JF-17 Thunder Multirole Fighter [Thread 5]

[danger007]

130km is for 5m2 RCS target.

The MKI a loaded one will have RCS in excess of 15-20m2.now calculate the possible range(though i do know their is a limit aswell)

BVR are not fired at max range aswell.If the BVR range is 100km.the pilot will most probably fire it at max 70-80km or even more like 50km.

15 to 20m2??? huh..JF-17 can detect way before MKI take off..happy ..come back on track..

Here is some old info but should be helpful in our discussion for reference. From here ACIG Forum - Login

Some translations and points discovered by Hyperwarp in the AFM concerning an magazine published article of an interview with the designer of the SD-10.
"Efective combat altitude 0-25Km.
Ability to engage target 10kms higher or lower than launch altitude.
Range at 10Km altitude at M1.2 target at same altitude =70Km.
No escape zone for F-16 type target = 35-45km
Max overload=38G, Speed =4M
Plans to be also used as SAM system."
"Designer was asked at end to rate BVR AAMs. He rated Meteor as best BVR AAM, then AIM-120C, then his SD-10, then AIM-120A/B, R-77, Skyflash at equal fourth, then Derby, and last of all, MICA."
"What the designer said is that they used the same way AIM-120 calculated its range. target and launch aircraft flying at each other at 1.2 mach and at 10000 metres. The range is 70 km under such circumstance.
Also interesting is the designer basically said the russians "cheated" with R-77, as they calculated the max range with target and launcher flying at each other at 1.5 mach and at 12000 metres altitude."

A more detailed translation by Dongdong posted in the AFM forums:
"I just bought the BING GONG KE JI magazine with the SD-10 designer interview. The interview is pretty informative. Add my points for translation:
Ahout the max shot range:
The Deputy Chief Designer of SD-10 said: The parameter of “max range” is determined by the relative position of missile’s carrier and the target aircraft. The assumed conditions by various countries are different. So what the Russian said the max range 100Km may not be better than what we said the max range 70Km. The max range 70Km in SD-10 marketing promotion brochure is measured under the condition that both the missile’s carrier and the target aircraft are flying at 10Km’s altitude, both the missile carrier’s velocity and target’s velocity are 1.2Mach, their flying direction is reverse(head to head). AIM120’s test condition is similar to SD-10. However Russian’s propaganda is a little more exaggerated. For example, R-77’s test condition is: carrier and target are flying at 20Km’s altitude; each has 1.5M’s velocity, head to head flying. Under such a condition, the max range is 100Km. The problem is higher altitude means less aerodynamic resistance, plus the faster velocity for both the carrier and the target. The range is naturally longer. So you shouldn’t only consider parameters isolated with each other. In fact, our SD-10’s range is better than AIM-120A/B, a litter less than AIM-120C, almost same as R-77’s.
About ranking MRAAM:
Designer : It’s not easy to rank …..Various persons have various standards…
First of all, Euro’s Meteor should be No.1. This missile’s performance is very advanced, its range reaches 160Km.It belongs to next generation missiles. Next, I think the AIM-120C is more advanced. For original AIM-120 missile, whatever components, materials and craft are world first class. Now it is upgraded to Type C, it makes new progress on range, precision and anti-jamming capability. Following, It should be our SD-10. Then AIM-120A/B, R-77, Active Skyflash at equal fourth. Then Israel’s Derby, Derby has a comparable overall performance with the above missiles, but its range is relatively short. Last of all, MICA, its tech is not bad, however it’s a tradeoff between BVR and dogfight, so is naturally inferior to dedicated MRAAM.
Reporter asked : Our SD-10 has a good ranking. Why do you say our SD-10 is more advanced than R-77?
Designer: We adopted some technologies more advanced than R-77’s, so SD-10’s overall performance is better than R-77’s. For instance, our strap-down initial navigation system, signal processing system are more advanced than R-77’s. Our missile was developed relatively later than R-77.Some new technologies were not mature when R-77 was developed, so R-77 didn’t use the new technologies, but when SD-10 was developed, the new technologies became mature, so we adopted the new technologies in SD-10.
SD-10’s milestones:
Designer: We started the pre-research work for advanced radar guidance air to air missile in mid of 1980….
Phase1:mid of 1980 to beginning of 1990, key technologies study
Phase2;Started from mid of 1990, sub-systems development
Phase3:Started from end of 1990, missile overall performance verification test
Phase4:After entering 21st century, demo verification test
Now, the development of SD-10 has been completed."

Too much emphasis on the G factor. The G zone is good for other stimuli but but has very little role in modern day aviation.
Araz

Sir by reading this what is your opinion on with which model off F-16 we can compare Block II @araz

First squadron does not, as its meant for pilot conversion, 2nd squadron does.

And which BVR is used by 2nd squadron

 

[Tehmasib]

@danger007 on your avtar pic is friend of mine......good to see

 

[Zarvan]

@Aeronaut So by information which have got by this date what are the new things in JF-17 Block II and by which time it will arrive

Dubai Airshow 2013: Pakistan looks to Block 3 variant of JF-17

Reuben F Johnson, Dubai - IHS Jane's Defence Weekly

21 November 2013

At this year's Dubai Airshow officials from the Pakistan Aeronautical Complex (PAC) in Kamra discussed their plans for a future Block 3 variant of the Chengdu JF-17/FC-1 fighter now that the Block 2 model has a mature configuration. The aircraft is produced jointly by the PAC and Chengdu Aerospace Corporation in China.

"The Block 3 aircraft now exists in the form of a conceptual design and a list of mission requirements," said one of the senior Pakistan Air Force (PAF) officers assigned to the programme, "but no concrete decisions have been made about the choice and configuration of the onboard systems for the aircraft."

Where is block 2?

 

[Bratva]

Where is block 2?

In production.

@Aeronaut So by information which have got by this date what are the new things in JF-17 Block II and by which time it will arrive

Sir ye sawal app koi Souvi dafa pooch rahy hai... Pehlay Taimi nai bataya, oscar nai bataya,,, kitni dafa poochay gai? Ya phr angrayzi nahi samjh aati,, jo articles and newspapers yaha par post kiye hai us ko parhnay kai bawajood samjh nahi aa rahi kai Block 2 mai kaya kaya ho ga?

 

[HariPrasad]

In production.

Can you Pl enlight me about changes compared to Block1? Any change in Design , Engine?

 

[Bratva]

What are the changes compared to Block1? Any change in Design , Engine?

Fixed IFR, Upgraded Radar,ECM and avionics and integration of PGM, AGM , Air-to-Sea weaponry. No change in Design and engine. That would come in Block 3. And that's it's conceptual design released by Pak Aeronautical complex

 

[Rashid Mahmood]

JF-17 Block II – Ordered by the PAF in 2011 as a variant with "enhanced features".
Block 2 JF-17s incorporate greater use of composite materials in the airframe to reduce weight.

The JF-17 Block 2 is to incorporate an IRST

So it is Upgraded Block 1.

Good.

 

[trident2010]

you cant stop trolling can you? post reported

Trolling? I was replying to one of the previous posts.

 

[TaimiKhan]

So it is Upgraded Block 1.

Good.

Either you guys are missing the common sense part in the brain or due to being Indian can't stop being sarcastic or don't wanna understand a simple issue.

JF-17 basic design will remain the same, nothing dramatic will be witnessed, because if something dramatic is done with its design, it will not remain the JF-17. So whatever blocks will come, they will mostly consist of avionics related upgrades, and may be just some little bit of tweaks with the airframe design to further improve the current design of the aircraft.

I hope this is explained and understood for the last time, but again i doubt it when it comes to Indians.
