J-14, Fan art

I would say the guy who drew the 2nd picture is quite a talented artist who seems to have a canny sense and aptitude for aerodynamics.

He probably has a picture of a YF-23 and a Mig 1.44. It is clearly a combination of these aircraft, and his sense of aerodynamics could be so and so. I`d be very surprised if a chinese aircraft would end up looking like this

Does not look like both a YF-23 and a MiG 1.44. Wings are different and the plane lacks the inner tooth structure you see in the canard root of the MiG 1.44.

Diamond and delta wing are the best wings if you want to have the longest possible root structure to distribute the load and strain from the wings. But to have delta would mean an acute sweep, which you sacrifice low speed agility for. With a diamond wing, you can decrease sweep, improve low speed handling. What you can do is change the angle of the sweep of the wing, vary the diamond shape.

His positioning of the rudders as far backward and as wide apart as possible are the right ideas, IMO.

The picture is somewhat derived from the Chengdu yellow computer model in progress that was shown before.

These pics are a quite impressive rendering work for an amateur but they are clearly inspired by the YF-23 and some detail bits of J-10. May be the guy should send them via e-mail to Chengdu and he will probably get a job there!

Of course the real J-13/14 will have a completely different and much superior design since emulating 20 years old US projects (YF-22, YF-23 began development in 1986, first flights in 1991) is certainly no solution for PLAAF´s capability requirements for today and the near future. Perhaps PLAAF even decides to ´bypass´an entire warplane generation and introduces new UCAV´s early in the next decade?

P.S.: Are there any new chinese prototypes or technology demonstrators with stealth characteristics? Some years ago (around late ´02/ early ´03) a flurry of rumours was around and also some very dark (often monochrome) and mysterious pics of F-117 like ´things´. May be someone of our members knows more than the ignorant called myself!

these are some Jxx pic, J-13 or J-14, how do you think

Do you mean this one, Violet?

I would rather belive this will be called J-15 or J-16 something. They are only making concept right now.

@maozedong:
Yep, that is cool artwork! I think the guy should partner up with some game programmers and develop a ´China Raptor´flight simulator! (commercial success would be virtually guaranteed...)
about stealthy ´thing´pics: I remember I have seen them on site that no longer exists. The guy´s name was Rick Kamer (url: china-military or so) and he had some good info (e.g. organizational structure and history of units) on his page but suddenly he stopped updating around two years ago and after some months the site went offline. Perhaps crobato knows more about this guy??

@aikea:
Yes the pic indicates that China is working on UCAV projects but far more interesting would be whether the plane will be a ´small´demonstrator or a full blown (20-30 ts take off weight) fighting vehicle. China must succeed in mastering UAV/UCAV tech on the highest level in the coming years because these warrior birds are the decisive weapons of the future: combining superior velocity (hypersonic), stealth and high strike precision with EXPENDABILITY (no pilot at risk) enabling also kamikaze like missions against high value targets!

I don't really know what you mean by a completely different and superior design. Today, designs are no longer made by a person's intuition on aerodynamics and structural design. Its all more of computers, wind tunnel modeling, structural strength analysis and modeling, lets just say its more of computers doing the designing. Because we all face common laws of nature and physics, like in aerodynamics and radar, these common laws will force commonalities in design. Because of this, I kind of doubt that stealth fighters would look much different from each other. In fact they will all probably look alike.

As for the UCAV concept, its called the Anjian, or Black Sword.

any body pay intention in the picture what I showed above - the second pic (middle one) looks like real fighter not the model ( the back ground looks like hangar).
the plane looks like J-10 but the shape is stealthy design, I really don't know what's that.- J13?

that's a PSed picture. If you looked into some of the previous J-10 or J-xx thread, you would find that picture.

sorry,what is PSed picture? I don't know this abbreviation, maybe many people already know what dose it mean.

oh, it just means 'photoshoped' picture, which nowadays people call pictures are made by computers in general.

@tphuang: This pic (actually a series of several) has been around since last fall and it is way more than a simple ps job. This kind of graphics is a photorealistic 3-D rendering created perhaps with software like Rhinoceros 3D, POV-Ray or Cinema 4D. The whole thing is a completely virtual 3D model with highly sophisticated texture and lighting which produces a stunning perception of a real sight at first glance. At least the guy has some artistic talent and I suppose that he even applied photorealistic morphing and caustic indirect illumination which would indicate that he is quite advanced in using 3D modelling software. Perhaps more pics will surface soon probably even better than his already known works.

@crobato:
My intention was only to point out that the most advanced designs China´s aerospace industry is currently working on are not necessarily very similar to their (publicly known!) counterparts developed in the US, Russia and France. Of course physics and design procedures (organizational management, computer hardware, software) have the effect of converging the results of developmental work around the globe (much more today than 50 years ago) but differences in more than only details will certainly remain.

The concept of technological ´bypassing´is pivotal in China´s long term plans to achieve tech parity with the west and the introduction of indegenous MAGLEV trains (500 Km/h!) in 2010 on par with german and japanese tech is a convincing civil example for this strategy. Probably China will have several MAGLEV lines in operation in 2020 (perhaps a link Guangzhou-Beijing) and at this time no other country will have a comparable land transportation system in service (at least not on this scale).

P.S.: dear crobato do you know something about that Kamer guy? Why vanished the site (china-military.org or similar) suddenly?

Violet Oboe: you know so much about Jxx, any comment on this pic?
