the leading edge is swept back at a greater angle inboard of the engines and for a short distance just outboard the engines.In fact, this is the second prototype, which is standing since some time at the CFTE part of the Xi‘an-Yanliang facility … the two additional prototypes no. 03 & 04 are located further to the left at the XAC facilities and manufacturing complex.
You mean a different leading edge angle left and right to the engines or do you see a kink only outboard of the engines?
Also, the aileron droop, and the great length of the ailerons shown in the photo that leave little room on the trailing edge outboard the engine for separate flaps, suggest the ailerons are used as part of full span flap system for take off and approach. this is different from E-2, whose flap system seem to use only the part of trailing edge inboard of the ailerons. notice to leave enough room for separate flaps, E-2’s ailerons are much shorter compared to the drooping ailerons shown in the photo above.
If full span ailerons are indeed the case with the Kj-600, then I suspect Kj-600 also has over wing spoilers for roll control during take off and landing. that means Kj-600 has a much more complex wing than the E-2.
Also if the deduction that Kj-600 uses a full span flap system is correct, then it suggest the KJ-600 is either designed with ski jump take off in mind, or it has much higher wing loading the E-2.
