    The Y-20: China Aviation Milestone Means New Power Projection

    Escorted by a J-15 fighter and numbered “20001,” China’s domestically-produced Y-20 transport aircraft successfully completed its maiden flight on Jan. 26 at the People’s Liberation Army Air Force (PLAAF)’s China Flight Test Establishment in Sha’anxi province, remaining airborne for an hour , according to state-run media reports. In an example of selective transparency to boost pride at home and credibility abroad, domestic media were rapidly notified of the Y-20’s test flight (see CCTV broadcast here and here) and Chinese military enthusiasts are energetically welcoming the news.

    I don't know the specs on those engines, but visually, they appear to be more straight jet than turbofan. Note how narrow the engines are compared to a high-bypass fan... much like the early 737's.

    China has made great strides in aerospace, yet the lack of a true native turbine engine industry is holding them back.

    They look like JT8Ds.

    Edit: According to the article they're D30-KP2 engines, which are about the same thrust but are bigger and heavier.

    Yeah, they DO look like low bypass-ratio turbofans, as opposed to high bypass-ratio fans.

    With the exception of the nose, it looks almost identical to the Il-76. Plus, it uses the same engine as the older Ilyushins. Looks to me as a locally produced version of the Il-76, much like what was done with the J-11.

    The real voyage of discovery consists not in seeking new lands but seeing with new eyes.

    The Tail and Cargo bay area looks extremely similar to C-17A and Wings are an exact replica of the IL-76, with the older D-30 Engines, not the new PS-90A engines which as far as I know Russia will not sell to China ( not sure) and front section reminds me of a Airbus. The Landing Gear area is an exact replica of the A-400M

    The writers are professors from the US naval college and leading experts on China defense, they know what they are talking about.


    The Y-20 differs clearly from other heavy transport aircraft like Russia’s Il-76, America’s C-5 and C-17, and Europe’s A400M in fuselage shape, wheels and flap actuators. PLA experts quoted in a story appearing on the English-language website of the People’s Daily claim that the Y-20 outperforms Russia’s Il-76 and say it boasts “Chinese characteristics in supercritical airfoils, integrated avionics, cabin equipment, composite materials and their processing.” The experts say the plane has three aircrew, a 15-meter height and 47-meter fuselage length, a 66-ton maximum load capacity and a maximum takeoff weight of just over 200 tons. Its capacious cargo hold can “carry the vast majority of combat and support vehicles of the Chinese People’s Liberation Army (PLA),” including the PLA’s heaviest tank, the 58-ton Type-99A2. It can transport them even to underdeveloped “airstrips” thanks to its “strong adaptability to [substandard] take-off and landing fields.” This suggests the PLA has carefully noted the ability of the U.S. C-17 to land on rough dirt airstrips and serve forward combat bases in Afghanistan.

    Very tangential...

    It mentions Ukraine in the 4 producers of these types of planes. Have they done anything worthwhile in the field after the break up of the former union?

    Antonov hails from Ukraine. So the world's heaviest transport aircraft ever built (An-225) belongs to Ukraine. As for more recent projects there's the An-70, as well as some jet liners.

    Both are Soviet-era designs. I was more interested in the engines development as clearly the know-how for other aspects is in Ukraine.

    For instance can the Chinese acquire tech from Ivchenko-Progress bureau or they are outdated?

    That's not hard to do; the Il-76 is a 45-year old design.
