J-10 Thread III (Closed to posting)

[Inst]

I mentioned on CDF that it's likely to be a PESA for the large horizontal apertures. That would be the exit port for the radio wave generator.

It's not all bad news; if the holes are about the same size as the ones on the Zhuk-MSE, it should translate to around 1000 T/R modules, better than the one on the Rafale and about the same as the one on the F-16. That means when you get to the AESA level, the performance should be superior to the Rafale and perhaps the Eurofighter, which means the J-10B should have better or equal radar than the winner of the Indian MMRCA competition.

Bltizo: Because they managed to get information they weren't supposed to leak; according to the CMF thread, someone got invited over for tea by the PSB.

Ah that would make sense cheers ^^

The guy who got arrested was the one who took the J-15 pictures. They confiscated his computers and deleted a lot of stuff. Wonder what type of tea he got.

Wonder what type of tea he got.

Bitter oolong tea.

Single digit yuan (less than ￥10) per 500 gram, kind of "supply as you need" cheap tea; Chinese style "tea mug" container; repeated boiled water... something like that.

The PSB themselves drinks that.

I dunno, it looks more aesa than pesa to me -- I think there are individual tr modules on it compared to pictures of other pesas which have the more slatted appearance, but hey that's just me.

Then again there have been no a aesas that were so yellow before, and all pesas I've seen were yellow...

The key question here is: is this radar newly developed or has it already been tested?

If it is new, then there is no way the J-10B is going to use that radar. Huitong posted that the J-10B will be entering production this year. If the radar is new, it would have to go through years of testing and fixing.

Here's also a thought: wasn't the purpose of the J-10B to test 5th generation avionics? This could mean multiple things. It means that one or two J-10Bs would be converted to testbeds (possibly the one that was pictured recently), or it could mean that the J-10B would get AESAs.

The J-10B photographed is also in yellow primer; considering that the other J-10Bs are in PLAAF grey, it leads me to think that it might be a testbed.

A Chinese military official commented that the J-15 and J-11B may get AESA. If the less capable J-11B and J-15 could get it, then why not the J-10B? It's obviously not about the price anymore.

In short, I think that this particular J-10B is a testbed.

Sinosoldier: Chenium posted this on CDF. Was it before or after they switched over to the radar covering theory?

Who's big shrimp?

You really need to stop. Your entire theory for this been PESA is because you can't believe that China can technologically produce one when Russia hasn't been able to do it. You also can't believe that China can afford AESA radar on a smaller fighter jet. So you start with prejudice and then go from there. In the original photo, it was so remote, there is no way you can tell whether it's AESA or PESA from that. Now, the most recent pictures are more up close. You at least have legitimate things to argue about. The problem is that you lost all credibility by arguing for PESA situation with no clear photo evidence. People here are more likely going to think this is AESA, so you have to provide real evidence.

Now if we look at three photos from your Russian radar collection.
Zhuk-MAE

Zhuk-MSFE

Irbis

now, some American ones
APG-77

PAG-79

Now, even looking at the latest photo of J-10B's radar, I can't see clear enough to judge the rows of antenna. What I can say is that it is a canted antenna and also is not circular shaped. That seems to match those of other AESA radar (including Zhuk AE). I read that canting on a fixed AESA is to reduce head-on RCS. Whether that is also applicable to PESA, I don't know. But there are certain plenty of evidence pointing that way.

Tphuang, can you make a judgement with this picture?

What do you think about all the talk over on the Chinese sites about the radar actually being PESA, what's your take on their credibility?
