gripen thrust itself isnt too high and it is slightly heavier too
gripen thrust itself isnt too high and it is slightly heavier too
there are some other confusing figures about payload and engine output and range etc. klimov's poster says RD93 has 96KN thrust but PAC is still showing the 10 years old figures, in the information pool thread tempest II has posted some snaps which claim weapon load is >4000. It was 3600 then 3800 and now >4000, confusion confusion confusion
when will PAC update its website??????![]()
The engine pushes wings which generate lift.
climb rate depends on the T/W ratio and the amount of lift the JF's wings generate.
One of Dassaults early experimental delta's had a fairly small engine and not too high a T/W ratio.. but it generated a lot of lift and could climb like a rocket.
http://www.pakwheels.com/blog/articl...for-the-laymanJF-17 has a maximum ferry range of 2037km and a maximum combat radius of 1352km with speed of Mach 1.8. It has a service ceiling of 54000 ft with the climb rate of 154 m/sec.
Don't know how credible as it is clearly wrong on ferry range figure but combat radius is written correct along with top speed.

The both PAC and AVIC websites don’t get updated regularly. What I have noticed though is that the info gets confirmed slowly and in trickles. We should try to connect the dots – yes sometimes that is not easy and we might disagree on which dots to connect but as long as we have a healthy debate that is good.
Concerning the power of the RD-93’s improved performance, my first “***” was none other than the late Sqn Ldr Hussain saying the JFT has a TWR of more than 1.01! Next “***” was the Klimov poster of 96kN. Then we have the Dubai presentation of 249m/s climb which surpasses the Gripen E/F and the EF-2000. … … And of course we don’t question the power of the Gripen E/F or the EF-2000 … … for the simple and sad reason that they are Western and not cheap Chinese fighters!!.
I could be wrong but I believe that the max climb rate is more from the engine thrust than the wings. Yes wings still provide some lift. The other climb rate is the optimal where you try to burn less fuel and rely less on the engine but more on the wings …???
We also have sources saying the Chinese were asking the Russians to improve the engine. So, should we be surprised or be shocked that there is a more powerful engine out there. When we know the “sister” RD-33K has got a lot more power anyway.
Another possible hint for the improved engine is the >4,000kg (4,600kg) external stores.
In all these “dots” I can see a pattern and some consistency that point to an RD-93 that delivers more that the original 84kN.

^^^its good to keep the enemy guessing on the capabilities of the JFT. in the 65 conflict, the IAF had to assume that all 120 F-86's were equipped to fire A2A missiles when in fact only 25 Sabres were fitted for the early model Sidewinder (GAR8). it was a huge advantage.
Found this old picture, which was made by me, someone on the hard drive of my laptop and hence thought to share it. A PAF JF-17 (10-113) shooting down a Su-30MKI with SD-10A.
just one thing..... blk 2 is more capable than many (including me) think and PAF chief deliberately said a few things that dissapointed many. You can guess the rest. Offtopic, but ZDK-03s will arrive any time in early December.
This video is captured by a friend of mine on FB on 1-Dec-11 before that another friend of mine from FB reported that he has seen ZDK-03 in Chaklala 28 or 29 November.
Video is captured in Karachi Gulshan AREA while Karakoram Eagle is on its way to land on Masroor.
Bhai jan, we have already received one in Nov 11

See, the number you have quoted kind of prove the point I was making.
High climb = High Lift = Large Wing Area OR Higher angle of Attack
Large Wing Area OR High angle of Attack == High Drag
High Drag needs more powerful engine.
So unless we know that the engine's power has increased or PAF has managed to decrease the plane's weight,
we need some more dots.
