J-20 5th Generation Fighter VII

[Inst]

It's a pretty simple probability study using info we have posted back in this very thread at the time of the testing + google maps and reasoning.

Have a peek at the area size of Tibet. Then lookup the location of the airfield the J-20s flew from, and the distance of that base to the boarder. We can run with the BARS maximum range. Then decide how brave you want to be about your assumptions on just how close up to the LAC Indian MKI happened to fly from say Tezpur or Chabua, the same day(s) China flew the J-20 in an area around the base. And just what kind of distance do you get?

So did the MKI really detect J-20? Not likely.

Shigatse to Siliguri in West Bengel is about 300 km.

About the coplanar question:

On the 2001 preproduction, the canards are clearly not coplanar with the wing. So is 2021 series coplanar to the opposite wing?

Also worth posting, not because it's any good, but that it's incredible levels of bad. "Dual wing configuration". If you said double delta, I'd forgive, but now the Rafale and Eurofighter have a "dual wing configuration". No, it's not translated from Chinese, it's written by what seems to be an American.

Pro-tip: coronavirus supposedly has massive neurological effects.

Also:

This is from Taxiya purporting the coplanar wing / opposite canard theory.

The angle of the main wing is roughly -6 degrees. The angle of the canards to the main wing, however, is roughly 9 degrees. So that's actually tossed out of the RCS design theory, unless someone wants better measurements.

Shigatse to Siliguri in West Bengel is about 300 km.

Chabua or Tezpur, those MKI are anywhere from 500km+ to 700km+ away from their bases and the J-20s that were at Daocheng Yading Airport.

Unless you happen to believe that on those testing days India flew it's fighters over the mountains right up to Chinese airspace, and China decided to test the J-20 in a direction towards the Indian boarder. Maybe if they said one of their Phalcon detected the J-20 I'd give it more credence. But it was plainly a 'our fighter is as good as their new fighter' comment, made to questioning reporters.

But if you want to believe India ran those MKI up to the boarder and saw J-20s flying around the same, then more power to you. I'll stick with unlikely.

Since an Indian Air force chief is nevertheless an "Air force Chief", it is simply too offensive/deluded to suggest that anybody here knows better.

This statement ignores the political pressure Indian senior officers are under to toe the line of a nationalistic (to put it mildly) government. They have no credibility.

Why do the J20 have the vental stakes angled and in a position that hides the Engines...

The J-20's ventral strakes are angled to be parallel to the V-tail on the opposite side of the fuselage. The J-20 also makes use of this counter-alignment principle with the trailing edges of the canards and main wing.

you can see other details of planform alignment from this image, like how the housing for the canard actuators is basically a kind of fractal of the lower fuselage. We can also see that the outer edge of the inlet aligns with the V-tail. If we imagine a tangent line to the canopy from the base, that line would be parallel to the tail on the opposite side of the fuselage.

Note also how closely to the fuselage the canard is attached.

Simply put, we can't say the J20 is not LO from behind. What we can say is that J20 is probably relatively less stealthy from behind.

Less stealthy relative to what? To a J-20 with serrated nozzles? Surely. To an F-22? Perhaps. But the question (as you allude to) is by how much and is it militarily relevant. Suppose the J-20 actually has a few hotspots in the rear more than the F-22, good luck getting your radar in exactly the right position to exploit them for more than a fraction of a second.

The F-35 also went from the 2D thrust vectoring nozzles of the F-22 to serrated nozzles. That tells me that the loss (if any) to RCS optimization is acceptable.

Every so often, almost annually it seems, this thread discusses what some Indian article or IAF officer thinks of the J-20.
Basically every aspect of those past opinions and articles have been discussed to detail before and the same loop is always done basically every time.
Consider this a formal moderator warning that this particular chain of discussion has finished, any further posts continuing going forwards will be deleted.

China should enter serial production of J-20A (with indigenous WS-10C engine) because actual meaningful numbers of units is more important than individual raw kinematic speed. As Bltizo mentioned, a generation jump in avionic sensors and stealth is a vast improvement over existing PLAAF units, so just pump them out like sausages now for front-line duty.

Once WS-15 engine is ready, give front-line Western Pacific units J-20Bs (w/ WS-15 engines) and relegate the J-20A units (w/ Russian engines/WS-10) to Indian border region where it will still be head and shoulders above whatever India can field in foreseeable future.

That's what it's been doing for the past year already

Are there any estimates on the numbers of J-20's produced per year and total number produced so far?
