Crew safety features, defensive features, radar, avionics, engines.... etc etc etc.

Not wanting to quibble, but out of real curiosity from the above, which do you think the C-17 demonstrates an "advanced"-ness, of?


Its political reason. Contrary to popular belief, in my opinion, Russian never invited China to participated in the 5th generation fighter design.

Actually contrary belief is that Russia never invited China to participate in their 5th gen fighter design. But the fact remains that if the PLAAF couldn't get indigenous industries to provide a to-par 5th generation fighter then they would have joined the Russians, or even asked to join.
and if the PLAAF really needed to join, the Russians would've let them, considering how deep the Chinese pockets were, and is.

But the PLAAF didn't ask to join, and independently produced a 5th generation aircraft, so isn't this part of the discussion sort of moot?

Russian has much deep rooted fear about China due to misguided historical reason. So Russian instead cooperated with India. I think this really piss off China in some way, and you can see all the projects Russian help China on are not that strategically critical (I think that heavy lift helicopter project is the only thing left now?) - while the projects Russian cooperated with India all are at the forefront of the technologies with significant strategic importance - PAK FA, BrahMos, MTA (Multirole Transport Aircraft), GLONASS, T-90S, INS Vikramaditya, Akula-II, Tu-22M3...etc). Essentially, China is been left out, Russian is given China the cold shoulder and the Chinese leadership recognize this - you might retort and say the latest "cooperations" between Russia and China have been very close in past few years, but that's just posturing. There is little substance to these posturing. All those "friendship Pact" or "Bilateral Understanding" have very little substance in geostrategic term. China essentially has shifted from cooperating with Russia to cooperating with Ukraine because Russia is practically stopping all cooperation with China. All critical systems and designs are now coming from Ukraine - a country that is "at odd" (or sort of cold war) with Russia right now.

... Sure there is the political reason, and the fact that the Indian arms market is the biggest in the world and Russia would obviously want to get as much of it as it can which the US and Europe won't be able to take. Meanwhile China can already manufacture most of its own stuff.

Of all those systems you listed... Well China doesn't have a desperate need for it do they? The heavy helicopter project is an area which the PLA is very deficient in, therefore two and two make four. (And since when was India in deep with the Tu-22M3?)

You also make it sound like the fact the Chinese and Russian industries aren't very close means China is somehow losing out. The only thing the Chinese need from the Russians in terms of hardware and experience is helicopters and engines.


I like to believe J-20 will be as advance, or even MORE advance than F-22. But I think that would be just wishful thinking for now. Its one thing to "wish" for something unattainable, its another to make it attainable. Look at the abandon J-9 project - China wish for a super sonic interceptor in the same class as Mig-31, but China was just too far behind the technology curve at the time it simply didn't even know where to start to make it reality.

Well times change, right? And was the J-9 let go because they didn't have the tech? I always heard it was because SACs proposal was much safer and less drastic.

J-20 might look like its flying now, but we have absolutely NO IDEA of its capabilities and sophistication at this point. It could just be a flying airframe for all we know. The real war fighting capabilities is not something we can deduce from just looking you know. Sensor suites, radar, engines, BVR missiles etc etc these are the things that really matter too.

That's why I said, let's assume it is as advanced and capable as other 5th generation aircraft, because from everything we've heard do you think the PLAAF would settle for anything less?


That is a valid reason too - brand name and brand image.
But more than anything else, I think Chinese aviation industries is just lacking behind generally, but in term of developmental organizational structures, China is seriously lacking - and I think that's why China wants to partner with the west - to learn about the procedures, and organizational / system thinking like in the west.

Sure, I agree with that. But you have to be careful to lump all the AVIC companies and other smaller aviation companies in a big group. The management of CAC for example is obviously better than SAC.

China has to shift from "centrally planned" research funding paradigm to a privatized competition based paradigm. Most of the most critical researches are still coming out from government funded research labs and universities. While same can be said it is the same in the west and developed countries, but the percentage is not the same, as many western conglomerates are fully capable of funding its own research independently. It is organic vs planned. So when it comes to defence industries, Let's put it this way, American/EU can source from wide ranging technologies and products from the "eco-system" they created - from avionics, missiles, radars, software, stealth materials, robotic maintenance tech etc etc, while China has to rely on its government funded "research institutes". There are very few (there are beginning to have some now, but most of them are in relative low sophiscation) private defense conglomerates in China that Chinese military can source its technologies to solve its problem from. American on the other hand have so many privatized "help" the government can source from, the whole country is practically moving towards total privatization - from private military contractors (PMC - Blackwater/Xe) to private strategic think tanks.

