hey thanks my burger buddy. so its roughly in between the F-16 and MiG-29’s length.
We also got a statement from the same interview regarding J-XX, in which general he weirong said:
“J-10’s max weapon load is up to six tons with 11 pylons and its shortest take-off distance is only 350 meters,”
So that’s something to add to the sketchy list.
that’s not what you said..
Note the word “Apparently”… come on…
hey I remember you.. you used to put up PS and CGs claiming it was real! and all that Russian input into CAC’s J-20, it being based on mig 1.44 etc

http://forum.keypublishing.co.uk/showpost.php?p=1665036&postcount=413and you can relax.. that’s not a tanker boom.. its just the winglet on the wing of a Russian Tupolev 😉
Similar pictures were posted at SDF and CDF… I’m not sure eagle talon was claiming those pictrues were real per se but represented what J-20 could be. Of course I can’t know seeing as I wasn’t there at the time.
Regardless, some of those CGs and pics weren’t too far off.
Thanks, I did not realize that the body of the J-20 was that wide.. assuming the F-22 and J-20 cockpit are the same size.
Here’s one of the F-35 and J-20 much more similar to each other than the F-22
I think that diagram was more directed at the multiple bumps on the F-35’s underside/sides… J-20’s much cleaner and more like F-22 than F-35 in that aspect imo.
Who, the military? Or some Lockheed marketing “guru”?
Or, did that come from engineers?
Not really.
Quite often, design tools are used to find relative improvements rather than give absolute numbers. No different here.
We don’t need the length to 4 decimal places if the wingspan is proportionally smaller, and the 1/4 chord sweep of the wing proportionally greater than the potential contemporaries.
Well I was more thinking along the lines that we cannot know how the individual features of the aircraft can interact together to affect its performance as a whole.
The fact that some conclusions people have come to on J-20 are very different to what we’ve been getting from official and semi-official sources makes me think either CAC don’t know what they’re doing, the PLAAF and big shrimps are trolling us, or there is something people are missing on the analysis being done.
But don’t stop on the account of me, it makes for interesting reading.
Do you know what finness ratio is?
If you wanna wait for some Chinese general to tell you what the width:length ratio is, fine. Meanwhile the rest of us will go ahead and examine the thing.
The fuselage is large. The fuselage is very large in comparison to the wings. That means plenty of space for sensors, weapons, avionics, engines, the pilot… and fuel.
The sensors will not be any larger than those on comparable aircraft, nor will the avionics. Pilots are roughly the same size.
Leaving volume for weapons and fuel.
Hmmm…..
:rolleyes:
Or how about listen to experienced professionals.
The same professionals that said it would take China well beyond 2020 to field its first stealth fighter?
Assuming you mean engineers… see below
I don’t care if we’ve heard nothing.
In fact – I wouldn’t care if their top general came out and said exactly that.
You cannot get past the laws of physics, the same ones apply in the USA, Russian and China.
Unless you have some knowledge and information about this aircraft beyond what we know then extrapolating a role from eyeballing the physics while most people can still not agree on its length seems a little strange no?
But whatever, I see people are more interested in debating what it could be rather than settle on what it is.
I think many people beleive that is a PS because all the small and fairly thin looking trees are still standing upright while the uav looks perfectly intact.
And btw the second photo they show is not the BZK-005
Regretably, almost all of such measurements based on very low quality photo.
By GE photo you can even get 19 meter more or less.
the estimates based off the truck and trailer photos, as well as pinko’s runway comparison with J-20 and J-10 all gives J-20s length as between 20-21m, leaning towards 20m which is better than any other method of estimate we’ve had.
I agree the GE photo is not very clear, so I wouldn’t base anything off that.
Working off 20.5m?
There was mention of F-22 and J-20’s wing areas in posts 62 to 65 of this thread… zzz
Hmmm .. Yes, but why a Tu-204 as a testbed !??
Since the PLAAF and PLANAF only used the house&drouge system a new pod could be tested simply on one of the standard HU-6 or even Il-76 … and a refuelling boom is IMO unlikely !?
Deino
Well huitong did mention J-20 could be getting a boom style receptacle… I’m more interested in what kind of tanker will replace or supplement the wearied H-6Us. Personally I’m hoping PLAAF took the extra step to consider giving all their Y-20s the capability to act as a tanker/transport like the A400M and KC-390, while having dedicated Y-20 tankers as the mainstay.
