1. 3D Cutaway of Chinise 6th Generation fighter model

 Like the other 6th generation fighter models, the chinise one also has wide wing area with two engines; combination of the two will provide more range, fuel, and capacity for electronics. Indeed, configuration is very similar to other countries' proposal. 

Interesting points are splited complex LEF, relatively small engine, and distributed aparture sensors. LEF will provide efficient cruise and high AoA envelope while the small engine will be adaptive for fuel efficiency. The distributed sensor will give better S-A capability.


2. CFD? of 6th generation fighter planform

 At unknown Mach number, Cp value is shown for moderate AoA region. Compared to Fig. 1, this shape is more focusing on high speed cruise; more swept for both LERX and main-wing.






3. CG

 Unlike upper two pictures, it is more conventional and similar to FCAS. Caret style inlet is remarkable because J-20 chosen Divertless style.
