Asked Obama, he said that it would be a disaster for the world if China became a developed nation.
Anyway, it doesn't matter if China has a good relationship with the West or not. China needs to develop its engine industry as it is the crown jewel of high tech. Saying that China doesn't need to develop its engine industry is like saying China should be poor and low tech forever.

Guys this is the Chinese engine development thread ... can we please take this discussion elsewhere?
Greetings all.
I have a quick question, though I'm sure it has been asked before.
Why chinese engines, like the WS-10, do seem to have a more fixed external exhaust nozzle for the afterburner compared to those in american engines and some russian engines?.

General
Some Chinese research into both 3D and 2D thrust vectoring.
The first paper is out of Chengdu and looks at 3D vector thrust:
Abstract: Thrust vectoring can significantly expand the operational envelope of fighter aircraft and improve their flight safety and combat capabilities. A key technology in aerospace study and one of the typical features of advanced fighter aircraft, thrust vectoring involves multiple fields such as aerodynamics, air intake/exhaust, engines, and flight control. The integrated implementation of thrust vectoring is an interdisciplinary, closely-coupled and high-risk systematic project. This paper reviews the development of fighter aircraft thrust vectoring with an analysis of its key technologies. Based on the engineering practice of the first axial-symmetric thrust vectoring demonstrator in China, this paper elaborates the research on high angle of attack aerodynamic design for internal and external airflow, thrust vectoring engines, integrated flight and propulsion control and post-stall maneuvering flight test verification of fighter aircraft and other related key technologies. Finally, the contribution of thrust vectoring technology to the combat effectiveness of fighter aircraft is summarized and its future applications predicted.
The second paper is out of 606 Institute and concludes that 2D is the way to go for 4th-gen fighters due to its simpler structure, superior stealth and IR suppression, lower drag, etc. Unfortunately, I only have some screenshots of the paper:

I dont understand chinese, but this video was posted on youtube on 23-07-2020 (seems that CCTV has a channel in youtube, despite the fact that AFAIK youtube is blocked in china). After all these years, is WS-10 still having problems like that?
Dude the 606 indivdiual was clearly referring to when the WS-10 was first beginning production ... do you not understand that a documentary can be (and usually is) referring to events which occurred in the past

Again, i dont understand chinese. So i thought that the information was recent.
Someone on Weibo asked Pupu if the WS-15 has a thrust of 18 tonnes, as stated by Song Xinzhi. He says he would believe the 18 tonne figure if it was the long term goal of the WS-15 (mentioning the 117S and the WS-10C as evolutions of the AL-31F and WS-10 engines respectively to compare with). Pupu also mentions that the WS-15 thrust should be a little over 16 tonnes at the current stage. It would be interesting to see if this pans out to be true. Nonetheless, at least we finally have a little more information on the WS-15.
Pupu also says 裤衩还是稍微红了那么一点点 (the pants are still a little red), in response to another poster saying he would feel ok if the thrust is 16.5 tonnes. Does this mean Pupu is saying the WS-15 thrust is slightly under 16.5 tonnes?
