Reading with last orders for engines D-30KP2, 54 2017 -2020 + 170 after China have enough for 40 Y-20 a 1st batch others for Il-76 after possible they build her own WS-18 or 20.
New civil variant Y20F-100 more long of 7 3 m to 54 m the rest identical

On the side line of national congress the chief engineer of Y 20 said they will equipped Y 20 with domestic engine the earliest 2018. Sofar feedback from PLAAF is positive There is nothing about broken shaft .Seem everything is on schedule
Equation I give you a run for this picture what a beaut

The Chinese military transport aircraft Y-20 will soon acquire a native engine, its chief engineer said on Friday, March 10. TANG Zhang Hong (长 红 红), also a member of the Political Consultative Conference, is currently attending the 5th session of the 12th National People's Congress in Beijing and in an interview with the local media.
TANG, chief engineer of the Y-20 program.
"The Y-20 is still in the operational testing phase," TANG told reporters at Huaxi City Daily , "the first operational feedback shows that customers are very satisfied. "
The first two Y-20s, registered 11051 and 11052, were delivered to the Chinese Air Force on June 15, 2016 and were admitted to active duty a few weeks later in the 4th Transport Division based at Qionglai in The province of Sichuan.
This is the first time the Chinese Air Force has a locally designed 200-ton transport aircraft, with the sole "regret" that the aircraft is still equipped with a Russian D-30KP-2 engine , For lack of the Chinese equivalent.
The chief engineer of Y-20 specifies for this the schedule of the Chinese engine replacement: "You will see Y-20 equipped with Chinese engine next year (2018) or the year after. Without indicating the exact time of this.
A Y-20, equipped with four Russian engines, was on demonstration flight at the last Zhuhai Air Show.
Two Chinese engines under development may however correspond to the next Y-20 propulsion. The first is the WS-18 , a sinister version of D-30KP-2, which thus adopts a performance similar to 12 000 kgf of thrust. This engine that could eventually replace its Russian counterpart on the H-6K bomber, for example, was delivered in September 2014, but its latest status is not made public.
The second Chinese engine is the one targeted from the start by the Y-20 program, namely the WS-20 . It is a turbofan with a high bypass rate with a thrust estimated between 13 200 and 16 300 kgf, whose development would be based on the core-engine of WS-10 .
It should be noted that according to Chinese sources, the WS-20 has just been dismantled from the 760 flight test bench of China Flight Test Establishment (CFTE) after a long testing campaign started in November 2012. It should therefore continue Its flight tests on a new prototype of Y-20.
In terms of timing, the WS-20 appears to be more in line with entry into service around 2018 or 2019, as indicated by Chief Engineer TANG. It is also known that Xi'an Aero-Engine Corporation, which is responsible for mass production of the engine, has been studying since 2015 the installation with the help of the Polytechnic University Of the North-West.
The WS-18 made its first flight on a flying test bench of CFTE in September 2014.

One should however wait for the institutional elements, or spotter pictures, to know which of the two Chinese engines will equip the Y-20 first.

what the heck? I thought they would already be on WS-18. I guess it's still technically at the period between design certification and being really able to mass produce it. Either way, this is slower than I expected.
the plan all along was to start with WS-18 and then move on to WS-20.
You mean that you expected the WS-18 on the current Y-20s in service? I always thought it is DK-30 to this day.
If not (meaning DK-30 currently), then the "domestic engine" can be either WS-18 or WS-20. If Tang meant WS-20 then it is not slower than expected.

I don't see it that way. This is the first time that China built high bypass engine for large transport aircraft. So delay is to be expected. It is no less slower than the standard time development of this class of engine Take PW200-117 that power C17 Mind you it is bigger engine 140kN vs 165kN
It first flew in 1991 but still suffer uncontained turbine failure in 2008. 15 or 20 years development time is quite common
The powerplant first flew on the C-17 in 1991.
The PW2000 also powered the abortive ; the engine first flew on the Il-96M in 1993.
On October 16, 2008 the NTSB recommended that the FAA issue urgent new inspection procedures on the PW2037 model of the engine, following an uncontained turbine failure event in August 2008. The NTSB recommended that the FAA order PW2037 engines inspected beyond a threshold of flight hours or flight cycles less than that of the event engine, and be reinspected at regular intervals.
WS20 star flying in 2014 so it is only 2 or 3 years from first flight What do you expect miracle?
Every new engine suffer teething problem Check the engine failure for A400
I like what Chen Xiangbao has to say about this
"For instance, we are able to develop the two most important components in an advancedengine — the single crystal superalloy turbine blades and powder metallurgy superalloyturbine disks — but in mass production, the products' quality is not very satisfactory," he said. It is a matter of time and persistence to make reliable engines, he said.
"The road to success is filled with setbacks and failures. Each of the world's engine powershas walked this road," Chen added.
YinZeyong, head of AECC's science and technology commission, previously said that a good engine is the result of not only good design but also time-consuming experiments and tests.
