Not a big deal, the only problem for China is engine's high-temperature material need time to research ... AVIC will solve the last problem in future.

太行发动机真行了？站在太行涡扇10旁的老董很肯定地点头：行了！
is taihang ok?: yes, it is ready!

太行涡扇10发动机是中国航空研究院606所的产品，老董是606所的参展人员，这几天他天天站在展馆，给感兴趣的专业和非专业人士答疑解惑。老董说，他从南京航空航天大学一毕业就参与了涡扇10的研制。

涡扇10从1978年预研，1987年立项。老董说，它现在已经大批量地装上了歼10B、歼11B和运20大型运输机。

网上一些文章透露，太行发动机的外涵盒子，用上了复合材料，既大减了重量，又提高了强度，也提高了耐高温能力。老董先生带记者到太行发动机的侧面，指 着发动机外表那片黑色说：“这是我们所独有的特色，以前这里是用钢材，也有用钛合金，现在用复合材料就轻多了，还耐高温，高强度。”

老董说太行涡扇10发动机的推重比在8左右（发动机的推重比是指发动机的推力和发动机重量（重力）的比值），一般的三代机的发动机，都在8左右。他还透露，现在几个研究所正在联合研制的四代战斗机的发动机，在网上称为涡扇15，那款发动机具备隐身性能。

歼10B作为一个轻型战斗机能够载重近8吨的武器，机动性能非常优秀，这得益于它已经有了一颗强大的中国“心脏”。

对话太行涡扇10发动机科研人员

中美发动机 差距不到10年
china & usa engine gap is <10yrs.

记者：12000KGF-14000KGF有什么含义？

老董：这是说明太行发展了很多种机型，我们最好的发动机已经达到14000公斤的推力。（苏35的发动机推力为14500公斤）
taihang new derivatives comes close to 14000kgf ( su35's 14500kgf)

记者：达到这样的推力，就是说太行发动机与苏35的发动机推力大致相当了？

老董：是的，而且我们还在向前发展，这几年一直在完善和发展。这是最新的涡扇10发动机，已经定型了。

记者：它已经量产了吗？

老董：已经大批量装上歼10B、歼11B和运20。

记者：为什么歼10，比如八一飞行表演队的歼10用的还是俄罗斯的发动机呢？

老董：中国购买了那么多俄罗斯的发动机，还有已经装上的俄罗斯发动机还没到寿命，当然还要用呵。

记者：涡扇10在发动机寿命和稳定性方面与俄罗斯、美国三代机上的发动机比怎么样？

老董：这方面我们差一些，也可以说有较大的发展空间，比如说有些材料在科研单位的数据是不错的，但在实际应用时，还是不尽如人意，这就是研究航空发动机的难处，一个发动机要在相当长的时间内逐步完善它的稳定性，就算是美国也要十来年，而且还不算他们的预研阶段。

记者：网上有人质疑中国发动机不行，说太行发动机只有300小时的寿命，这是否属实？

老董：这个错大了，我们太行的寿命是1500小时，按照设计要求，300小时是定期维护。
life span is 1500hrs, 300hrs of scheduled maintenance

记者：我们的发动机与美国的差距有没有10年？

Summary

-new variant of WS-10A engine reaches 14000kg thrust and has certify
-WS-10A has started mass equip of domestic aircraft like J-11B, J-10B and Y-20 transport aircraft.
-WS-10A still not fully equipped all domestic aircraft is becos many AL-31 engine lifespan has not used up.
-lifespan of WS-10A is 1500hrs and schedule maintenance every 300hrs
-China aeronautic engine technology gap with US is less than 10 years.

China is engine's high-temperature material

Is it because China doesn't have the raw materials for this ? or is it some man made alloy that need more time to produce?

 

[帅的一匹]

Taihang engine really capable? Standing next to Taihang turbojet engine WS10 Mr. Dong said that WS10 engine is now fully operational and matured.

WS10 engine is Chinese Aviation Research Institute 606's product, Mr.Dong is exhibitor of China aviation research 606 institute, these days every day he stood in the hall, elaborate WS10 engine story to professional and non professional vistors. Mr.Dong said, he graduated from Nanjing University majoring in Aeronautics & Astronautics and started to participate in the development of WS10 engine since his graduation.

WS10 pre-study started from year 1978, project set up in year 1987. Mr.Dong said, WS10 had been massively mounted on the J-10 B andJ11B fighters.

Online some articles reveal, Taihang engine outer culvert box, using the composite, which greatly reduce the weight, also improves the strength and the ability of resistance to high temperature. Mr. Dong with a reporter standing besides Taihang engine, pointing to the black pitch appearance of the engine that said: ‘this is our unique characteristics,previously used here is steel or titanium alloy. Now with this newly developed composite material, which is much lighter/higher temperature resistance/higher strength’.

