Isn't WS-10a supposed to have TVC? Will it be 3D TVC nozzle? I thought this engine was certified or at least close to it. Are you guys saying they that this is not going to be primary consideration for J-10 and WS-13 will be the next primary consideration? From what I understood, J-10 was going to use WS-10 due to better performance in relation to AL-31.

Supposedly AVEN nozzle project is trying to achieve that. A 2d nozzle was shown in an air exhibition in China.

The engine has been certified if i recall correctly and has eneterd limited production levels. Apparently as for now it will be used on J-11B. We can reasonably assume that it is being(or has already been) modified for use on J-10. Due to the low production levels it cannot fulfill the requirement of J-10 and J-11B at the same time as of now. Once full production level comes along and modification for fitting it on J-10 has been completed it will be used on J-10.

Ws-10 was supposed to match or surpass the thrust on earlier versions of AL-31 that were bought for J-10. BUt i guess the latest ones AL-31Fn(??) are probably better than WS-10 in thurst and performance.

WS-13 is for Fc-1/JF-17.

If it was, JF-17 would not be facing engine problems.

Your thinking of the WP-13, the wopen engine that is desinged for the j-7G. The WS-13 is something different

Are these.... WS-10, crobato?

crobato · 03-24-2006

No they're Kunlun (WP-14). Kunlun-II in fact. When the Kunlun was first finished, news of that was never released to the media. But when the Kunlun II was finally finished, the media finally reported it. They're meant for the J-8II or J-7.

How do you tell bro? are there any special things in WS-10 (and other engines) that could be used to tell one from the other??

crobato · 03-25-2006

Because I have seen these pics before.

vincelee · 03-25-2006

Tam, just what DO you do?

crobato · 03-25-2006

For any particular reason?

These kunlun engine pics were from Zhuhai 2004 btw. They're not new pics. The gearboxes on the bottom are identical to those used for the WP-13s, intended to work on the same planes (J-8II, J-7). If you wish, you can compare the pictures with the WP-13 and check the gearboxes in particular.

vincelee · 03-25-2006

oh I know that. I was just wondering if what you do on forums relates to what you do in real life, just like Kramer. Will, in his case, did.

crobato · 03-26-2006

No what I do in the forums is totally unrelated to my real life.

swimmerXC · 03-26-2006

OK guys, please cut the chit-chat; you can do that with PM or start a thread like what Golly and Sam did.

swimmerXC · 03-28-2006

Crobato do you think these are Chinese engines?

crobato · 03-29-2006

I am not sure about the last three. The first two look like gas turbines used for electrical power generation. There is such a turbine for that purpose based on the WS-10. The third picture could be WP-7, WP-13 or R-11 Turmansky but I'm not that sure.

This is talking about the development of the Thrust Vectoring control?

It says the factory has the first domestic large size add temperature, add pressure testbed for fighter engines, the first domestic tstbed for thrust vectoring controller (any idea what the 6 in 6分力 is talking about, guys?)

I'm guessing this is the run about before WS-10B can be certified. Now, the testing for TVC can get started.

中国一航沈阳发动机设计研究所有国内首台大型加温加压航空发动机整机试车台、国内首台航空发动机6分力矢量整机试车台。杨军就是这两座发动机试车台的台长、高级技师。

杨军自1979 年参加工作至今，一直奋战在航空发动机试车岗位上。他具有相当高水平的电气业务知识和安装技能，并掌握一定的钳工技术和焊工技能；了解和掌握发动机基本原理，并能够在发动机结构和气动性能试验中熟练应用。杨军在发动机试车工作中具备构思设计和安装调试试车设备的能力，能够精确操纵发动机各种特种试验设备，多次出色地完成了建试车台和新机试车任务。

在建设国内首台大型加温加压整机试车台过程中，杨军带领全组同志创造性地完成了进气加温等关键设备调试，创新、完善调试方法，完成了重点型号发动机燃油加温等整机试验任务，获得各级领导好评。在长期试验中，杨军总结经验改进了发动机调整工具，大大提高工作效率，降低了实验成本。他总结设备运行规律，为设备维护、使用提供技术依据，每年节约400工时。

2002 年6月，杨军和他的伙伴承担起6分力矢量试车台多个系统的安装调试工作。在国际上矢量推力试车台屈指可数， 6分力矢量试车台设备新、要求严、难度高、自动化程度高；接受任务后，杨军周密安排，带领全组同志集思广益，攻克了大大小小几十个技术难关，出色地完成了台架、电气、油封、燃油、操作、辅助测试等系统安装与调试，安装定位一次成功。

2005 年，两项重要的发动机长期试车任务都在杨军所在的试车台上进行，其中初始寿命长久试车难度大、历时长，发动机油门杆变动次数多。杨军带领试车组凭着过硬的技术，对试车各个环节了如指掌，定期检查，确保发动机试验万无一失。他们每天完成10多个小时试车时数，没有发生一次故障，发动机分解检查良好，初始寿命长试一次通过，创造了国内发动机研制史上的奇迹。

杨军在工作中坚持高标准、高质量，近几年来完成了1270小时整机试车任务，荣获一航动力所劳动模范等多项先进称号，入选国防科技工业系统“511人才工程”技能人才，荣立中国一航二等功，被一航动力所聘为五大“ 技能带头人”之一。
