J-20 5th Gen Fighter Thread V

[JayBird]

This is some of the pictures from the research paper of the Snowy owl.

J20 is long range deep strike

J31 is multi role smaller frame

Seems as if Trumpeter has its revised kit of the J-20 '201x'-preserials finished

When that baby comes out, I will definitely get it and replace my existing J-20 "2001" model by Trumpeter

RaibbowBear (BaiWei)draw this new CG base on the old Snowy owl design and research paper and call it the Sea owl.

The length of the fuselage suggest a high premium is placed on low supersonic drag. The extra canard suggests not so much. Which is it? A fast super cruiser or a only somewhat stealthy airframe with some weight distribution problems?

What did you mean by extra canards?

Canards are actually rather optimal for supersonic drag...because they're better trim devices at supersonic speeds than tails are (aerodynamic center shifts rearwards at supersonic speeds).

I think he was referring to the Snowy Owl design.

Ah, I see. Nevertheless, design criteria is still the same, as the two projects were competitors. SAC went with triplane design to specifically address PLAAF's requirement of controlability up to 60 ° AOA.

It's interesting how they came to their different design decisions. CAC decided to challenge itself with the FCS to reduce the number of compromises they had to make, while SAC ended up going with a more conservative approach.
