    I’ve learned to become skeptical to some of Huitong’s entries just as much as others.

    Although YJ-12 is somewhat smaller than say, Brahmos, and it can achieve the same speed and range (depending on profile) so that satisfies the idea that elapsed time and advancements in propulsion, propellant, aerodynamics etc would lead to similar performance in a smaller package.

    Hui Tong puts it between Kh-31 and Kh-41 in terms of size. Mach 2.5 – 3.5, 150 – 300 km depending on flight profile.

    So its less than the early speculation of 400 km @ Mach 4, but high time this thing has showed up. Otherwise PLAN ASCM were limited to YJ-62, YJ-83 series.

    Interesting that he puts that as the specs. It was heavily circulated that YJ-12 was known as the “4, 4” missile, as in Mach 4 speed and 400 km range… Hmmmmm. I also doubt that J-15 can only carry one when JH-7B can carry two, even though the flanker is a far better strike platform. Interesting that he doesn’t mention J-16 either, I’d imagine J-16/15 should’ve at least be able to carry three.

    look at that long long bottom bay.. looks like its long enough to carry some heavy, large, well endowed missile.

    I’ll be surprised if it can carry anything bigger than a 450 kg smart bomb like the F-22. It definitely ain’t long or deep enough to carry even a rudimentary air to surface missile like KD-88 even if it had folding wings.

    “γ€€The Y-20 not only outperforms Il-76”

    I am not the one flaming.
    This chest-beating article on the other hand….

    It’s quite rare to get such relatively official specs on such an important plane still under early development.

    Don’t take it as an affront to the Il-76. Considering Il-76MD has been the PLA’s only large transport for so many years past, the fact that they’re on the way to develop a successor with greater performance should be worth pointing out (and they do mention the engine deficiency of D-30 vs PS-90)

    The phrasing could be better and it’s obviously aimed to instill some level of pride (it’s in the china youth daily for crying out loud. “carries dreams and expectations of millions of chinese people”…), but that doesn’t make the numbers any less valid at this stage.
    Although it’s interesting we’re getting this from 2nd Arty rather than say, the air force.

    EDIT: Is the purported payload based on current D30 engines or is it the design payload for ‘final’ engines?

    That’s the big question isn’t it? I think Y-20 will be hard pressed to haul 66 tons with D30s, unless they significantly sacrifice short take off performance.

    The most striking feature is the all moving tail surfaces that are so similar to the Sukhoi layout and functions.

    The only similarity between the J-20 and T-50 tails are that they are “all moving”… the shape of the tail, the point where the tail actually rotates (and the front root of the tail which doesn’t rotate!) is completely different. J-20’s all moving tail actually more resembles F-117’s configuration.

    Incidentally, T-50’s all moving tail mechanism more resembles YF-23’s… not implying anyone of copying anyone else, of course.

    Except the J-20 uses a chute, and has an air brake, and we’ve never seen the J-20 deflect its canards to brake before? I suppose it could be for specific circumstances, like if there’s a high approaching speed or if the chute fails…

    Have we ever seen J-20 use its airbrake to brake before? :confused:

    I think we’ve seen the all moving tails act as airbrakes during landing, but I’ve yet to see the massive dedicated airbrake in use before..

    From what I’ve heard YJ-12 is only high supersonic.

    have u looked at the tail of plane. It looks bigger than the plane. I can predict the plane will end up to be overweight/draggrier/low operational speed & altitude with short life span and will unable to fullfill most of mission requirements.

    All T tail transports look to have massive tails.

    And I like how you can infer all of that with a glance at a photo, maybe all aerospace companies should hire you to give their designs a once over seeing as you seem to know whether a plane will fly the way they want via eyeballing.

    and IL-476 has delivery schedule of 103 planes before 2021. Not orders.

    In case you didn’t read my post, the end point was that Y-20 probably won’t be challenging Il-476 for export orders any time soon. So I’m not sure why you’re suddenly so testy.

