Re: the real WZ 10

still too small, china should focus more on engine development than the helo itself. if the engine isgood, you can make anything fly

So, engine now more important than steppers ?

Chinese engine technology is relatively advanced, the most advanced in Asia and perhaps only the USA, Russia, the UK and France have more advanced engine technology. In 10 years time .... I'd bet would be no.3 :)

You forgot to read this.

China is working with France to produce the WZ-16 turboshaft engine (1500kw 1800+shp) that is scheduled to enter in to mass production in 2014 then the WZ-10 should be able to carry the same amount of weapons as the AH-64.

Overly optimistic, plus only comparing to the weak doesn't prove much. The French and British have developed engines for the Concorde 40 years ago. The Chinese till this day haven't achieved it. If China was as advanced as you said, it wouldn't be using such antiquated bomber as the H-6, neither would it be still trying to import transporters like the Il-76.

Jet engines are state of the art masterpieces, even the American and Russians spent decades and trillions of investments in order to get it right. It's not as easy as just blathering and self proclaim, neither was Rome built in just one day. Currently China's problem is not lack of money or talent, it's just the sedimentation of experience and historical know-how. China has a lot of the finest engineers and the backing of the richest government. The problem is that a lot of the times, the blueprints came out and the manufacturing test-runs cannot meet the expectation of the original design.

On 2 April 2009, the director of AVIC (Aviation Industry Corporation of China) Lin Zuoming (林左鸣), stated that there were problems with the quality control procedures on the WS-10A production line, meaning the Taihang turbofan was still of unsatisfactory quality. He said that solving these problems would be a key step.[7] In addition to poor build quality, the engines suffered from poor reliability, the Chinese engines have been lasting 30 hours at a time vs 400 for the Russian originals.[8] Despite AVIC's issues with quality control, mass production of the WS-10 series engines would contribute significantly in improving Chinese industrial capabilities.[9]
This is quoted from Wikipedia, which itself are direct quotes from several prestigious sources. If you guys are interested, go check out the WS-10 post on wiki.

This example reflects the root of the problem, again, a problem from lack of experience, instead of lack of money or academic know-how.

On the other hand, the British, to a great extent, is even stronger than the Russians in the jet engine business. Since the fall of the USSR, the big bureaus in Russia haven't really advanced much, other than simply keep on revising the old designs. All of the current hot selling Russian engines date back to the old USSR. But the British came out with a lot of great engines, both in military and civil sectors. A380 , F35, Typhoon and even the new British large aircraft carrier will use RR engines.

Plus, a helo engine is no easier than a full fledged fighter jet engine. In fact, even harder in some ways, since it's not as crucial as fighter jet turbofans, hence attracting less backing and funding.

Of course China had made big strides in the last decade, but it still has too much catch up to do. Just the quality itself will keep bothering Chinese engineers for at least another 10 years. These things are not easy to solve, both polar bear and uncle yankee struggled for decades before they fully resolved the problems. And this coupled with mass scale production. With China current production scale, it will be even harder with such small production batches.

The French are not dumb and neither are they selfless. I'm curious to see how much of the final product is actually China's. Right now China has a craze for wanting to claim everything to be 100% indigenous, which in most cases is not true. Most engines aboard the new warships, including the 054A & 052C, were imported. Even some of the missiles on the J-11/Su-27 series fighters still use imported Russian missiles.

All of you here probably heard similar saying, it is better to give a person a fishnet than to give him the fish. It would be great if China could learn from the French, in terms of management and quality control, improving their product perfection rate and service reliability, than to simply just buy the engine.

Right now China is standing at a very weird crossroad. As a country, China has a very solid industrial infrastructure, it can literally make everything and anything. But due to the chaos over the last century, especially the wasted first three decades caused by Mao, China is really late at a lot of modern innovations. Although China could make anything, it still require "insider trade secret" to make their products better, which it lacks due to inexperience. Hence, the cooperation with the French is a great learning opportunity for China.

The new regarding WS-10A news was 3 yrs old news. Plus, it was a production prOblem rather than design problem.
I believe they have solve the problem.

Now u see why J-11B/ BS / J-16/ J-15 are flying around with domestic engine..

We are even going at 180KN thrust engine while there is not even a single news of EU going for a 10 thrust to weight ration engine.
O
As for the IL-76 transport plane, we are going for domestic Y-20 using domestic engine. Digging up old news dOes not prove anything.

