TR Air-Force TF-X KAAN Fighter Jet

The bottom (fuselage) Kaan is flat, which reduces the stealth ability. Are there any solutions?

The solution, apparently, is precisely in the plane of the bottom. All 5th generation fighters have such a flat bottom. Apparently, the roundness of the fuselage will not reduce stealth

Look at F-35, its anything else than flat.

Yes, not quite flat.
The KAAN and the Chinese fighter have flatter bottoms.
The 5th generation aircraft are remarkably similar to each other.
There is something related to geometry, in which I am, to put it mildly, far from an expert.

Do you have any source on that other than "but F-35 is bumpy" ?

Basic physics say that pure flat undercarriage is best for stealth. It won't reflect back unless you're directly on top of the radar or you pull the jet up to give an angle to said radar.

F-35's is probably a sort of compromise. And as Iskander said, it's mostly flat though a bit bumpy. I'm not exactly sure but they probably wanted to maximize space while reducing the impact on stealth as much as possible, it is a strike fighter after all, needs to be able to carry a vide variety of bombs whereas air superiority jets have sleek missiles that don't take much space width wise. Doesn't actually mean that the curvy, organic look is best for stealth. Even CCP 6th gens have a flat undercarriage.

Bro, flat belly generally means better stealth.
f35’s slightly rounded belly has been argued to compromise it’s stealth.
Rounded surfaces reflect back radar sigoals. Where as flat and 90degree surfaces scatter radar signals.

The thing about flat panels is that incident radar energy is reflected away from the radar aerial that emitted it, so the searching radar does not receive a return. Only if the radar energy arrives perpendicular to the flat panel will it be reflected back and received. In that situation, the ground radar will get a brief ‘glint’ return, a high-energy spike - and one contact is no use for tracking a moving target.

The B-2 manages to do that with curved surfaces. Some very clever engineering went into that, assisted by the extra computer power available to the designers of the B-2 compared to that available to the designers of the F-117.

F35 : still fairly flat but some curvature under belly apparent.

F22: distinctly flat belly

F117: totally flat belly

B2 bomber: rounded belly - but read above explanation

KAAN : flat belly like F22