They're already privatising their contractors, though they can a bit more. Shipyards compete for contracts, and I'm sure you've heard of the whole CAC canard delta vs SAC triplane thing for the J-XX. So there is competition, but the reason they're going to foreign companies is brand name and to boost smaller more upstart companies with more experience.


Again, this is what I am getting at....with so many aircraft companies - for some reason China just cannot get upto the same level of sophistication and resources as western companies.

Well duh, most of these companies don't exactly have much experience do they, nor access to money and there simply wasn't the requirement for many aircraft, of whatever shape and size, before.

"For some reason" -- has it occured to you how the PRC's economic situation from the cold war to now has effected the chinese industries in all walks of life?

You can't really say "with so many aircraft companies - for some reason China just cannot get upto the same level of sophistication and resources as western companies" when they've barely been given any time or as much money or contracts or the sheer need for the same number of projects western companies faced in the cold war.

Come back in twenty or thirty years. At that point you might be able to make that claim... if the chinese aerospace industry isn't at the same level of "sophistication" as western equivalents that is.

All of CAC, SAC, XAC..etc etc combine will divert the focus from more critical defense project (even you agree) - means AVIC / Chinese aviation industries as whole lacks design talents, manpower, and breadths of research.

Compared to who, and why do chinese aerospace companies lack "talent, manpower and breadth of research"? I'm espicially critical about the last claim. How do you define "breadth" and "talent"?

I was saying that it'd be stupid to get the big players in AVIC to do something mundane such as make a wholly indigenous 737 class aircraft when they could be doing something else (I'm not sure about what resources they would drain, but the fact even if it reduced productivity of defense by 0.000001% that would still be a stupid thing to make CAC, SAC or XAC do). The smaller companies could work together to build such a plane instead.

This is a inherent organizational problem at systemic level. Compare to the west, where Boeing / Airbus / Lockheed can take on multiple highly sophisticated, high risk projects on its own, and source from wide ranging affiliated partners and subsidiaries.... China simply just can't do that. Yet.


Previously I got the notion that you thought the Chinese aerospace industry wasn't great because they couldn't "even" manufacture a commercial airliner, but now you're saying they can't because they have too many independent compaies which can't manufacture a commercial airliner...

And really, where did you get the idea that all the independent companies like CAC, SAC and XAC cn'at source from "wide ranging affiliated partners and subsidiaries"? Do you think they make all the radars and avionics themselves or something..

And CAC's taken on quite a few highly sophisticated high risk projects on its own, J-10, J-20, JF-17, and other associated UAV and UCAV projects, which is a pretty good record.

Let me give you an example. The ballistic missile / rocket program for example, are sourced from hundreds of companies, even every "stage" of the rocket is made by a different company drawing from its own specialization and research/patents - eg. Boeing maybe for 3rd stage, Martin Marietta for 2nd stage, TRW for 1st etc..etc.. I think ALL the chinese rockets are manufactured by CALT.

The stealth fighter projects is the same - its a high risk, highly sophiscated project. The original F-22 wasn't just made by Lockheed. Lockheed LED the project. There were hundreds of companies under guidance of Lockheed and provided products, technologies, solutions to the project that led to the eventual success of Lockheed winning the project. Oh yeh, and Lockheed wasn't the ONLY ONE in the competition too.... Lockheed Martin was in competition with Boeing, General Dynamics, Lockheed, Northrop, and McDonnell Douglas. American aviation industries has so many talents they can actually create multiple teams to compete with each other! That's what it means to have a huge talent pool. I heard a lot forum posters deriding me for saying "China don't need to have competitive bidding system like American". I think that's just short sighted to think that way.

Do you think CAC is building everything for the J-20? Of course they have subcontractors as much as Lockheed did. And SAC competed for the contract too. There obviously wasn't as many bidders for the ATF project though.
You seem under the impression that having sh*tloads of companies independently = success.

I know it sounds stupid when I imply that, but CAC is part of AVIC. It shares the same resources with all the other companies in this group. Do you think Lockheed, Raytheon, Boeing share their own technologies/patents with each other? They don't even share their own private laboratories!

That's the thing. Do you think CAC shares all the same resources with all other companies?

Let me give you another example. The J-20's WS-15 engine - is going to be sourced from SAC. SAC! The same company CAC is in supposedly in direct competition with! Since engine is critical component that's linked to so many other sub-systems and design of the aircrafts (power output to the radar/avionics/FBW/sensors/FADEC, aerodynamics), both SAC and CAC practically have to work together intimately to be able to make WS-15 fit in J-20. So is it far fetch to say they are all just part of each other?

