    It’s not impossible they’re testing RAM already on the first prototype but I think they chose the black scheme cause it looks badass and chengdu are putting some pride into their work. The WZ-10 is painted a similar colour.

    I don’t think we’ll see “impressive” performance by the prototypes any time soon. Partly because that will prolly not be done at the current facility, and if it were, plane spotters on the ground won’t be able to catch the plane at the altitudes they’ll be at.
    If we’re lucky we’ll see it at 2018 zhuhai once it’s got IOC, or maybe we’ll get test footage when they have an eventual CCTV documentary.

    Not as bold as the “berkut” but very different from F-22/JSF considering allegations of espionage from those programs. Most people were surprised because it wasn’t a direct rip off.

    I am curious as to how much they data obtained on the JSF and maybe F-22. Probably not enough to build a decent aircraft/rip off from them though — I don’t think that many people were surprised it wasn’t a copy, seeing as how hard it would be to clone (hey, some people still say the plane has aspects stolen from F-22, F-35, and even Mig-25 so taht’s something 😀 )

    In all seriousness though, I don’t think many people were expecting the aircraft to look so complete and with seemingly impressive attention to detail.

    And FWIW i rate this design above the PAK-FA for its boldness…..:eek:

    Careful 😮

    while we are both guessing on the reasons behind the choice.. i think we both agree the decision may have been a compromise.

    but how negligible is this RCS increase? the French and older US aircraft like the A-6 claimed fixed refueling probes had negligible effects on RCS.. yet we don’t see them being used on stealth aircraft.

    I suppose it would be considered negligible relative to the usual RCS of that generation of aircraft?

    Once those Leading edge slats droop your nice planeform alignment is gone, same goes for those Flaperons.

    May be, just may be in some of these stealth planes there is a “Stealth Mode” in the FCS.

    there is more than one way to balance out the pitching moment you know… and when RCS is your biggest requirement you are not likely to be 1) at low speed and 2) need large surface deflections…isn’t it?

    I can’t say anything more.

    Um kay, not really sure about relevance to my post tho :-/

    one thing is that the J-20’s canard is angled upwards, very different angle and plane from the main wing
    http://static.rcgroups.net/forums/attachments/8/3/1/0/7/t3741425-189-thumb-J-20%20Front%20Profile.JPG

    but the US X-36 canards are at the same plane and angle as the main wing
    http://www.dfrc.nasa.gov/gallery/graphics/X-36/Medium/EG-0096-01.gif

    so too was the Lockheed JAST
    http://www.jsf.mil/images/gallery/cddr/lockheed/cddr_loc_006.jpg

    i guess the J-20’s canards are more akin to Rafale and MiG 1.44
    http://media.moddb.com/images/groups/1/3/2044/1.44_02.jpg

    I suppose being on the same plane, but angled slightly must be a compromise between the X-36’s and J-10s canard placement.
    As latenlazy said in the J-20 thread, i too believe the canards likely produce a negligible RCS increase over a conventional placement.

    Also, in terms of planform alignment would an angle to the canards effect anything? Because the radar waves should still be scattered in a controlled fashion in the same direction as the wings? Acting in the same way the F-22’s V tails leading edge is aligned and therefore scatters as the main wing’s leading edge.

    At least one.
    One flyable prototype 2001, and very likely a static test frame 2002. There were eyewitnesses and a few dubious photos which claimed there was another flyable prototype designated 2001 but there’s no definitive of that yet.

    Maybe the Indian side should join KAI’s KF-X instead :p

    why not? they have models of other foreign aircraft alread

    Yeah, but of aircraft which are not just a few models seen at airshows.

    only degrading if you have too much senseless pride.

    If you don’t find it degrading that they’re testing a model of an aircraft which we’ve only seen a few models of, that’s fine. But you have to admit at least it’s a bit illogical.
    There were two other candidates to test which resembled the model in the picture before the AMCA.

    And if it wasn’t degrading it was certainly flammable (I’m assuming unintentional).

    check out this wind tunnel model from Russia. looks quite alike the YF-22 (unlike the supposed J-16 model above).. and the Raptor’s design has changed since then
    http://paralay.com/t50/m101.jpg

    Are you implying that because the Russians were testing a wind tunnel model of a prototype US fighter years ago it would be logical for China to do something similar?
    The difference is that if the picture we saw was of testing the AMCA (lulz), they’re basing iton a few models seen at airshows. The Russians had a real flyable plane to work off (depending on when the picture was taken).
    IF that is a model of the YF-22 in the first place.

    that was a sub-comment, placed underneath my first comment in which i said it looks like the AMCA. and sure there could be a possibility that Chinese engineers have wind tunnel models of non-Chinese aircraft.
    Did you know there’s pictures of Chinese Rafale and F-16 wind tunnel models?
    I bet you didn’t know that.. and no, they’re not models of a new potential Rafale clone. As I.E said, its just foreign technology analysis work, and there could be a small possibility that China wants to examine what India is trying to propose.. Don’t under estimate China.. they examine carefully the technologies of other countries.

    Sure, but I think maybe the implication that the engineers would be so gullible to perform wind tunnel tests of an aircraft that won’t fly for a while, while still in the fairly early development stage and might still require redesign in future, was a bit degrading.
    If anything it would’ve been more logical to say they were studying an F-22 or ATD-X wind tunnel model seeing as they are closer to reality than AMCA while they all look similar.

    but whatevs.

    Yes, the best reference of what will the J 16 look like, from the open source with long history :p

    http://img.photobucket.com/albums/v487/sharky221/J-XX_wind_tunnel_model2.jpg

    This is to be one of the failed Jxx design by SAC. It used to be the standard Jxx picture about half decade ago.

    Ah good times, back when J-10 was considered the “new generation fighter”.

    And who can forget this drawing? Turned out to be pretty damn accurate too

    come to think of it.. it looks alot like the recent HAL AMCA model

    http://1.bp.blogspot.com/_o_no4M2xEPY/TVJO49FdmFI/AAAAAAAAMdg/6V9pduDPT4c/s400/DSC07232-779279.JPG

    perhaps its Chinese engineers examining a potential adversary.

    I somehow doubt that.
    The model is so blurry it’s more likely if they were examining an adversary it’d be the F-22 rather than AMCA, which I class as a very, very distant potential adversary.

    The J designations from 16 to 19 are all very confusing, and all SAC projects supposedly.

    Apparently this “J-16” is based off one of SAC’s failed J-XX proposal… but I had thought J-16 was the J-11BS strike variant. Zzzzz
