does anyone (kind and altruistic) have original AVIC I promo video from 2006 with their early Y-X concept?

Yes, it was the early design concept of the Y-20, but the real Y-20 looks very different isnt it ?

I was very suprised by the advanced shapes, and technologies of the actual Y-20. Before, I thought it will look like IL-76. Just like J-20 will look like PAK-FA. But Chinese military tech have came so far that I can no longer under estimate them. :eek:

Well, at least externally it doesn't make a frog leap from this concept. It's hard to say what wing was at the beginning.
Forward fuselage refined and wing box was moved up to save volume for cargo bay, that actually has almost the same size as An-70 (at least if we trust 603 Institute guys article) while fuselage diameter went down 100 mm less than An-70.
I'm not sure about cargo floor length, its about 20-21 m according to my calculations, that can hold 3 ZBD003 on platforms.
Who were the parents of tail section you'd probably know...fuselage structure is quite conservative compared to An-70 that use much more composites. Guess that T-tail consoles are metal with composite rudders and fairings.
Anyway, it looks quite balanced and aesthetically appealing design. With new engines it will look even better. Rather disturbing is low pace of flight tests. Huitong reported that 20-002 was rolled out in May, but on some reasons didn't fly yet.
I expect guys have some structural problems, remembering these tail tremors on quite an accurate touchdown. Well, Tong was cautious talking of test period saying of 5 years. Even in this case, compared to FLA/A400, it's quite a good temps.

I'm quite sure that MBT transportation was in RFI, but hardly can imagine where you gonna fly them after reading PLAAF White Book))

T-tail always flex in a touch down and T/R deployment.. always. especially for t-tails designed to the minimizing aeroloads.

most of time T-tails designs loads bending at touch down simply do not factor into design... my last two airplanes being T-tails...

they are designed to flex a bit anyways. in air the maximum loads that the tail is designed to is much more then loads at touchdown.

Lots of these capital projects have slowed down in China at the present Eric, I would posit that much of this is likely new regime/financial in nature. As i.e. has noted all aircraft structures, particularly large heavy lift aircraft exhibit a very high degree of aero-elasticity, think of it as a shock absorber for the airframe to protect it from catastrophic failure, so the tail wagging back and forth or side to side, is as normal as the wings flexing up and down in turbulence, it is much less obvious, and it certainly is not as limber as the wing, but it is there just the same.. Now having said that, with any new clean sheet design, there will be issues, which must be confronted and rectified, but we have no certain knowledge of ANY such issues with the Y-20. brat

and I will add the Y-20 appears to be quite robust and lovely to look at..

...where exactly PLAAF need to move their MBTs with such a speed? that comes with a [high] price

I'd say a lot of it is just keeping up with the Jones's as they say here in the US, China sees the world standard for Airlift, and realizes that is a very important capability if you want to be taken seriously, the US has had an exceptional airlift capability that has enabled us to move equipment around the world, as you correctly note it is expensive, and our current sequestration is killing the US military. The Socialist Welfare State that we have become is eating our productivity alive and the people who have become dependant on the US gov for their care and feeding are continuing to multiply like rabbits. Even our own president has set an example of exceptional consumption and disregard for the state of the American economy and the family's who have worked so hard. not good brat

Tibet and Xinjiang? If China doesn't want to forward deploy equipments at the border regions (and tied down significant amount and expensive items) and risk having large amount of obsolete equipments.

What percentage of the transport production ( ton km or for Americans ton miles ) of US aircraft capable of lugging tanks about ( C-5, C-17, any others? ) is actually transporting tanks?

Regarding that old contract !!

【环球网报道 记者 胥文琦】据俄罗斯军工网6月17日消息，俄罗斯国防出口公司空军特种物资和服务出口部主任谢尔盖 科尔涅夫表示，俄方将向中国空军提供十架伊尔-76MD军事运输机。

　　他在接受媒体采访时说：“根据2011年我们签署的合同，2013年至2015年期间将向中国提供俄空军现存的10架伊尔-76MD飞机。”同时，根据合同俄方将对中国人民解放军空军拥有的部分伊尔-76MD飞机进行维修。

　　正在率团参加法国巴黎国际航展的科尔涅夫还继续指出，该份合同如期执行。