He said china could get to no. 3 in what, engine development, in ten years? If WS-15 is in mass production by then (which at this stage there is nothing for us to doubt that won't happen), then that claim could be true, in the military arena at least(?). Regardless, those statements do not exactly counter his claim, which itself was open ended and speculative.

Jet engines are state of the art masterpieces, even the American and Russians spent decades and trillions of investments in order to get it right. It's not as easy as just blathering and self proclaim, neither was Rome built in just one day.

The problem is that a lot of the times, the blueprints came out and the manufacturing test-runs cannot meet the expectation of the original design.

I agree that experience is of course good, but historical experience not so much, and that goes for every other aspect of industry, not just jet engines.

This example reflects the root of the problem, again, a problem from lack of experience, instead of lack of money or academic know-how.

I just want to point out that WS-10 has been in mass production since late 2009 and has been equipping all new production J-11B/BSs and possibly J-15s since then, meaning that they sorted out their quality control problems.

Personally I feel the major limitations of chinese industry (includign engines) isn't know how or money but rather management.

Of course China had made big strides in the last decade, but it still has too much catch up to do. Just the quality itself will keep bothering Chinese engineers for at least another 10 years.

This sentence is too open ended. Quality about what? quality about mass production? Well WS-10 is already in mass production, after initial hiccups. So I'm not sure what exactly you mean.

These things are not easy to solve, both polar bear and uncle yankee struggled for decades before they fully resolved the problems. And this coupled with mass scale production. With China current production scale, it will be even harder with such small production batches

Actually quality control is easier with small production batches. One of the reasons why there were delays for WS-10's mass production was that there were unforseen mass production quality control issues compared to small batch production, where quality control was easier.

The French are not dumb and neither are they selfless. I'm curious to see how much of the final product is actually China's. Right now China has a craze for wanting to claim everything to be 100% indigenous, which in most cases is not true. Most engines aboard the new warships, including the 054A & 052C, were imported. Even some of the missiles on the J-11/Su-27 series fighters still use imported Russian missiles.

The imported Su-27s, J-11As and Su-30MKK/MK2s all use imported russian missiles, of course, because the planes themselves are imported and the PLAAF don't feel a need to indigenize every imported product they buy from abroad.

All of you here probably heard similar saying, it is better to give a person a fishnet than to give him the fish. It would be great if China could learn from the French, in terms of management and quality control, improving their product perfection rate and service reliability, than to simply just buy the engine.

There are multiple projects which the chinese are working on with foreign countries so they themselves can learn and develop. EC-175, WZ-16 turboshaft, Mi-46 are examples of this. You're preaching to the choir about the merits of co development versus simply buying a product. If anything the PLA themselves have recognized this fact decades ago.

Right now China is standing at a very weird crossroad. As a country, China has a very solid industrial infrastructure, it can literally make everything and anything. But due to the chaos over the last century, especially the wasted first three decades caused by Mao, China is really late at a lot of modern innovations. Although China could make anything, it still require "insider trade secret" to make their products better, which it lacks due to inexperience. Hence, the cooperation with the French is a great learning opportunity for China.

You're preaching to the choir about the last part -- but at this point there are only a few areas (in the military domain) which they need foreign assistance on, namely some engine types, and helicopters (possibly large transport).

As for the generalization about innovation -- I'm sorry but are you attributing a supposed inability or lack of innovating ability at present to the first three decades of rule under Mao??
Your argument would only make sense if the vein is that rule during that time set the country back in general, which I would agree with. But you need to catch up on lost time compared to the rest of the pack before you can innovate and lead.

At this point china has caught up in many industries (including and outside of military), and is starting to innovate themselves (they are world leaders in green energy, telecommunications, shipbuilding).

Re: the real WZ 10

i dont know about anyone else, but i find China usually finds very basic solutions to usually very complicated problems

the lab where i did my PhD has 2 Chinese post-docs, and both of them usually used very basic concepts to solve pretty difficult issues, basic concepts which usually normaly are missed out, but that is just my experience and may not apply through a wider field

3 years is nothing in those sectors. It took US and USSR decades to master producing single crystal blades. The Chinese obtained Rolls Royce Speys about 4 decades ago, and just recently did they completely copied it successful.

