According to wall climbers on Weibo, no new AL-31 equipped J-10C or J-20 has been spotted at the CAC since September 2019.

Very large originals. Pardon the image size, but they are worth it. That last image is an older one.

According to wall climbers on Weibo, no new AL-31 equipped J-10C or J-20 has been spotted at the CAC since September 2019.

So it seems that the 4th aircraft, in latest batch of J-20's, has been rolled out and flown with WS-10's which thrills all J-20 fans to no end. We are all happy that the long period of time since the last roll-out has come to an end with 4 birds with WS-10's.

I would venture to guess the next batch is already well along in the building process, and who knows how many aircraft will be in the new batch, it wouldn't surprise me tremendously to see a few more aircraft roll-out this spring, maybe before?

but we will have to wait and see.

So i was looking at the J-20 primer pics and something i noticed...

Notice the aft section of the Three Aircrafts :



And most interesting...



What's with the ventral strakes of J-20 ? Am I seeing enhanced RAM application here? What's with the F35 V tails and Horizontal stabilators?
Is there no edge treatment of rudders on F22 ? I can see some treatment on the stabilizors of F22, but will it qualify as even an "edge treatment" ? Why so ?

Also , why isn't the same treatment for the Ventral strakes of J-20 applied for the Canards ? Wouldn't it help a lot ?

What extra sensors might be there within the canards of J-20? I think that could be the case since full treatment might interfere with these sensors.

China finally cracked the turbofan

J10C and J20A now indigenous

It has been, long time ago .........and don't forget J-11B/D and J-16 ... and JH-7A

The ventral strake is a fixed surface, the canards aren’t. I assume that they have different mechanical stress requirements. That said, they still applied the same treatment to the outer fringes of the canards and vertical stabilizers.

What are your thoughts on the post above regarding the differing treatments on the aft section of the 3 aircrafts ?

I am more Interested in the fact that f35 and f22 seem to have applied some treatment to every single body panel. While there is no such trwatment visible on the j20. As if j20 has ram treatment only on select places like the surface edges.

I noticed that too.
Didn't want to raise too many questions and stuff.
Either the Chinese have figured out a way to seal two panels together(thereby voiding treatment requirements)
Or a different manufacturing process/philosophy.
Or could have settled for less due to costs.

But since the Chinese seem to go for edge treatment, intake mouth treatment and a bevy of other LO focused measures...I think they good?
