When the landing gear are retracted (which is most of the time, when in flight), they are flush with the rest of the aircraft, minimizing drag.
The zig-zag may be to minimize radar reflections.
That is exactly what the zigzag pattern is for.
It still produces a drag especially at supersonic speeds.
If it is completely flush it doesn’t need to be zigzag does it?
Besides that the intake doesn’t look like a supersonic intake.
Again. This is a copy of our drones. Our drones are close to but not
supersonic. So why would theirs be supersonic and ours not if they look the same?