I believe they have solve the problem.
You can't just make claims on personal assumptions. You have to have credible backings. The story on the Spey engines were mentioned in a CCTV documentary. The Indians had countless great ambitious, jet engines been one of them, and few of the proposals were actually similar to the claim you just made. They also claimed to make 180KN level jet engines. Have they made it yet?

I'm not saying that China is not going to be able to make it. But it does take a lot of time and hard work. It's unrespectful to say that China could do this and that in just next few years. If it's that easy, then what have they been doing for the past half century? Sleeping? There is no easy path in the road towards perfect jet engines. The Russians and Americans have tried their best to kill each other for the past half century and jet engine was one of those top weapon that could do it. It is common sense that when human try to kill each other, all their inner potential get released. Even under this pressure, it took them decades to master it. China just came out with an engine that is only comparable to what Americans came out with in the 70s, you think it's possible to instantly come out with something that is comparable to American level of the late 90's?

By no means am I trying to bash China, I am Chinese myself and I'm proud to be one. But I just don't like the current netizen culture of bloating facts and overly cocky on current achievements. When you go on Chinese site, the titles of the posts are the hilarious to read. They are mostly products of wet-dreams and lack of reality.

Chinese military is advancing and the rate is accelerating. It is inevitable that China will be a major military power. But the road towards that goal is still bumpy and many obstacles lay ahead. Sweat, tears and even blood will be shed along the way. If assumptions and self-claims could produce results, India would already be the greatest nation on earth.

Mass producing doesn't necessarily mean the problems are completely solved. A lot of times in the military sector, a lot of weapons have to be equipped even if it's not up to standard. The news about short life-span of single crystal blades was from 3 years ago, which is not that long ago. How can you assume that the problem is already solved?

Remember the thrust vectored Russian engines used in Indian Su-30 jets? Those engines only have EXPECTED (even on the manual) lifespan of 30 hours as well, which is a joke. Western counterparts usually last for at least more than 1,000 hours, some up to several thousand hours.

Of course even the sub-quality WS-10 could fly, but how long can the engines last?

As for small scale production, it is indeed easier to control the quality. But only large scale productions could quickly make engineers and technicians learn to improve quality.

Re: the real WZ 10

The simplest solution is ALWAYS the best solution, always!

I don't know what field Asif is in when he talked about his Chinese labmates, but in biology/medicine, labs in China usually have all the tools that we normally use in the States. As a matter of fact, it is the Chinese labs that have lots of money and all the high-tech equipment now. I work at a medical school in the US and we always have Chinese colleagues either coming to the lab or going back to China after visiting. they always say that Chinese universities are now loaded with money. And we also have Chinese recruiters coming to the school to recruit potential professors willing to go to China. They offer excellent start-up packages that are typically significantly higher than those offered by American universities. Note that I'm not talking about salary, but start-up funding, which is typically ~US$700-800K vs. US$550-650K we would get in the US. Of course, the problem with doing research in China is not about money, but politics, which discourages a lot of people from going.

And with the typical funding opportunity, here in the States, NIH is giving out less and less money. We have to work our butt off and still can't get enough funding. the funding % with NIH is now merely 7-8%. In China, however, people can get loads of money with only a couple pages of proposal. We have many professors in the department who collaborate with Chinese labs. So what I have said is fact.

So the comments about "no money no tools" no longer applies to China's scientific research.

Re: the real WZ 10

Vesicles what field are you in, I did my PhD in biophysical applications in molecular biology, basically using single molecule FRET to look at dynamics of molecules, the pioneer of this technique is Steve Chu from Stanford University who i met in 2007 at the ACS in Chicago

Hes also the energy secretary now and also won the Noble prize in Physics for his work in 1997, he's a Chinese American


My supervisor also last year got a grant from the Chinese Academy of sciences for work here in the UK, a very rare occurance

Hey, another fellow biochemist/biophysicist!

I did my PhD in membrane biophysics and biomechanics at Rice University. I was mainly using micropipette aspiration to measure the ability of biological amphiphiles to alter phospholipid membrane mechanical and electrostatic properties. My current focus is spatiotemporal organization of proteins, or lipid rafts, on the plasma membrane.

I was at the 2006 ACS in San Fransisco, but I normally go to the biophysical society and FASEB meetings.

My projects also involve FRET heavily. I am currently using FLIM-FRET to study the stability of protein nanoclusters in the plasma membrane. Unfortunately, no smFRET yet. My main technique is electron microscopy combined with spatial mapping to quantify the dynamics of protein nanoclusters.