First, WS-15 is from XAC.
Second, yes it is far fetched because companies in the US join up for projects all the time. SAC's a subcontractor for the J-20. Boeing's a subcontractor for the F-22. Same deal. XAC's a contractor for the WS-15 engine. Pratt and Witney is the contractor for the F-22's F119.

And this: "Let me give you another example. The J-20's WS-15 engine - is going to be sourced from SAC. SAC! The same company CAC is in supposedly in direct competition with!"

Well OMG lockheed and boeing were working on the F-22 together. But they were in competition over the JSF (X-35 and X-32)!!!! -gasp-

Companies work together all the time.

Isn't co operation between the companies a good thing? Yes it is.
Does it mean they're part of each other? Hell no, they're just working together on a project. It's like saying Lockheed and Boeing are "part of each other" because they're contractors to the same plane.

-------

I think you're trying to say that the Chinese aerospace industry isn't as mature or large as the US industry, which no one is arguing about.
But I don't exactly understand your reasoning -- one moment you're talking about contractors and subcontractors for big projects, and the next there's something about companies taking on multiple projects at the same time... Can you clarify your position (and use less bold and underlined words?)

Captain
JSF :

Proposal A - Boeing
Proposal B - Lockheed-Martin
Proposal C - McDonnell Douglas/Northrop Grumman/British Aerospace

* Proposal C was considered innovative but way to risky and eliminated

Proposal A - Boeing/McDonnell Douglas
Proposal B - Lockheed-Martin/Northrop Grumman/British Aerospace

So yeah competitors might work together on rare occasions -

and one of the rumours about the SAC being a subcontractor for the J-20 is that it was politics and nothing to do with technology... :eek:

Again, good point, but I still think EADS is privately funded - it has its own research centers and laboratories. AVIC and its umbrella groups relies largely on government funded research institutes.
And that doesn't matter. You're confusing advantages from being of the private sector with size advantages. PMCs might as well be of the state, since that's where all its money comes from. Is it private money? Yes. But it's private money given to them by governments. There is nothing unique between a private and public institution of research. What an organization is capable of is primarily size dependent.

What I mean is CAC has to work directly with SAC for its J-20 project even though they are direct competitor for the project. It DEFEATS the purpose of having the competition in the first place. In American ATF program for example, both Lockheed (YF-22) and Northrop (YF-23) sourced from 3rd party engine manufacturers General Electric and Pratt & Whitney. GE and P&W are neutral parties to them, so there is no gray area.

So, of course it is good to collaborate when the project is highly complex - drawing the best from each companies specialization, but not when you set out a competition for companies to compete in. It just seem silly if they are forced to work with each other even though they are in direct competition with each other.

Um...Northrop Grumman collaborated with LM after they lost the ATF contest. One subcontracted to the other (as well as other defence firms). The same happened with the F-35 between LM and Boeing. They competed against each other before working with each other? And the same thing is happening between SAC and CAC with the J-20 (not to mention all of the other companies in AVIC). They aren't being forced to work with each other any more than the American firms are. It makes economic sense when one company may have resources and abilities the other doesn't have, and there is only one project which they can use it on.

The main disadvantage of the Chinese aerospace is that the defense budget of China is very much smaller than that of the US. The civilian airlines of Boeing derived from their experience with B-47, B-52 and KC-135. 747 derived from a USAF competition for a very large transport aircraft. Lockheed lost and built scores of C-5's, Boeing won and is still building Jumbo's.

China is now developing a complex infrastructure of large and small companies within China but also with companies in America and Europe, including pure AVIC companies, but also an Airbus plant.

So, according to you, with HMS cued high off broadside missiles technology it has become absolutely no point in making aircraft agile? How about just making J-20 fly like a F-117? eg. a dump truck? :D
He never said agility is not important. You shouldn't put words into people's mouth.

I don't believe TVC will result in excessive energy loss. Show me a paper that says so. If energy loss is as you said it would be, why are F-22, F-35, PAK FA are all incorporating TVC into their design??
Show me a paper that says otherwise. Experience with TVC is that they create drag leading to energy lost.
[video=youtube;WKEa-R37PeU]http://www.youtube.com/watch?v=WKEa-R37PeU&feature=player_embedded[/video]
...All this is formidable on paper but what you would know is that with the TVC kicking in, its a huge aircraft, and thrusting such a huge aircraft in that direction creates a lot of drag. It's a big airplane. A huge airplane. So what happens is when it moves its nose around, its sinking. We had enough experience with the F-22. which has up/down TVC nozzles.



