JF-17 Block-3 -- Updates, News & Discussion

[StormBreaker]

Some sources indicate that T/R modules it is GAn based..

Are these 2 weighing machines ? Can’t differentiate the TR Module here from the other stuff.

GaN tech on Chinese radars would mean a lot faster, reliable and diverse operational capabilities.

If HQ-9B uses GaN TR modules, What stops china to use same tech on Aircraft radars ? Miniaturization?

Air Cooling Currently gives 2 main advantage
1 they dont need to re design the whole Nose Section and have a more powerful engine.
2nd This can be installed on 2nd Block.

In regards to air Cooling not good enough that depends on the materials being used and design of the system itself, If Chip is designed specifically for air cooling and layout supports that it shouldnt affect its performance that much.

Liquid Cooling is more of a brute force way to keep everything cooling and pushing it to its limit.
Since none of the details of both air and liquid cooled radars are available nothing much can be said.

Take an example of a normal average laptop/pc fan cooling system and a liquid cooling system with tubes and all.

My guess is air cooled radar chosen for fleet commonality as it can be installed on previous JF-17 variants.
170km range against fighter sized targets (from some sources that figure is vs 3m2) is pretty good.

Can the article be purchased from Janes as one off item?

Which KLJ-7A will be used? The one with side panels or the other one?

If they really made a new version that is air cooled then it probably will have lower modules.

If the article standalone was purchasable, i would have been the first one to do that... But IHS website seems so not user-friendly. Nothing is clear. If i go to client login, there is no option for registration.

@WebMaster Are you subscribed to Jane sir?

I think this is LK601E

 

[Deino]

Pardon if I missed it, but which source confirmed that an KLJ-7A varaint was chosen for the Block 3 and even more that this is an air-cooled variant?

Read all the the way to the end about - PAF finally selected NRIET KLJ7A AESA RADAR for JFT Block III.
.....and it says Air Cooled!!!!

Deliveries of the first 12 of 26 twin-seat JF-17B Thunder multirole combat aircraft on order for the Pakistan Air Force (PAF) are expected to commence "in the near future", PAF officials have told Jane's .

Eight of these aircraft were built at the Pakistan Aeronautical Complex (PAC) in Kamra, while the remaining four were constructed by the Chengdu Aircraft Industry Group (CAIG) in China, where the aircraft type is known as the FC-1 Xiaolong.

The aircraft, several of which are equipped with aerial refuelling probes, had been rolled out at PAC Kamra in late December 2019 during a ceremony that was also attended by the PAF's Chief of Air Staff, Air Chief Marshal Mujahid Anwar Khan. Delivery of the remaining JF-17Bs is expected to be completed by 2021.

Speaking to Jane's on 20 January, ACM Khan explained that the JF-17Bs will help to streamline the PAF's training process for the Thunder. "The JF-17 pilots are currently being posted to Lockheed Martin F-16, Chengdu F-7PG or Dassault Mirage IIIEA ROSE aircraft before converting to the JF-17," he said. "But they will start going straight to a JF-17 OCU [operational conversion unit] after completing their advanced jet training." ACM Khan added that this "will ensure that pilots transitioning to the Sino-Pakistani jet are a lot younger than they are now".

The JF-17B prototype made its first flight in China in April 2017.

Meanwhile, the PAF revealed that after a lengthy evaluation the air-cooled Nanjing Research Institute of Electronics Technology (NRIET) KLJ-7A active electronically scanned-array (AESA) radar has been selected for the Block III variant of the JF-17/ FC-1 Xiaolong, the first prototype of which made its maiden flight on 17 December from CAIG's production facility at Chengdu-Huangtianba. PAC Kamra's newly appointed chairman, Air Marshal Syed Noman Ali, said a second Block III prototype will assist in May with the test and evaluation process.

Client login if you work for defence company as said by another member.

You have to subscribe for a year. That's what "Jane 360" tab on homepage is for.

Alan warned from AFM and Jane's magazine. He was invited by PAF at Kamra a few days ago.

I think this is LK601E

Yes this is LK601E which is the air cooled AESA option. KLJ-7A is not aircooled. Both offer the same performance so doesnt make a difference whichever option PAF chooses.

If Alan says air cooled KLJ-7A then it is what he says.

Kindly don’t discredit him or Jane’s for providing authentic info with verifications before posting and during writing.

Why you all forget, in an interview, it was said, “KLJ-7A, LKF601 and a THIRD Type is being considered”

 

[Pakistani Fighter]

THIRD Type

I think that was GrifoE

I think that was GrifoE

It was not mentioned by name so it could be anything. Don’t makeup names

You cant really compare Laptop Cooling with Any Desktop Cooling.
And Intel mostly use rubbish Coolers, to real get the performance out you have to use After Market Fans hence i said materials and design will matter alot.
