The Xian Y-20 (Chinese: 运-20) is a large military transport aircraft. The project is being developed by Xi'an Aircraft Industrial Corporation and was officially launched in 2006. The official codename of the aircraft is Kunpeng, (Chinese: 鲲鹏). after the mythical bird of ancient China that can fly for thousands of kilometres. The chief designer of the Y-20 is Tang Changhong (Chinese: 唐长红).
The first Y-20 prototype is powered by four D-30 series turbofan engines and the production aircraft May be equipped with WS-20 engines, which is derived from the WS-10 turbofan engine currently powering the J-11B fighters in PLAAF. The WS-20 engine is essentially a WS-10A engine with high by pass ratio around 6.2, it produces around 132Kn of thrust and does not have the military after burning nozzle.
Cargo is loaded through a large aft ramp that accommodates rolling stock. The Y-20 incorporates a high-set wing, T-tail, rear cargo-loading assembly and heavy-duty retractable landing gear.
It was reported that the Y-20 started ground testing from December 2012, including runway taxi tests. The aircraft made its maiden flight lasting one hour on January 26, 2013. During landing in first flight, it was reported that the Y-20 prototype bounced once before finally settling on runway due to high landing speed.
In December 2013, a new Y-20 prototype took to the sky.
The Y-20 is the first cargo aircraft to use 3-D printing technology to speed up its development and to lower its manufacturing cost.
Chinese air force demand
According to Chinese sources, the Chinese air force PLAAF will need at least 300-400 Y-20 aircraft to conduct military operations in different battlefronts along the Asia-Pacific region as well as to catch up with capabilities of the U.S and Russia. This will require XAC to open two production lines and run for 10 years or 15 years.
