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

Hi,
I have come across a post or probably a video on YouTube that a IRAQI
mig 25 out run American AMRAAM while in a fight during desert storm
if it’s true, how come because of shorter range missile or speed of MIG
thank you

Unless they have differential thrust control, it cannot accurately represent yaw stability.

Just like looking at a tank without differential drive, someone who didn't know would be confused by how it turns despite the tracks both being rigidly forward facing.

differential thrust control? Isn't that way less effective than horizontal TVC? Since you can never have 100% thrust while turning and the engines aren't that far apart

Sounds implausible. The AIM-120 did not enter USAF or USN service until after Operation Desert Storm.

There was a case of a Russian SU-34 fighter bomber out run 3 patriot missiles over Ukraine air space several months ago. It shows if you can detect the missiles at a distance, you can out run it.

J36 's superior computational power, sensor and speed should have advantage in defeating current generation of AAM and SAM.

not sure if this belongs here but it's pretty interesting

but yea, they better put some horizontal TVC on this thing to control yaw

Is this guy trolling? Multiple vertical winglets, only two flaps, no split rudders. And he calls it J-36?

Doesn't that depend on magnitude of the yaw instability? If you use differential thrust for correcting yaw instability (not maneuvering) you don't need to move any control surfaces at all. Motion of a control surface could cause an RCS increase.

If you need a huge maneuver though you probably are in combat and at that point just use control surfaces.

Will the dorsal intake pose a threat to the pilot(s) if they are ejecting from the aircraft?

Differential thrust control bandwidth is too low for maneuvering, trim maybe

but that's the thing, since it has no tail, its control surfaces for yaw are next to none, so I'm saying it needs horizontal TVC for it. Maybe a gyroscope could also work

There's some rumor on Reddit that there's growing consensus within US defense establishment about merging F/A-XX and NGAD and abandon the full sized NGAD, this means their incoming NGAD might be closer to Shenyang's J-XDS instead of J-36 . The role of long range missile carrier might be given to B-21 instead. If this is true that means China might ends be the only country operating full sized NGAD in foreseeable future. This might beg question whether US' smaller NGAD and B-21 could take over the UCAV management role that full sized NGAD supposed to do.
