just straight up idiots. Simple as that.

Indeed ... and we do not constantly need to discuss any stupid claim posted in the www anywhere. That's like trying to feed a dead horse.

Furthermore top speed is not really that important a measure, Mig-31 is very fast but I don't really think anybody considers it way more capable than say F-35 which is significantly slower. Indeed F-35 can't do mach 2 and it's pretty clearly not a bomber so the criteria is off to begin with.

Offtop, but F-35 is very specifically a joint strike fighter.
Which is a fancier term for light bomber.
It is multipurpose and very capable, but saying it isn't a bomber is outright wrong.

It's in fact quite clear even now, that J-36 is a far more fighter-centric design, multirole or no.

idk where is this "pilots sucked into inlet" talk coming from, I though ppl are relatively well educated over here....ok here's some manslainin:

1) Inlet does not "suck air", at zero speed they does but at cruising speed they don't need to "suck air" as much as just let air ram into the inlet due to the airflow, at even higher speed the inlet sometime actually has to restrict the amount of air going in by bleeding air out. So the mental picture of inlet sucking ppl in need to go

2) Things has momentum, an ejection seat coming out at high speed does decelerate due to incoming airflow but it is not decelerating that fast. For example F-16 designer don't need to worry about ejection seat hitting the vertical tail, why? Because there is this thing called momentum

3) Pilots don't eject at high speed period
