Zhuhai Air Show 2014 - Updates & Discussions

if new taihang had 14000kgf the probabilty to buy su35 is very slim....

i dont think the engine gap with usa is less than 10yrs....should be more than that!

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.

AL31据说首翻在600小时左右,总寿命1500小时;而美国同级别的F100-PW系列和F110-GE系列首翻都在1000小时以上,总寿命更是接近4000小时。后来的F119和最近的F135、F136更不用说了

First overhaul of AL-31 = 600 hrs; total service life = 1500 hrs
US's F100-PW and F110-GE first overhaul = 1000 hrs, life = 4000 hours 8-)

There is still a huge gap between our engines and those of USA :undecided:

An unidentified Middle Eastern country is in “advanced” talks to make the first foreign purchase of a fighter jet jointly developed by Pakistan and China.

The joint sales team from the Pakistan Air Force and China National Aero-Technology Import and Export Corporationalso known as CATIC, are in advanced talks with 10 other countries to sell the JF-17 Thunder, said PAF Air Commodore Khalid Mahmood, who heads sales and marketing for the fighter jet.

“We are in advanced negotiations with a Middle Eastern country, but the political situation over there has delayed the deal,” said Mahmood in an interview at the Zhuhai Air Show yesterday, declining to give more details. “But we still expect them to be our first foreign client.”

The JF-17 Thunder fighter jet is among several aircraft China is seeking to export, after designating its domestic aerospace sector as a key national strategic industry. The twin-engine jet was jointly designed and manufactured by the Pakistan Aeronautical Complex and Chengdu Aircraft Corporation, a subsidiary of state-ownedAviation Industry Corp of China, also known as AVIC.

The partners are in “advanced talks” with clients in Africa, Asia, theMiddle East and South America for jet sales, Mahmood said. He declined to identify any of them. Prospective orders will be for the third block of 50 planes, with the Pakistan Air Force having ordered the first two blocks of 50.

Dual-Seat Version
Mahmood said there are plans in place for a dual-seater version of the JF-17 Thunder after feedback from potential clients. The third-generation fighter jet, also known as FC-1 Dragon by the Chinese, can be used for aerial reconnaissance and has air-to-air and air-to-surface combat capabilities, according to its product website.

Flightglobal, an aviation-related website, previously reported that the partnership was close to making its first foreign sale.

A mock up of the single-seat, single-engine JF-17 is on display at the Zhuhai Air Show that started Nov. 11 in the province of Guangdong, along with several others produced by AVIC -- including the J-31, one of China’s fifth-generation stealth fighters.

The J-31 gave its first public demonstration at China’s largest air show on Tuesday. Manufactured by a Shenyang AVIC subsidiary, the fighter is a test of the country’s ability to deliver cutting-edge defense technology.

Still largely-shrouded in secrecy, the production of the fighter could add heft to China’s sea and air expansion in the region and its push-back against decades of U.S. economic and military dominance.

Maybe next generation of engine spec like WS-15 will be better? Like 3000hrs lifespan and long interval of maintenance time?

Which is why the AVIC president put a 10years time gap between China and US.

We have come a long way though to have come this far! :-) :tup:
USA is also doing their own R n D in engines technologies too
So the gap is fairly large and I dont know if they said "less than 10 years" is way too optimistic;)

专家:中美发动机差距不到10年 太行大量装3款军机-空军版-超级大本营军事论坛-最具影响力军事论坛 -
2014-11-14 来源:羊城晚报 作者: 责任编辑:高辰




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。
twr ~8. ws15 in development phase has "stealthy features"

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?

老董:不到10年。(林丹)

10 year gap on engine tech is too optimistic. US has had F-22 for more than 20 years, and we are still working on a prototype of WS-15. We are at least 25+ years behind the US on aeroengines...

kindly tell me is their any thing from Pakistan showing interest in FC-31 or any other plans.............................:(

These Chinese people will be so proud of their country achievement .i envy them :agree:

Because we are looking for an excuse to help Russia's military industry complex by buying some Su-35, but in the reality, we don't need Su-35 from a technological perspective.

If that is true, can china lease or resell those Su-35s to Pakistan?

Su-35 & FC-31 :cheers:
