Chinese Engine Development

Any source for that ??? ... As far as I know the WS-10A was built to nearly the same dimensions to fit both the Flanker's and the J-10's engine bay !

the Diameter of the TaiHang's intake is approximately 950mm for more airflow (total mass flow rate : ~120kg/s at SLS) ,and Its diffuser frame is slightly bigger than АЛ-31Ф's ,etc

The above article mainly talks about how WS-10A has helped China in other projects and such. In terms of developing gas turbines (QC-70 and QC-185) + developing turbofan engine for transports. I think they are basically just description WS-10A as a major success here.

This is kind of exciting, just talks about plaaf reps coming to shenyang liming overlooking the development of the improved Taihang engine. And that, this engine is currently on the testbed.

Just a little bit more translation on this article. It says that pilot really have strong faith and happiness toward Taihang engine, it's a good basis for development of all sorts of future military and civilian engines. While it states the need to be more reliable, it cannot sacrifice on the performance.

Also, there are some rumours of China co-producing AL-222-25F

I recall WS-10A was only declared certified in early 2007. Why is it all these other technologies (like gas turbine) based on the WS-10A development has appeared already.

My explanation is that all these technologies were actually overlapping to a great extent.

That's a reasonable explanation. Another factor is likely the very long certification process for aircraft engines.

You can have the design of the engine basically finished, but still have several years of certification work (and small changes to fix reliability problems) ahead. In the meantime, the engine might be perfectly useable as a gas turbine, that doesn't have the same strict certification or reliability requirements.

For the engine developer, selling the derivatives as soon as possible can help with recouping the R&D investment quickly. The additional investment required to create a gas turbine derivative is relatively small, and you can get some cash coming in relatively quickly, while your aircraft engine might still be a few years away from generating revenue.

Here is a nice timeline of AVIC engines:

How about uploading them to imageshack or any other file server and link them here ... ?

I believe this is the chart.

一航黎阳发运两批航空发动机

　　本报讯 中国一航贵州黎阳航空发动机公司完成了2008年第一批交付的发动机生产任务。2月9日农历正月初三，在浓浓的新春佳节气氛中，一航黎阳两批出厂的发动机装车发运部队，放响了新年第一炮。

春节前夕，贵州省遭遇了50年罕见的凝冻天气，由于贵州电网损坏严重，一航黎阳生产用电受到限制；恶劣天气造成连续10多天交通封闭，生产材料供应也频频告急。在这样艰难的情况下，一航黎阳在积极抢修保证生活供应同时，千方百计协调生产用电，确保推进生产任务。

在灾情刚刚好转之后，一航黎阳决定组织拼抢生产任务。除夕前几天，公司各厂都在紧锣密鼓地加紧生产。黎阳厂盘轴车间、装配车间和试车车间在生产部门周密部署下，利用春节假期，争分夺秒地抢干排故机任务。公司各厂从正月初三开始，每天都有700多人次在现场拼抢任务。

just talks about the first two deliveries for this year by Shenyang Liming, looks like one is for WS-10A and the other is for kunlun.

No, this article talked about LIYang in Guizhou. I think they build WP13 for the J8F and WP14? But I could be worng.

WP-14 is Kunlun. I believe earlier models of the J-8F used late versions of the WP-13 but switched to Kunlun WP-14 later.
