Serrations were the first thing I thought of too.Depending on what stage of completion the various parts of the airframe were built to prior to transport, it may well be possible they've chosen to transport these major subcomponents at earlier stages than they did for the initial FC-31 V1 airframe.
A few other observations;
- is the airframe being transported in the rear a second duplicate of the same aft section that we are seeing closer to the camera? I.e.: are they transporting two aft sections of the same kind of aircraft?
- is it just me, or does the "front" of the aft section (both closer to the camera and further from the camera) seem to have some "jagged" parts protruding despite the not-quite-airtight tarp covering them? I.e.: do they look like serrations to anyone else?
If these aft sections are indeed related to FC-31/J-XY in any way, I note that there doesn't seem to be a central tailsting/boom like on the FC-31 V1 and V2.
Of course, on FC-31 V1/V2 that central tailsting/boom was quite small to begin with....
OTOH, I also note that the JL-10 doesn't have a central tailsting/boom.
So who knows what this thing is. There are good arguments that it may be a FC-31 derived aircraft like J-XY, or it might only be JL-10.
剑门关服务区 or Jianmen Pass highway service area (from the very back of the second pic we can see the writing "门关服务区" on a yellow boardEsp. since that attachments for the tails are missing
Do we know, WHERE these parts have been spotted?
I didn't see this at Weibo and I won't say where I found it.
Based on the latest discussions at Twitter, this is: "剑门关服务区（Jian Menguan Service Stop). It is a major service stop on G5 National Highway and about 250km away from Chengdu."
So the question now is: Why then a transport of parts / modules from Chengdu/CAC to Xi'an? Could it be for static testing of another variant? Maybe the twin-seater or WS-15 integration? Or are such transports quite common but only not documented?
I would choose the first option as the answer. But I don't think the second option is exclusive to the first option.So the question now is: Why then a transport of parts / modules from Chengdu/CAC to Xi'an?
