Some illustrations on gatling guns allegedly intended for fighter aircraft. Does anyone have access to the paper(s) from which these illustrations are taken so that I can confirm whether the speculation is correct? Thanks in advance.

I've been looking for this paper, I believe it's titled "外能源转管航炮的精度修正方法" from CAC, so far no luck finding it.

These diagrams appear to relate to two papers as

.

The first paper "Accuracy Correction Method of Gatling Gun With External Energy" from CAC is the one Shilao et al. also referred to pertaining the gun speculations.
Rest of the paper withholding, it appears somewhat incidental to see authors use solely F-22 as a background reference.

The second paper "The finite element analysis of blocking mechanism of a gatling aircraft gun" is not from AVIC but by authors from CSSC institute 713 (designer for the Type 630/730/1130 CIWS), hence there appears to be some understandable "joint" efforts in this development (providing they are related).

Thank you. You've come through yet again!

The question is not about the accuracy of the Simulation, but the "estimate" RCS difference between F-22/f-35 vs J-20 because that RCS difference will be the biggest deciding factor in a BVR fight


Is there no reasonable guesses we can make about the RCS difference between these two planes? I know there have been various Radar simulations being published which only look at the shaping of these planes.
The first thing you should know about RCS is that single figure measures are as meaningless as trying to understand how two cars might do in a race just by looking at their listed top speed.

For something that requires as much complex engineering as RCS it shouldn’t be surprising that actually there is no way to make a meaningfully reasonable guess at actual figures without reproducing at least some of that level of rigor, which no one in open source world has really done to a level where the caveats aren’t basically making the information derived utterly useless.

Everything that you need to know about that video and your current line of questioning is in my last reply.
Ignore, ignore, ignore, stop stop stop.


Just don't even think about that video and the question it raises. As I wrote in my last reply, no we don't know what J-20's RCS is and we don't know what F-22's RCS is. Public estimates are essentially useless.



So just don't even think that this is a question we can even ask or an answer that we can ever get -- think of it as something unattainable, and anyone who claims to know the answer in a relative way with number is full of rubbish and needs to be ignored.



Again, let me repeat -- DCS is just a video game. As a rule of thumb, do not think about extrapolating anything about real world performance or capabilities (relative or otherwise) from it.

In fact, I would say it is beneficial to pretend that DCS just doesn't even exist. Don't look at any DCS video on youtube, and don't ever play DCS, and don't even talk about DCS.

The net effect of improving military understanding will be better that way.
