J-20 5th Gen Fighter Thread VIII

[Deino]

63106 is the 300th vanilla J-20 built so it's one of the newest airframes we've seen so far

No or better to ask WHY should it be "one of the newest airframes we've seen so far "?

Both the 2nd AB and 131st AB have been confirmed after the 19th was most likely well established as a J-20-unit!

You realize that maneuverability isn't just used in dogfighting right?

"I think that slowing my plane down to a few meters per second and doing a backflip midair is useful for BVR combat, because obviously killing all of my velocity is the best way to dodge a missile"

Why are you even arguing? You come in, ask if the J-20 can do a Cobra, maneuver into and out of a stall, etc., and then try to link this to actual air combat? When are these maneuvers ever useful outside of dogfighting? Imagine an AIM-260 is coming at M2+, and you respond by pulling up your nose and stalling. How does this help? Sure, the missile now has to change direction because you've lost all speed, but missiles have better maneuverability than a plane, and a dual-pulse motor like the PL-15 (which I have no doubt is something carried forward to next-gen AAMs, and the Americans are trying to put on the AIM-260) will have no issue at all changing direction mid-flight, and then reigniting to accelerate into the plane which is just now recovering all the momentum it lost by stupidly performing a stall maneuver.

May 7th proved that Yang Wei’s philosophy centered around sensor fusion/OODA 2.0/3.0 is the right call. J-36 is a further development of this philosophy. If by some strange miracle a merge is necessary just let CCA handle it.

I doubt 2010s fbw delta canard with wvr missiles, EODAS and HMS is somehow afraid of it...though equally doubt CCAs will work as wvr escorts for J-20 that soon. There are far more achievable and important manned:unmanned teaming directions.

The problem isn't may 7th (which isn't atypical in Ukrainian experience, and is very relevant in Iran experience per contradictionem). The problem is how low altitude economy splashed out into air war - suddenly requiring weapons, which 5th and especially 6th gen fighters were optimized out of.

Has it ever demonstrated its high velocity maneuverability? If we're talking about nose-pointing, then I believe it doesn't have a notable sustained turn rate, nor minimum turning radius, at least compared to the raptor's from what was shown. Hopefully the upcoming changchun airshow proves me wrong.

For the apparent reason given by siege below, may I ask have you ever seen a swimmer breaking the world record in a bathtub? If not why do you expect any fighter jet does the demonstration in front of crowd? I am sure you will then demand demonstration video footage in PLAAF excersize, then maybe you should ask for the same demo from USAF for F-22 to prove that it can do everything it is said to be able to do?

You are now looking more and more like running in a circle and jumping back and forth neither willing to openly admitting wrong nor willing to return to silence.

You can’t do that at an Airshow since it will be performed at an altitude where the aircraft is too high to be observed.

To be fair, impressing observers is absolutely a role of peacetime military; no need to sniff at it (especially after recent parade).

But whether it represents extent of skilll/capability, and whether american military capability should be judged by Trump's parade is another thing.

That looked more like a failed attempt at a clean unloaded roll than some sort of deliberate maneuver to me. J-20s have a tendency to deviate their longitudinal axis from their velocity vector when rolling, aka "tumbling", and to my understanding this isn't a good thing because it hinders roll rate and bleeds off more energy

Question to the forum ...

1. Did the J-20 perform the same maneuver more than once (eg. on different performance slots or different days)?
2. Has the J-20 not been seen doing rolls without deviating?

Is a repeatable controlled action a "failed attempt" at anything?

Some nice close-up images of a J-20 on static display at Changchun Air Show + flight performance images.
