I will highlight two things that AVIC CEO said about the J-31. First, the project is purely privately funded. This settles the speculations as to whether the plane is government backed or military backed. Secondly, the wings and body is one integrated piece. One engineer on the show said that number of components is reduced to 46% compared to third generation fighters. Fewer components means less seams, and less seams means weight saving plus shortened assembly time.
Putting the technical aspect aside, it is obvious those people on the show still hope to carve out a slice of the forth generation cake from the J-20 project.
So would the fuse center section/wing juncture be welded titanium, or carbon fibre?? I know believe the F-22 and possibly J-20 are welded/fused together??? oh and thanks for the translation.