Like I mentioned in last paragraph, looking at the civilian aviation development tells you plenty about the military development... This is fact. It shows lack of maturity and sophiscation in developing avionics to the western standard.
KJ-2000, KJ-200, J-20, J-11, J-10, JH-7A, JF-17, WZ-10, and WZ-19... they all use Chinese avionics. The fact is, if Chinese avionics aren't on par with Western standard, Pakistan wouldn't have used them on their JF-17.

And you can't compare civilian aviation with military aviation in China's case. Just because civilian and military aviation sectors are equally large in the US and Europe, that doesn't mean it's the same thing else where. And when we discuss China, there is almost no civilian aviation industry to speak of.

This is parallel in the military sector - If I am not wrong, even J-10 does not have FADEC (Full Authority Digital Engine Control) - it shows the lack of sophistication of Chinese aviation industries. FADEC has been around for the past 30 years since 1970s - starting with F-111 (3rd generation aircraft) and majority of the 4th generation (F14, F-15, F-16,F18) etc.. The technology eventually trickle down to civilian side and hugely benefit the civilian market. Boeing started using FADEC back in 1984 on Boeing 757.
You need to have your own engines before you can develop a FADEC. FADEC is essentially a feedback control system, and to design a feedback control system you need to have knowledge on the system's performance parameters. These parameters come from engineering simulation models, ground tests, and test flights, and the only way you have access to them is by developing that engine from the ground up. You can't develop a FADEC for someone else's engine. So, a lack of FADEC on the J-10 is not a proof of lack of sophistication in Chinese avionics.

So the military aviation industries is NOT completely separated from the civilian side. It benefits each other when technologies developed from one side can always cross over to other side.
It is true that they are not separated, but that isn't the issue. The first problem lies in your use of China's civilian aviation development to reflect their military aviation competence. As I have pointed out before, you can't draw conclusion this way because there isn't a civilian aviation industry to speak of when it comes to China. The second problem is that you only see civilian sector benefiting military sector, whereas the reality is that they both benefit each other, and in China case the civilian sector has a lot more to benefit from the military sector.

Currently, looking at the sophistication of chinese civilian aviation industry development can tell you a lot about the sophistication of the military aviation industry development. The two are the same (or at least not that far apart). This is especially true in China's case because most of the research and fundings are directed by state (centrally planned). There are very few companies in China that is capable of R&D independently in high sophistication comparable to the state funding level (or its western counterparts).
This is in contrast to the western (defense) conglomerates where they can independently fund, research, and develop the technologies require for their products.
You are using the word "same" as one big weasel word.

When civilian and military industry receive their money from the government, it just means their source of funding is the same, which is not a proof that they are indeed the same.

That's just a stupid strawman argument you invented yourself. The only thing that has achieved is make your credibility nosedive.

Where did I say there is "absolutely no point in making aircraft agile"? :rolleyes:

My point throughout is that TVC only gives marginally better agility before the maneuverer becomes counter productive. What do you think will happen to your energy state and airspeed if you engage TVC to do a crazy instantaneous turn? And what is the point of doing that when you can just turn your head instead to cue a missile?

I don't believe TVC will result in excessive energy loss. Show me a paper that says so. If energy loss is as you said it would be, why are F-22, F-35, PAK FA are all incorporating TVC into their design??

How many times do people have to explain the exact same things to you before you start to comprehend what people are saying? I only ask because multiple members including myself have already address all of those points previously, backed up by real life experience from Red Flag. I see no point in wasting my time repeating things already said before. Go back and read some earlier posts and you will see all of your points have already been addressed.

CAC IS PART OF AVIC incase you didn't know.

I see my point has been completely lost on you. :rolleyes:

AVIC is just an umbrella organization, but all the companies it composes of are run and operate in almost exactly the same way as totally independently companies. Every major aircraft maker in China is part of AVIC and many compete fiercely with each other and all are at different levels in terms of capabilities, technology and speciality.


The point I am making about AVIC is that all the chinese aviation companies are grouped under this, all the research institutes and laboratories, factories, etc are on about the same technology level/generation. (Notice the emphasis on the underline part)

Both CAC and SAC are part of AVIC since you do not seem to realize. Are they both are the same tech level? It is quite obvious that most of your assumptions and conclusions are born out of ignorance of facts.

Personal attacks are not a convincing arguments, it adds nothing to your retort.
Explain to me why "civilian market and has absolutely zilch to do with military aircraft".
Give me plausible examples.

