AESA or not AESA … tha’s the question ?! 😉

Amazing, I think we’ve never even seen the j-10a’s radar and now we see he j-10b’s before it even enters service…

I’m quite certain it’s ESA if not aesa because it has that thick and canter look instead of the thin “plate on an arm” so common with mechanically steered arrays.

You mean ps a J20 into that vivid natural surrounding includes that hot air flux ? No way !

Thanks!

that picture just looked a bit too awesome to be true 😀

Perhaps we have different definitions of weapons bay then. But from this image i’d say it is impossible f22 has bomb bays much over a meter across, two meters for both bays in total.

I dunno… Two meters just seems way too small for me… There’s gotta be a drawing of the f 22 with the dimensions of the weapon bays somewhere on the net.

Just did some quick calculations…
the diameter of the PL-12 is 0.203m and overall diameter+wingspan is 0.67m. If they are emplaced roughly like so:

Then the total distance width required will be 3.086 meters.

Here’s my calculations:
Actual wingspan (i.e.: width of two wings ) = “wingspan” – diameter of missile = (0.67m – 0.203m)
Divide by two to find width of one of the actual “wings”, i.e.: the distance “X” which is the distance that will be between each of the missiles (without clearance)
That gives (0.67-0.203)/2 = 0.2335 meters
then add up all the distances.
4 x “distance X” + 3 x “diameter of missile” = length (or width, I suppose) needed to hold three PL-12s.
4 x 0.2335 + 0.203 x 3 = 1.543 meters
Times that by two = total width for six missiles necessary
2 x 1.543 = 3.086 meters

Now assuming there would need to be some clearance between the PL-12s and the “walls” of the weapon bay and between the PL-12s themselves… let’s pretend the clearance distance necessary is five centimeters (0.05 meters), then we get…

previous “total distance” + 8 x “clearance distance” = total distance + clearance required

3.086 + 8 x 0.05 = 3.486

Now the F-22’s weapon bay width is about 3.9 meters (?) but I’m not sure if that’s the actual width or the width with the levers and doors in addition.

Either way, seeing as J-20 has similar if not slightly larger dimensions compared to the F-22 I think six PL-12’s in the ventral bay should be quite possible.

I winged this quick type up btw, so I might have overlooked some obvious arithmetic, if so please make your own additions and give an opinion? If anyone can estimate a width of the J-20’s underside fuselage that would be helpful too.

Cheers.

That looks about right, I think 20 meters is a good estimate. Bigger than the F-22 but not so much that it’s an F-111 equipvalent. Similar in size to T-50, with the latter longer from its tail sting.

I wonder if the J-20 has a longer ventral bay because even though it’s only longer by a meter, the engines relative to the plane is placed a good meter or two back compared to the F-22.

Who told you a shoter airplane is a good dog fighter? The Su-27 is much longer than MiG-23, will you say the MiG-23 will win Su-27 in high probabality when they perform a dog fight? Otherwise, J-29 is shorter enough than F-22, who will you bet to be a winner in a dog fight?

Conversely I saw someone lacking confidence of sufficient power to the J-20. The J-20 supposed to be a small jet to adapt their weak engine:cool: If this is not true, then a large jet with powerfule turbo means a capability for multi-function.

From the 3D picture which did magnificently, no less six MRAAM should be loaded in ventral bay. In terms of typical MRAAM PLA used, even stagger arrangement considered, the weapon bay ought to be more than 2.1 meter wide. But the F-111’s only weapon bay is supposed to be 1.2 to 1.5 meter wide for two AGM-69 loaded parallely. Which means the weapon bay’s wide of J-20 are supposed to be at least 1/2 larger than F-111’s on wide.

Submit to you guys, I constrained the size to 20.5~21 meter below, then I wonder how can you sqreeze 6 PL-12 or PL-11 into such birdcage?

Six PL-12Cs with the folding rear wings should be able to fit in no problem.

I doubt PL-11s will be used on the J-20.

They’d have a harder time fitting in six normal sized PL-12s or the future PL-21 in but I think it’s possible, without going into detailed analysis.

Unguided rockets on a stealth bomber??? Cluster bombs would be more effective.

PLAAF tradition :p

Just some light hearted entertainment. Please don’t take it seriously 😀

(I’m not saying T-50’s a rip off of the F-22 or J-20 will own F-22 or that Gates is stupid… Chill guys 🙂 )
