  • The Y-20

    It is very similar to the C-17...don't you think? Several years ago, the blueprints of the C-17 were stolen by spies working for Boeing and given to China.

    Now...if only they could reverse engineer the engines. Eventually, they should figure it out...it's just a matter of time.



    Satellites Spot China’s Mysterious New Warplane


    The Y-20 at Yanliang on Jan. 1. Photo: GeoEye GeoEye 1

    A week after the publication of blurry photographs depicting what appears to be China’s first long-range jet transport, Danger Room has obtained satellite imagery of the new plane at an airfield in central China.
    The images, acquired by the GeoEye 1 and IKONOS spacecraft — both belonging to commercial satellite operator GeoEye headquartered in Washington, D.C. — corroborate the general layout of the Xian Aircraft Corporation Y-20, the existence of which has been confirmed by Beijing.
    The IKONOS image (below) is dated Dec. 25. It shows the Y-20 outside a large hangar at Yanliang airfield, home of the People’s Liberation Army Air Force’s test establishment. The base is crowded with examples of the PLAAF’s other main transports, including Y-8 medium airlifters and, apparently, tanker versions of the aged H-6 bomber — both types of which could in theory be replaced by the Y-20, ostensibly giving China the same global military reach the U.S. and other advanced nations have enjoyed for half a century.
    The GeoEye 1 photo from Jan. 1 (above) depicts the new transport, which isn’t known to have flown yet, on one of Yanliang’s runways, surrounded by people and vehicles. News reports have claimed the Y-20 is currently undergoing runway taxi tests in preparation for its eventual first flight.



    But even after that happens, the Y-20 will probably need lots of work. Indeed, when it comes to jet-transport technology Beijing is “falling behind, not catching up,” John Pike, an analyst with the Virginia-based Globalstrategy.org, writes in an e-mail to Danger Room.
    Specifically, the Y-20 needs new engines — and there’s little evidence that Beijing is making much progress on that front. The prototype is reportedly fitted with old, Russian-made D-30 engines that probably aren’t adequate for the Y-20′s design.

    I'm still very curious why china is having a hard time with engines?

      The resemblance to the C-17 may or may not be the result of espionage. The fact is, there are only a number of logical ways to do a military cargo plane. Most US and Soviet/Russian designs seem to share the same basic layout with only some variation in tail assemblies and the addition of new drag reduction features in succeeding models.

      As noted, the engines are the challenging part and we can't tell much about those from the overhead photos. That along with the associated avionics technologies would be the data most worth stealing.
      Any metaphor will tear if stretched over too much reality.

        Wouldn't the plans to build a C-17 take a large 18 wheeler to transport?

          This is how they test rocket engines ....scary if you ask me.

            I dunno, Perse, it looks pretty much like a typical rocket motor test to me. Not even very spectacular really. Google 'Santa Susana Field Lab rocket tests' and you'll find pretty much imagery that looks exactly the same. Look for Saturn V F1 engine tests, they'll look very similar and even more specatacular.

            Here's a nice one, with some really nice footage of the gimbal testing of the F1s. Note the center engine which is fixed in place :



            In the beginning of your video, the guys taping start talking about how the water is starting to come down. The water is used to cool the flame jet so it doesn't burn up the concrete. I don't know the size of the motor they're testing, looks pretty big, probably close to the F1 or RD170/180. Maybe it's the new engine they're planning on using for their moon program? Still not a F1 or F1A.
            At SSFL, when they used to test in the '60s and '70s extensively, we could hear the motors about 20 miles away in the San Fernando Valley. It was pretty impressive and if you lived closer in Chatsworth, for instance, and were up a little in the hills, you could see the glow from the engines. Mostly that was when the F1s were being fired off, I think. Rocketdyne is just down the street from SSFL; AI (Atomics International) North Americans nuclear division was a couple of miles away from there. They tested up there as well and that stuff was much scarier and still is due to the nuclear radiation effects.

              Why invest billions in R&D when you can just steal the plans? That is the entire basis of the current Chinese economy and technology - steal it from the West.

                Why wasting billions in R&D to reinvent the wheel?

                  And I wonder why exactly D-30 engines are not adequate.Those are very powerful engines.

                    Power is not the issue; fuel consumption is. The D-30 is a low-bypass turbofan engine originally designed to power supersonic fighters. Even in its commercial form, the D30KU, it is not very efficient. The C-17 uses high-bypass turbofan engines which are much more efficient at subsonic speeds.

                        True...but the Chinese test lab appears to be in very close proximity to some office buildings. Then on the outer perimeter, there are trees for as far as the eye can see.
                        I think I'll stand by my statement that it is "scary" .


                        Below is a test at Santa Susana Field lab...looks safe enough.






                        And below is the Chinese engine test....

                          Perhaps...it's a IL-76 clone? The Chinese military has numerous IL-76 in service. They could have incorporated some elements of the C-17...very do-able.

                            didn't china try to clone the Il-76?