Mr.Dong said WS10 thrust to weight ratio at about 8(the ratio of thrust to weight refers to the Trust power per unitary weight). The fourth generation engines, are all around 8 TW ratio. He also revealed, several China aviation research insitutes now are jointly developing the 5th generation fighter turbojet engine with TW ratio 10. The Chinese military fans called it the WS15 峨眉 ,which fugures stealthy layout.

The J-10B as a lightweight fighter capable of carrying nearly 8 tons of weapons and excellent mobility performance, all credit to having a strong China 'heart' of WS10 series.

Following is the Dialogue details about WS10 indigenous engine with Mr.Dong:

Sino US engine gap less than 10 years

Reporter: 120kn-140kn what is the meaning?

Mr. Dong: Taihang developed many kinds of DERIVATIVES, the newest WS10 series engine has reached 140KN thrust. (Su 35 engine thrust of 145 KN)

Reporter: Achieve this thrust, that is to say the Taihang engine and Su 35's 117s engine thrust being roughly equivalent?

Mr. Dong: Yes, and we are still moving forward, the past few years has been to improve and develop. This is the new WS 10 engine, which have shaped up.

Reporter: It has started MASS production?

Mr. Dong: Mass service on the J-10B, J 11B.

Reporter: why the J-10, such as PLAAF eight one aerobatic team still with Russian engines?

Mr.Dong: China had bought so many Russian engine, We still utilize those engine until the life span expired.

Reporter: Can you please shed some light on the life sapn of WS10 compared with Russian and United States fouth generation engine?

Mr. Dong: We are slightly inferior in that part,while we have a larger room for progress. Such as some of the material shows good performance data in scientific research test, but in practical application, is still not satisfactory. It is the difficult part of aero engine development, It takes decades to improve its stability and even so with USA, not including the conceptual phase of the engine.

Reporter: Online question said that WS10 ENGINE has less than 300 hours life hours, whether this is true?

Mr.Dong: This is wrong, WS10's life is over 1500 hours, completely in accordance with the design requirements. 300 hours is the span between each regular maintenance.

Reporter: Our engine gap with the US is there for 10 years?

Mr.Dong: Less than 10 years.

Now everything is clearly put there, time to celebrate. Cheers to all Chinese members in PDF. @all

 

[Beast]

I think J-10B still not put into service is becos they are busy swapping the test AL-31F into domestic Taihang engine. J-10B will enter service with Taihang.

 

[ChineseTiger1986]

14000kg or 137kN = the mass produced Taihang engine, not the heavily modified one (limited version of the WS-10 series) for the J-20.

1500 hours = overhaul lifespan (the prototype has passed 1000 hours of ground test back in 2005)

300 hours = scheduled maintenance

Chinese J-11BH 'aggressive' with USN P-8A, says DoD - IHS Jane's 360

WS-10A fully operational and install on operational units.

The J-11B is a copy of Russia's fourth-generation Sukhoi Su-27SK fighter but with many modifications, including new radar and avionics, indigenous weapons, and a Chinese powerplant in the form of the Shenyang-Liming WS-10A turbofan engine. The J-11BH, which is the PLAN variant of the J-11B, started entering PLANAF units in early 2010 and may be equipping up to three units, including the 8th PLANAF Division at Jailaishi Airbase on Hainan Island.

The J-11BH unit that intercept P-8A is fitted with domestic WS-10A Taihang engine.

The black nozzled Taihang engine has used some special composite materials which makes them superior to the regular one with the silver nozzle.

I want to confirm that the engines on J10b mass production version are WS10 or not?

 

[aliaselin]

Some guys from CD forum has asked the deputy chief designer of Taihang themselves, and the editors is not very professional so made some mistake about the report:

不用扯了，什么小编啊，伦家董工说的是十四吨行型号的寿命达到了1500小时，，不达到十四顿的投产型号自己对比414最近型号两种模式，三百小时是维护时间不是大修，，太行引入了西方的视情维护概念，，，涡轮单晶盘四千多小时，，，什么小编听一般，在自己脑洞一开乱补，，，在现场的可以去再证，，，对了打的费和午餐饮料费发票谁给报销，，对了说好的平秃呢，，臭鸡蛋都唔熟了

Lifespan of 1500h is a new 14T version of WS-10A, while the old one has a lifespan of 4000h

The black nozzled engines are the AL-31FN, not the WS-10A.

Why the service life is shorter for the new version? Because of increase in thrust to 14 kn?
