hey guys i just found this artical on WAFF but with no links.... its suppose to be from a chinese aviation forum...
JF-17 II: Evolution Continued
The JF-17 is a truly remarkable plane. Starting from the basic designs that Chengdu and the PAF were tinkering with, the Super-7 with basically a MiG-21 with side intakes, it has evolved into a completely different beast. The Internet Military Aviation community was taken by complete surprise, almost shock when the JF-17 came out with a modern cockpit, DSI intakes and previously unseen quality of build.
Yet, when even the most ardent followers of the program had thought that the JF-17 had fully evolved, it has once again surprised all of us in its next evolution. It is likely that this evolution is going to take shape after the second batch. Changes are comprehensive and across the board and include greater range, lower RCS, AESA radar and a new engine with greater TWR (thrust to weight ratio).
The lower RCS is to be reached using new materials, including advanced composites. A new RAM paint is also rumored that is said to be similar to that being used on the F-35. The nose will see comprehensive redesign and is rumored to incorporate a new AESA radar set of Chinese origin. The single tail is to be replaced with twin-tails similar to the F-35. A new DSI is also projected that will further lower RCS.
The TWR of the engine is projected to increase with the WS-13, which are likely to go into the second batch. The iteration of the WS-13, possibly the "WS-13A" is likely to go into the stealthier JF-17. This will marginally increase the TWR further from the WS-13, which itself will increase the TWR marginally from the RD-93.
However, this increase in the TWR of the engine will be moderated by the increase in the wing size, greater internal fuel and the twin tails, amongst other weight increases. On the other hand, newer materials and over all weight decreasing projects in turn will moderate these weight increases.
The stealthier JF-17 will incorporate a larger wing, improving higher altitude maneuverability. This is a crucial aspect that is increasingly becoming important in BVR combat, where the higher and faster jets can in some form take pot shots at slower and lower BVR platforms. Another aspect of the larger wing will be increased internal fuel carrying capacity. This is addresses one of the areas that the JF-17 is weaker in - range and the ability to stay on station longer.
The nose, vital areas of the cockpit as well as a whole host of other technical areas will be addressed. the nose will in fact be fully redesigned around a new AESA radar and be formated to lower RCS. The DSI design is also being redesigned to better accommodate and optimize higher altitudes and higher speeds. A second generation of the onboard information collection, dissemination and display will be incorporated.
However, thrust vectoring will not be incorporated, neither will be internal carriage of weapons. This planned version may or may not go into production. However, all, most or many of the changes may be incorporated into the third batch of 50 being ordered by Pakistan. My personal opinion is that this prototype is more of a technology demonstrator. Major changes would not be appropriate unless a major export customer is found. I would think however that all the minor changes, as well as a few crucial major ones will be incorporated. This is likely to include the new engine, as well as the larger wings. Stealth features should also be incorporated but major redesign is likely to be avoided for the 3rd batch production models (such as twin tails and new nose). This version will be targeted for export and will not be part of the Chinese arsenal.
Much of this data is based on rumor, informed speculation and some insider sources.
