China Flanker thread

This one, straight from their website. It's an old picture really and its definitely not a mechanically scanning slotted array.

Maybe someone can compress it. It was a rather big poster and it has been posted in both the CDF and AFM forums. It showed a picture of the radar, that is completely nothing I have seen from existing both Russian and Chinese designs based on the servos and box components but didn't even say its designation.

It is possible that two radars were developed because China has two competiting firms from Leihua and NRIET. But NRIET has been winning all the contracts from the PLAAF with the exception of the JH-7A, and there is a rumor they want to change even the Leihua sourced radar (JL-10A) of that to NRIET's.

For example, Leihua's SY-80 competed with NRIET's KLJ-6E for the J-7G contract, and it appears to have lost. This despite the SY-80 is capable of using K band (higher than X/J band).

I am now leaning in the position that PL-12 and SD-10 both have different seekers. The PL-12 seeker is from NRIET while the SD-10 seeker is from Leihua.

The rumor for Leihua's candidate for the J-11B contract was something called the JL-15 aka Divine Eagle, where as NRIET's KLJ-4 had the code name 'Falcon' but the 'Falcon' radar turned out to be KLJ-6E for the J-7G.

There is a photo in NRIET's website that shows an ultra low sidelob array that looks like phase array. While it's oval shaped, it does not like like it is the one used on the KJ-2000 AWACS, so it might be for a fighter.

Possible was PESA.

Hmm chinese has so many secret projects and all going at the same time you never know what may come out. About the AESA or PESA radar are there news of when it was tested.

 

[tphuang]

Possible was PESA.

hmm, AESA radars
APG-63v2

APG-77

APG-79

AMSAR

PESA radar
N-011M

Zaslon

RBE-2

you can check this side for the Zhuk series phased array radars, they are the ones in the middle.

Thanks tphuang, I saw this concerning the rafale's radar.

Is it reasonable to say that AESA is more advanced that PESA

 

[crobato]

Yes and AESA is also much more expensive than PESA.

Also here is a NRIET mechanically scanned array in comparison to the other picture.

Here are some of the J-11B's component systems, though only a few are even named. Here you can see for the first time ever the MSA radar and the digital cockpit.

Thanks crobato but on that last pic the one posted on centurychina what's the name of the radar ??? Do you have the details

It's interesting for the electro-optical radar, they pointed at somewhere on the wings, I thought they would be pointing at the IRST, which is forward of the cockpit.

I looked back at that nriet picture a little more, the first impression I got was that it looked kind of like APG-77. Now I have a little more doubts.

according to worldairpower journal,early variant of MIG-29 and SU-27 IRST do not adapt modern focal plane array.but Chinese version designated Kuang Hong-1 use gen-3 IIR focal plane array detector.giving the detection range 3~3 half time detection range over SU-27SK IRST.

While likely it was a mistake and that irst will be on the same place as su-27
has it, wing root mounted irst is actually a very good placement. Coupled with laser rangefinder and marker unit, from there it can be used for laser designation of targets on the ground. And since it would be a bit off from the body of the plane, it would have decent lateral coverage as well.
