- Prezentacija radarra Selex Galileo - GRIFO u PDF formatu :

- Radar je izuzetno lak - okvirno 120 Kg, modularne konstrukcije, prilagođen kako i SD-10 tako i AIM-120, otporan na ometanje. U JF-17 blok-2 najavljuje se močniji radar. Tačno vek upotrebe motora WS-13 je znatno kraći od RD-93 ali je Kina svojevremeno iz Rusije kupila ceo kontigent od 200. motora RD-93.
Razvoj WS-13 motora se idalje intenzivno nastavlja. I sa postojećim RD-93 odnos potiska/masa je u korist snage . JF-17 je specifična kineska multiror platforma koja objedinjuje kako zapadno tako i istočno naouražanje i elektroniku. U gornjim slikama kolege ANTIBODY može se videti odlična finalna izrada. ( From above pictures of our coulege ANTIBODY we can see excellent final consstructions of each particular part-body of JF-17 ) .

Grifo bas i nema neke veze sa JF-17. Jeste da moze da stane u njega ali ga nemaju, imaju kineski KLJ-7 a i na Block II ce biti kineski radar. Grifo su Kinezi kupili i ugradili u F-7PG i JL-9 a i bogato koristili za svoj program preko reverse inzenjeringa(100 % su ceprkali po njemu).

@VITEZ

Klimov unapredjuje RD-93. Pominje se forsazni potisak od 100kN.

English:

Klimov works on upgraded RD-93. Data says 100kN of trust on AB.

nabil-
WMD-7 has performed better than expected in all weather, foggy, day night conditions in China and Pakistan. It has replaced Chinese legacy pods and is now the standard targeting pod in PLAAF service. In PAF, it falls between the SNIPER, ATLIS, slightly inferior than former, much enhanced than latter. Should be on par with Litenning 2 at least.
requires One hardpoint for now, should be on chin pylon from second blk onwards...

klj-7 currently has 550 watt output power and is powerful enough, but plans are in place for locally produced radar to have 600 watt (yes folks, 600) watt which will give it as much power as in APG-68 v9 ! but its radar antenna size will remain same. ISAR will be introduced, other modes will remain same but range will be increased. Overall, i expect it to be as capable as V9 in general capability but less in range. MTBF is around 300 hours. AESA is being worked out in China and is going through final trials. Blk 3 will have AESA but it will be tested on a prototype in China and then in Pakistan......

The more powerful transmitter, more options available such as more range, functions, processing speed, cooling, etc, although range greatly counts on antenna size too...Also, ESA antenna can be enabled on current klj-7 too !

How much do you want from a light fighter? Its radar can guide four, not two sd-10s simultaneously, search range is 150 kms, MTBF 230 hours, 30 modes of functions, this all gives it a good cost to performance ratio, is being improved and built in house, better than the rest of our radar inventory except the APG 68 V9 but than V9 is better than most pulse dopplers in the world anyway


----
a-5 retired, next in line are early mirages (non rose models), f-7s (only p, not pg), this should be completed as new batches of jft are inducted, within next 5 -7 years at best. Grifo-S is not exactly same as old Grifo-S 7 and I give u the reason why. After fiar presented s-7 to paf, it seem impressive as it had high power and excellent anti jamming, decent range, robust architecture but it lacked in multiple engagements and track range, it also had inherited flaw of unable to communicate with indigenous, chinese weapons. What was presented by fiar as the Grifo-2000/16 was any day, a better option as it had more range, better features. this was discussed with fiar and they came up with and unified version having different antenna, range, processors, features in a customized variant known today as Grifo-S, this can also be observed in the brochure. It was defeated by a more capable radar in all dimensions that is known as klj-7......

---



F-7= Grifo-7=200-250 watt

f-16 blk 15= 300-350 watt

Rose Mirage= Grifo M3= 400-450 watt

Grifo-S (JFT earlier) =500-560 watt

first at all,APG 68 V9 has power output about 5,6kW..it is a lot more than 600w in the Jf17 Laughing
i think your information was false.second out there there is a lot of more powerfull radars on the market, and they are also based on pulse-doppler system.the power of APG 68 V9 is in the so called "burn through"capability,and ofcourse in range.


no one says that the JF17 is bad,we all try to figure it out how good is it.but we all need some facts,some numbers,thatßs why i asked you about these informations.ok,you said that the chinese radar was tested against italian and french radar-can you give us info which italian oder french radar was in the testing and under which circumstances?

best regards

Maybe 600w is average power not peak power?

believe me, it is still not enough power.absolutely not enough Wink
mislim da je u pitanju greska i da je antibody mislio na 5,5kW kao na snagu koju ima sada i da ce se ici na 6kW.

Confused

Most radars in Su-27/30 family have average power around 1kW or little higher:

I really dont expect to see some high powered in JF-17. Its nose is small and there wouldnt be big benefit installing powerful radar with small antenna.

Rafal is nice example.

the peak power of grifo7
[P2801] is 100kW and its probably the weakest radar in paf inventory f-7p , so i will ask nabil what he meant by 250 in this case

in the previous page ive posted the nose cone sizes which in case of jft is greater space as compared to the grippen and rafale , so ''space'' is not the problem

100kW peak power? Could be typing error. Only MiG-25 had such powerful radar.

Here is interesting text:

Citat:This was a much more demanding requirement because of the smaller space available and lack of a cooling system. To this end simplified version was developed, the Grifo-7, which weight only 55kg (120 LB) and has 450W power with 850W energy dissipation. The modes available are search, single target track and air combat (super search, bore sight and vertical) modes for air to air operations, and air to ground ranging for ground attack.

I used Rafale as example why use of very powerful radar inside small nose isnt justified investment.
