Swept Forward Wing

 

 Forward-swept wings offer low drag and improved low-speed handling characteristics, but they are extremely difficult to manufacture using conventional techniques. The use of advanced composite materials makes the wing rigid enough to withstand the forces introduced by aerodynamic stress, while simultaneously avoiding a weight penalty.

Jf-17E Block 3 : Thunder XL

Inspired from the F-16 XL project, this modification gives JF-17 Thunder a substantial increase in payload, range, and speed. Unlike the crancked arrow wing of F-16XL, this particular Jf-17 mounts a diamond shaped wing, commonly associated with YF-23 Black Widow. Primarily intended for Strike role, Block 3 because of its increased internal fuel capacity and payload, the JF-17 XL can carry twice the payload of the JF-17,  40% further. The increased payload was carried on 17 hardpoints, which were arranged as follows:
 
6 wing weapons stations (750 lb capacity)
4 semi-submerged SD-10A stations
2 wingtip stations
1 centerline station
2 wing "heavy / wet" stations (2000 lb)
2 chin stations for Targetting/ navigational pods.
