Chinese Engine Development

To admit, I'm a bit surprised by your quite bolt statement, especially when the text says that there are indeed issues, it might only appear eventually this year and this image is clearly wrong (since it does not show a WS-20, but a regular D-30KP-2), which in general makes its credibility highly questionable.
I think you just quote is out of context China always say they have difficulties just to emphasize that they fight and successfully overcome the difficulties. It is cultural thing though you are familiar with Chinese thing but you still does not comprehend the cultural nuances of Chinese speech.

The article said clearly they should be ready to batch produced the engine. It is common for Chinese article to use stock photo as substitute for real thing because the real thing is not available yet So the fact that it is DK30 photo does not depreciate the article in anyway.
Mind you he inferred that conclusion based on the phrase of official statement we will see if it true

Here it says at the beginning of the article
A lot of discussions have been made recently on the imitation of the Russian-made D-30KP2 turbofan-18 engine as a recent hot spot for domestic aviation. As the domestically produced large aircraft engine model, it has the lowest technical difficulty, the fastest progress, and the most widely used product. Everyone naturally looks forward to the entry of turbofan-18.

▲ "Oath of the Oathmaster" is after all a very means. This can be done for the first batch of production, and the improvement of daily management is even more critical.

According to the previous orders for several batches of D-30KP2 turbofan engines signed by China and Russia, 2020 will be the last year of Russian delivery in accordance with regulations. This year Russia will deliver 58 engines in the final round of China. If all of these engines are used in the production of Yun-20 and H-6 series, they can actually meet the production of large aircraft in West China in 2020. And considering that the turbofan-18 produced and delivered in 2019 should also be put into the production of Yun-20, so if all goes well, the output of Yun-20 this year will increase a lot compared with previous years; even in turbofans There are some problems with the cooperation of -18 and Yun-20. This year can also be used as a transition year for turbofan-18, so that the aviation and aircraft manufacturers have time to run in with each other.

From this perspective, whether China and Russia will sign a new purchase order for the D-30KP2 engine from 2020-2021 can be used as a side proof of the smoothness of the application of the turbofan-18 after the batch production is delivered. After all, China is not just relying on the D-30KP2 / Turbofan-18 engine for this large transport aircraft, the Chinese Air Force's strategic nuclear strike force, long-range precision strike force against the second island chain, and the backbone of air-launched anti-ship missiles. The main bomber used by the Force also has a large demand for turbofan-18A engines. Even in the Air Force's future bomber projects, the D-30KP2 / Turbofan-18 engine may still play a certain role.

From this perspective, the importance of the D-30KP2 / turbofan-18 engine to the Chinese Air Force is beyond doubt. Whether Chengfachang ’s “decisive battle” over many years has gone smoothly is not only an examination of its own destiny, but also a major event concerning the future direction of the Chinese strategic air force.

Can you summarize this article? The translation is very confusing to read. I hope there are some good news with the WS-18, because that would be a big step for any future strategic bombers and the Y-20.

Basically the article states the final 60 days push for 10 teams of designers/ engineers from AECC Aero Science and Technology Co Ltd for preparation of delivery of the first of a new aircraft engine with reverse thrust (note: the only aircraft equipped with reverse thrust in PLAAF are Y20 and IL-76).

Note that the article is dated 2019 November 4th. Thus this 60 days finalising phase should have ended around 2020 January 2nd.

"Life engineering" could mean a project of ultimate importance to the future of the company, as in Life (if success) or Death (if the project failed).

The scope of final preparation in Chinese are:
以发动机交付作为检验自身工作的唯一标准;二是设计中心、工程中心、质量部立即指派专人驻点装试厂,加快现场文件审签和技术质量问题处理进度,形成快速的信息反馈链;三是对于缺件项,主责和主制单位要高度重视,特别是反推等制约当前交付的瓶颈项目,厂内厂外要充分协调所有资源,加快推进;四是装试厂要将装配试车任务细化到日,公司主管领导,项目经理,主责和主制单位要第一时间处理和解决好当日问题,确保问题不过夜。

1) Delivery of engine
2) Fast information/document handling on verification/technical quality matters from design/engineering/quality dept
3) Solving bottleneck matters, especially on reverse thrust, resources from inside and outside of factory.
4) Assembly plant shall have full details on engine fitting and testing, coordination from all managers and units to solve on the same day any problems encountered.

Just a few important point of the article.

IMO, it is regarding a new engine with reverse thrust without giving engine designation, but almost certainly it is for Y20. And if all went well as at 2020 January 2nd, we shall see serial production coming on line soon after that date.

Ok, I see. This is conflicting information with what we received at the end of last year from the stock offering from Hebei Cisri Dekai Technology Co Ltd saying that the WS-18 development has stopped because of blocks in metallurgy?

So WS-18 is a copy of D-30KP2. But i was refering to WS-20. It now has been flight tested since 2014 i think, and it appears that it still hasnt met testing requirements. When will it enter service?

I think we shall keep open as to whether the new engine concerned is WS-18 or WS-20 as there is no mentioned of engine designation in the news article. Time will tell, we just have to wait for photo to appear later this year.

The key word from the article is "to prepare for delivery of the first unit of the new engine".

In mind of the ongoing discussion in the JF-17 thread I tried to look for some more info on the WS-19 and stumbled across this image, which shows a bit better - since not psed - some details of the nozzle feathers!

Haven't seen any existing Chinese engine with copper tone yellow and metal blue coloured petals with serrated ends.

WS-20 is not a product of 420 Factory.