Its not personal attacks. Its simply a statement of observations since you clearly have gaping holes in your knowledge and understanding of how the companies in question works, and consequently, you conclusions are totally unsound.

The fact that you cannot seem to comprehend the difference between civilian grade equipment and military grade equipment is a perfect example of this knowledge deficit.

Please give me a single example where civilian standard gear has been put into military service without at the very least major modifications.

In addition, I have stated quite clearly that all dual use civilian equipment China buys is subject to strict evaluation by the likes of the US states department, and anything deemed to be too advanced/sensitive will not be allowed to be exported to China. Which completely shoots down your baseless theory that AVIC is buying civilian plane makers in the west to help the J20.

If you had even the most basic business knowledge, you would realize that it is infinitely more likely to be aimed at breaking into western civilian markets, and/or to meet growing domestic Chinese demand.

Like I mentioned in last paragraph, looking at the civilian aviation development tells you plenty about the military development. AVIC currently seems to be able to indigenously design airframes, while the rest needs to be imported.For example ARJ-21 programme is supported by 19 major European and US aerospace components suppliers, including General Electric (engine production),Honeywell (fly-by-wire system) and Rockwell Collins (avionics production).
Please, Log in or Register to view URLs content!

Yet more evidence of a lack of basic business knowledge.

The first rule of business is that the customer is king. The ARJ21 is designed to sell internationally, to make a profit. Why waste time and money re-inventing the wheel when you can buy things off-the-shelf? Boeing and Airbus does exactly the same thing in case you did not realize.

This is fact. It shows lack of maturity and sophiscation in developing avionics to the western standard.

That is opinion, not fact.

This is parallel in the military sector - If I am not wrong, even J-10 does not have FADEC (Full Authority Digital Engine Control) - it shows the lack of sophistication of Chinese aviation industries. FADEC has been around for the past 30 years since 1970s - starting with F-111 (3rd generation aircraft) and majority of the 4th generation (F14, F-15, F-16,F18) etc.. The technology eventually trickle down to civilian side and hugely benefit the civilian market. Boeing started using FADEC back in 1984 on Boeing 757.

You know what this shows? That you have no idea what you are talking about.

FADEC has nothing to do with the J10, its an engine feature for crying out loud. :rolleyes:

And the WS10A has FADEC since you obviously did no know. Even your cherry picked example is wrong.

So the military aviation industries is NOT completely separated from the civilian side. It benefits each other when technologies developed from one side can always cross over to other side. Currently, looking at the sophistication of chinese civilian aviation industry development can tell you a lot about the sophistication of the military aviation industry development. The two are the same (or at least not that far apart). This is especially true in China's case because most of the research and fundings are directed by state (centrally planned). There are very few companies in China that is capable of R&D independently in high sophistication comparable to the state funding level (or its western counterparts).
This is in contrast to the western (defense) conglomerates where they can independently fund, research, and develop the technologies require for their products.

This is a hopelessly wrong statement.

Since when has China actually put much investment in civilian aviation? The ARJ21 and C919 are the first real attempts since the Y10 was canned. China has focused its efforts and resources almost exclusively on military aircraft until very recently. You attempts to use China's weak civilian aviation sector as a yardstick for China's military aviation capabilities is plainly absurd and fundamentally wrong.

This is either caused by a shockingly poor knowledge base of the history and actual workings of the Chinese aviation industry, or is evidence of something trying to cherry pick evidence to support a position they already have entrenched before they knew anything about the Chinese aviation industry.

Crew safety features, defensive features, radar, avionics, engines.... etc etc etc.
Precisely what are crew safety features and defensive features? And what special radars and avionics does C-17 have that commercial airliners don't? And what make C-17 engines so unique? If you can't give precise explanation, then you have basically not answer Bltizo's question.

Let me give you another example. The J-20's WS-15 engine - is going to be sourced from SAC.
No it's not.

Again, good point, but I still think EADS is privately funded - it has its own research centers and laboratories. AVIC and its umbrella groups relies largely on government funded research institutes.
You "think", which is the big keyword here.

No, EADS is not privately funded. There was this huge fight between the US and EU on the WTO a few years ago, because Boeing (and other US aviation companies) receive government subsides while Airbus (which is a part of EADS) gets government loans. Government subsides and government loans are not private funds.

Asymptote,we do not intend to change your negative perception about china. But if you give miss informed info and sprout rubbish. I think the members are obligate to correct you. Go read more reliable info before you mix up SAC and XAC again.

Stop using text message abbreviations!!!!!
