From flying J-16 upgraded to J-20 (机头到底有啥玄机，一上央视就打码?)

However if You look closely, that grey stripe in the middle of the inkate was always there.

BY the way ... is this another new LRIP-bird?

At least on 2021 this area was grey and not brown / tan

... and on again older birds even plain yellow.

May be it is still 2021, just coating new paint. I will try to ask the phtographer.

A pair of freshly minted J-20s caught flying yesterday(only one shown in the pic)

Interesting. Do You have any more recent information on the current J-10C production? Seems as it has been slowed down a bit but given 2-59 spotted already in late 2016 they must be already producing batch 03 aircraft.

Can't you just copy and paste the file onto PDF? They seem to have a bunch of bandwidth ...

To admit I see nothing but that x. There is no image, no file, not even anything my PC can open and if I copy and paste the link it makes nothing.....

Do you see anything?

I reblogged Popular Science’s September-9 article “China’s J-20 stealth fighter may be getting a new engine” on September 12. According to the article, there was a new J-20 prototype no. 2021 installed with a new WS-10X engine better stealth with 14-15 ton vector thrust that enables J-20 to conduct supersonic supercruise without using fuel-thirsty afterburners.

On September 20, mil.huanqiu.com published the above photos of the successful test of the new J-20 prototype no. 2021.

How is the credibility of this news?

Unreliable. Very much.

The WS-10X has no TVC and most likely about 138 kN of thrust.

The WS-10X has no TVC and most likely about 138 kN of thrust.

The WS-10B has a thrust of slightly less than 14 tonnes or around 138 kN. Since this is the WS-10B+, the engine's thrust is around 140-142kN ... a small but noticeable difference.

Better than WSJ and War is boring which is nothing but anti China stuff.

How about this:

Additionally, the WS-10X (possibly officially designated WS-10G or WS-10IPE) has sawtoothed serrations on the edges of its afterburning nozzles, like the F-35's F119 engine. The sawtooth edges provide a gain in stealthiness, as they redirect radar waves away from the nozzles. (The straight edges on non-stealthy engines like the AL-31 are major contributors to the radar cross section of a fighter).

In addition to the gains in stealth, the WS-10X is believed to provide about 14-15 tons of thrust. This may be enough power to allow the J-20 to engage in low supersonic supercruise at Mach 1-1.2 speeds. The Eurofighter Typhoon has a similar low supercruise capability, which means it can hit supersonic speeds without using fuel-thirsty afterburners.
