J-20... The New Generation Fighter III

Dizasta1 said:

Somethings I noticed in this picture;

- The weapons bay doors do not have 'Saw-Tooth Edge outline'. Would these doors be modified at a later stage or is Chengdu planning to keep it the way it is at the moment?

- The main-landing gear's large door, previously seen in pictures of Prototype-2002 as being closed whilst on the ground and open only when taking off. Are seen here in the picture, open whilst being towed. Does this mean that both 2001 and 2002 have the same ability to close and open the landing gear door, when it wishes to?

Actually the main weapons bay does have saw tooth edges, it's just hard to see from this angle.

Here's a better shot -- still blurry, but you can see the saw tooth edges against the white background




The side weapon bays do not have saw tooth edges, but uses a larger arrow shape. Regardless, neither edge is ninety degrees to oncoming radar I believe.

And yes, 2002 apparently does have the capability to open/close at will. 2001 has not demonstrated that even in take off/landing, so it probably can not.

when I blow that up to its full resolution...or take it into a program and make it even larger with contrast, sharpening, lighting, brightness, and other imaging options, those do not look at all like saw tooth edges to me, Blitzo...they look more like the edges of supports within the door that you see the edges of protruding above a straight edge to the door from this angle.

I would not read too much into it however. I see these J-20s as more technology demonstrators. it is probably that details like this will come out once they build and begin testing what I could call a true production prototype.

Umm are we talking about the same area?

I'm talking about the saw tooth edges at the oncoming, "front," horizontal of the weapon bay, not the vertical, "sides".

i.e.: I'm talking about the green circle, not the red circle, which I think is what you're referring to? You can see minute saw tooth patterns against the white wall, and they are certainly not supports (it wouldn't physically make sense lol).



And I don't think there are any aircraft with weapon bay serrations going "vertically". The point of serrations are to reflect oncoming radar waves in a controlled manner, and usually they are coming from the front.

Well yeah

Thanks, Blitz, that does clarify it very well. They are definitely saw toothed on the leading edges, no doubt at all about it.

Thanks.

LOL leading edge, that was the word I was searching for.

The intakes were plugged...does that done on a technical necessity or for secrecy?

I'm thinking it's just a technical reason. We've had a straight shot down the intakes before, haven't we?

Inlets are customarily plugged once OP temps have subsided, keep birds and debris out of your hot section, even inlets of turboprops, and recips, we have seen pix of them unplugged, likely pre or post flight. For storage, inlets, pitot tubes, etc have covers, keeping out moisture, dust, bugs, birds, these covers have hanging red or orange streamers marked remove before flight. Most turbines are extremely sensitive to fod and will suck it right off the runway like a large hoover, they have sucked up a few fellers as well, not good.

Thanks, learned something...but don't anyone find the covering kinda...er, crude? Like somebody bought some insulation sponge/foam from the market and...they secure it with sticky tape? If they do that it probably this airframe have yet apply any RAM coating.

Wow, now that picture does clarify the saw-tooth edge question. Thanks Blitzo!