    Btw Y-20s seemingly unwieldy tail is likely an effect of angle and the generally low resolution of the picture.
    We haven’t got a decent side picture yet, and this CG is the closest thing we got (most likely made by someone who was actually there to give us a teasuer of the eventual real high res photos that inevitably must have been taken)
    If this is accurate at all clearly its tail is not as large as you believe, at least it looks proportionally sized with the likes of C-17, Il-76 and A400M (not to mention C-2, which also has a massive tail)

    As much as his usual drivel is nonsense, he actually does (accidentally, no doubt) hit the nail on the head here. It is hard to tell from such poor quality photographs, but it looks like the fuselage cross section (and therefore cargo hold dimensions) are significantly larger than on the Il-476, perhaps based on the An-70. Similarly, I would be very surprised to learn that they did not put a supercritical wing on it, given how much of a departure from the Il-76 it obviously represents. All in all, that would mean (barring unforeseen design defects) that the obsolete engines are the ONLY thing preventing this aircraft from completely outclassing the Il-476 – and we all know it’s a matter of when, not if, the power plants will change.

    The frustrating thing about this (from a Russian perspective) is that putting themselves into this position was wholly unnecessary – a combination of An-70s and An-124s renders the Il-476 completely redundant. Not to mention that Ilyushin would have been perfectly capable of designing a competitive airframe – they deliberately chose not to and will now possibly have to bear the consequences (irrelevance on the export market). A colossal waste of time, money and talent.

    Fortunately for the Russians, it will be a while before Y-20 finishes testing, not to mention the new high bypass WS-10, (I doubt the Russians will allow Y-20 to be exported with their engines) as well as the (hopefully) large order of this plane which the PLA places with hXAC probably unable to keep up a high production rate for both internal and external demand.

    But in terms of the maximum achievable performance for Y-20 in the most important aspect for transporters (carrying capacity), it appears that it’s fuselage is larger and wider than that of Il-76 and engines for the moment will be the only limitation

    Okay, to bring the thread away from the superhornet…

    over on SDF user no_name posted an excellent translation of an article documenting the various take off weights, profiles under various headwind and engine availability conditions, of Su-33/J-15 from Kuznetsov/Liaoning (post 417)

    http://www.sinodefenceforum.com/navy/plan-carrier-operations-news-videos-photos-ii-28-6173.html

    Basically for the lazy, at 25knots headwind (which is more or less the standard speed a CVBG operates at), Su-33/J-15 can take off with 32.8 tons from all launch positions.

    So really, it seems like ski jump is not as big a limitation wrt TOW as thought, if this is right (and it passes my smell test, you don’t just make those numbers up in your head).

    Certainly it is the most comprehensive article detailing the use of Su-33 on ski jumps I’ve ever come across. I’ve always thought the “ski jumps = small payload” stereotype was a little too straight forward, and this seems to clarify things greatly and makes the benefits of catapult vs ski jump much less of a black white matter.

    Thoughts, opinions, responses?

    I agree. far better looking than the ugly J-20.

    I don’t know what you’re talking about :p

    A question…what is the likelihood of J-20/J-31 making a guest/mock-up visit at Zuhahi?

    Zero, unfortunately. J-10 only made its first appearance after it received IOC and was “declassified” in mid 2000s.
    The best we can garner from zhuhai are some cockpit and smart bomb mock ups and models of some interesting UAV projects.

    Well, that settles is then …probably they were working on 2002 ever since the rumour about it leaving to Yangliang.:)

    Well we’ve had pictures of 2002 come out after the rumour it was at yanliang…

    Anyway, I’m interested for closer up shots of the nose. There was definitely some work done there, apart from the radome (and yes I am talking about the EODAS )

    Nope~When U check the pic of 2001, you will find out that the color changed again and again!

    sometimes it look like gray

    sometimes it look like green
    [ATTACH]209160[/ATTACH]

    I have not noticed any different paint differences in the pictures you posted nor any other pictures I’ve seen, apart from the change in 2002’s radome colour from black to grey (and it has yet to be determined if that is the same 2002 we’ve seen for the last few months or if they’ve built another prototype with the same designation).
