JF-17 Thunder Multirole Fighter [Thread 4]

[ufone]

Using compost will kill the aim of the object but what about using light weight engine, light wt yet durable frames for all those system that r being installed.

---- jas 39 gripen NG characteristics would be closely met by successive blks of jf17 --
• More Internal Fuel, New Landing Gear
• Increased Payload
• Increased thrust
• Increased range
A hot engine change can be made in 45 minutes by a team of three.
10 maintenance hours per flight hour, includes all depot level maintenance.
The Gripen can be refuled and rearmed in less than 10 minutes.
The Gripen costs less than 2000$ per flight hour.
Airframe life is 8000 hours.
The Gripen can take off and land in less than 600 meters (2,000 feet).

Well i have seen most of the forum and its always mentioned that JF-17 is superior to Mig-29 (except the SMT version of course) then there is JF-17 is superior to F-16 (initial versions Block 15 and inferior to block 50/52)
My question is which block or version of F-16 and Mig-29 is the thunder most evenly matched to??
Thanks in advance..

Wing loading
In aerodynamics, wing loading is the loaded weight of the aircraft divided by the area of the wing.an aircraft with lower wing loading will be able to take-off and land at a lower speed (or be able to take off with a greater load). It will also be able to turn faster.

Two very different area wings can provide the same lift by flying at different angles of attack (and hence different lift coefficients). This is a big reason why aerodynamicists tend to work in coefficients rather than absolute forces.
Since weight is usually an input, the lift is constant. So more area means less lift coefficient (same lift), and lower drag.
Sweep, span, and area are all totally independent.
Wingspan

Wing loading
In aerodynamics, wing loading is the loaded weight of the aircraft divided by the area of the wing.[1] The faster an aircraft flies, the more lift is produced by each unit area of wing, so a smaller wing can carry the same weight in level flight, operating at a higher wing loading. Correspondingly, the landing and take-off speeds will be higher. The high wing loading also decreases maneuverability. The same constraints apply to birds and bats.

Wing loading is a useful measure of the general maneuvering performance of an aircraft. Wings generate lift owing to the motion of air over the wing surface. Larger wings move more air, so an aircraft with a large wing area relative to its mass (i.e., low wing loading) will have more lift at any given speed. Therefore, an aircraft with lower wing loading will be able to take-off and land at a lower speed (or be able to take off with a greater load). It will also be able to turn faster.


Fuselage lift
The F-15E Strike Eagle has a large relatively lightly loaded wing

A blended wing-fuselage design such as that found on the F-16 Fighting Falcon or MiG-29 Fulcrum helps to reduce wing loading; in such a design the fuselage generates aerodynamic lift, thus improving wing loading while maintaining high performance.
[edit] Variable-sweep wing

Aircraft like the F-14 Tomcat and the Panavia Tornado employ variable-sweep wings. As their wing area varies in flight so does the wing loading (although this is not the only benefit). In the forward position takeoff and landing performance is greatly improved.[11]
[edit] Fowler flaps

The use of Fowler flaps increases the wing area, decreasing the wing loading which allows slower landing approach speeds.

GUYS , PLZ compare these variables between jf17 and grippen.. does grippen seam to have relatively better calculations?

 

[khurasaan1]

umm ..okay quite interesting discussionz....lol
Im wondering ..what blk-II JF-17 will look alike...???

 

[S-A-B-E-R->]

Is the programme for the KLJ-10's processor code written in Pakistan?

klj 10 is for J 10 not jf 17 klj 7 is being manufactured locally and software is open for adjustments and modifications for paf .if thats ur question

 

[TaimiKhan]

JF-17s coming to Peshawar on 25th, by 27th hopefully the normal sorties would start taking off.

Some ground crew of PAF and Chinese technical staff already in Peshawar for advance preparations and stuff.

And 2nd Sqd might be raised on 23rd or a day or two earlier or after.


And as for the Indian General, just an advice, kindly make your intelligence gathering with respect to PAF more effective or consult defence.pk

I hope everything will be fine and on schedule....

yipppppppppppppppppy!!!!!!!!!!!!!!!!!!!!!!!

 

[alimobin memon]

by the way some guyz say blk2 will have aesa and some say upgraded klj7
1st question : china hasn't build aesa radar then what is chosed instead?
2nd question : will blk2 have increased payload like in gripen to gripen NG?
kindly reply please!!

 

[mymeaningislion]

@ alimobin
jane i lived with PAF fighter pilots and engineers from my childhood ........PAF doctrine is readiness and aggressiveness. so if u closely analyze all the air crafts that PAF possess. they match their doctrine. and on the other hand all modifications are made in such a way to make it more agile and potent force...so agility won;t be compromised and as far as radar and payload is concern yes every pilot want a good electronic sight and more missiles but number of factors causes interruption as R&D cost and procurement cost etc....but to satisfaction of all brothers...some radars are smuggled didn;t know the identification but they tend to reverse engineer it......source radar engineer.........and as far as payload is concern work is almost finish...but u know our airforce standard atleast hundred test would be conducted before even announcing....regards

Chinese AESA already active on J-10b and J-20, a version of J-10B is being tested for JFT but it will be installed from block3 at best. For 2nd batch, its indigenous variant of KLJ-7 as mentioned in JFT info pool thread. Payload will likely to be same but chin pylon (s) for EW, Recce pods will be introduced.

 

[farhan_9909]

what about the 2nd squarden induction

i heard that 2nd squarden will be raised by 23rd march

I thought it was already raised? The squadrons are raised with only 3-4 aircraft and it will be at full strength by the end of this year. But a senior pakistani member recently posted the squadron 1 was yet to get it's 4 spare aircraft? (14 operational + 4 reserve)