The fuel fraction of the J-20, coupled with its large finesse ratio, means it is a design built for speed over maneuverability.
That does not mean it cannot maneuvre, but it does mean some sacrifices have been made to what the maneuverability could have been to benefit speed and range.
Hence why I see it as an interceptor/interdictor more than an aircraft bred for dogfighting.
I see eyeballing the aerodynamics and even internals of an aircraft and then deducing its role as rather misguided. Better to get information from official sources at best, and if that’s unavailable, then credible rumours.
The problem is we’ve heard nothing coming from the chinese side about compromising manouverability for speed or range, if anything manouverability seems to have been listed as one of the most demanding aspects of the plane.
Clearly we’ll have to agree to disagree.
Actually in the pictures eagle talon posted it looks like the air china livery has been removed… or PSed off? o.O
To make the most out of it, they should take a look at the JDRADM concept
Quite a few new long range BVRAAMs with small diameters seem to be under development… there was some speculation one of them could act as an ARM like the JDRADM as well, which would certainly be useful.
There will not be anymore(your words) ‘dedicaded Interceptor’ ever again.
The last one is the Mig-31, not sure about the F-22 though(it has poor range)..
The Flanker design is not a dedicated interceptor, but its classify as an heavy Interceptor, even if it has other great performance too!It has something to do with Internal fuel capasity, speed, weapons load and a powerfull radar(sensors) first and formost.
All these transform into a larger airframe design then the ussual fighter design.
Yet as a Interceptor the Flanker is a air superiority with multirole capability too.
I’m sure the J-20 will have some multirole capability.I did not say ‘dedicated Interceptor’.. you did..:rolleyes:
I’m not sure where we disagree, we both agree there was no dedicated interceptor developed beyond the Mig-31 (unless SAC’s still whipping the J-8 lol), we both agree large fighters can act as interceptors and aircraft like F-22 J-20 and Su-27 can fill that role as well.
Yes I did say “dedicated interceptor” and you didn’t seem to get that when you made reference to my post in your reply 221
The J-20 is a heavy Interceptor class aircraft, now deal with it!
The problem is semantics I suppose. Would you consider F-22, Su-35S and T-50 to be heavy interceptor aircraft? If so then fine. Personally I classify them as heavy air superiority aircraft with multirole capability.
Not sure why you are so touchy with my reponses..
The term interceptor specifically refers to dedicated interceptors like the F-106, MiG-31, etc. By definition they are highly specialized aircraft. The Flankers, Eagles, and Raptors are air supremacy fighters. Although they are capable of the interceptor role they are not called interceptors.
Now that nomenclature is established, I propose we move on.
+1
Basically what I’ve been trying to say this whole time.
You sure the J-20 has multirole capability? Then define what does multirole mean in your way……
Does carrying few bombs or a2g missiles can be multirole?
Indeed. F-22 can carry JDAMs and SDB, does that make it “multirole” when other aircraft like JSF can also be considered that?
The point is you cannot create lower cost mulitrole fighter. There arent any methods to lower cost if your designing and certifying a new plane. unless it is something modest. keeping a different assembly line by itself is costly.
Of course we’re talking about J-19 relative to J-20… production methods, materials, avionics could all less advanced and capable
Head of COMIC resign after 3 years and took job that is completely unrelated to aviation field. so you have to look at appointments how he got there at first place. . Putting 4S ability into J-20 is not going to happen in current form. Airplane frontal is simply too deep & wide.
Yeah well that’s your opinion, or maybe your hope.
J-20 the pilot head is only visible and side profile is like recantgular box. It will have big weight and drag penalty. and will have very short range. much shorter than F-22 that your claiming J-20 is intended to compete with longer range. I am not even going into that longer landing gear & extra weight of canards.
http://s4.hubimg.com/u/4446655_f520.jpgYou can clearly see pilot shoulder. with frontal cut out to make it sleek untill the engine bay. so there is degree of confidence it will have longer range and higher cruising speed.

Yet you’re still trying to eyeball size… not to mention that, even the aircraft’s drag…
I’m done here.
