I think the intention was to avoid Aerodynamic drag(and strain) arising from those bay doors opening

The question would be, what creates more drag, the bay doors of the F35, that opens only for a few seconds, or the whole process of opening, closing (twice) and the extracted rail launcher that will be out for the whole time. For the SR missile bays this systems might not be optimal, but I wonder if a similar system has advantages for the main weapon bay, since the doors there are bigger and draggier.

The yellow parts fill up the "gap", so to speak, when the weapons bay closes. I guess this is done as an RCS reduction measure, but I could be wrong.

Just wondered, because these "gaps" could have been closed simply by making the doors a bit larger:

No it couldn't. The gaps are there so the guid rail could stick out when the bay door is closed.

Right, forgot about that.

Fangs out !

But I have a question, whether it waste the space, only one missile, I think it should have other better solution!!

I guess that partly explains the sheer size of that plane.....

it's not that big

it's not that big

It looks fatter than J-15, so it is a 40 tons aircraft no doubt.

Maybe it just has a larger wing area?

 

[gagaga]

Because the opened side weapon bay door bother a full maneuver of the Canard.

J-15 has larger wing area, but J-20 needs the internal weapons bays, thus its body is fatter than that of J-15 or other flankers.
