Re: China's transport plane capacities

well back then China was in a complete mess they had little money, no nowhow, civil war, foreign nations invading, little educated population, country wasnt developing, starvation, civil unrest, corruption.

so after all this to manage it in 20 years is still quite remarkable given the conditions their were in back then. but now their have ticked most of the list off and now have proper machinery not just handheld tools backthen. So it would be achieved lot faster. 20+ years to develop transport aircraft their fighters only took less then 15 years. and domestic J-11 took 7 years. y-9 pictures should be emergin soon hopefully.

IIRC the J-11B program started in 2002 and ended in 2007. This is 6 years at most. An indigenized Il-76 could be about the same.

Re: China's transport plane capacities

J-11B program took only 6 years because the China had Russian's full support in setting up the Su-27 production facility. SAC assembled Su-27 from around 1996, that's almost 8 years prior to the start of J-11B program. Plus, SAC had full access to Russian parts when producing them, and only recently increased the domestic content to above 90%.

If China purchased IL-76 blueprints and attempt to set up an unauthorized production line, you can forget about any Russian technical support or access to ready made parts. Just figuring out what kind of jigs, struts and other assembly tools are needed and how to arrange them would take a few years. I haven't even mentioned the most glaring problem yet: Where are you going to get the engines? Without Russian supply, China will be forced to make their own. Now do you copy the Russian engine or build a new one from the Taihang core? Copying the engine would take five years at least judging by the 20 years it took to copy CFM-56 core to produce Taihang. Designing a new engine from Taihang core would take just as long if not longer. Then you would have to retrial the engine on IL-76, which would take another year. That alone would mean no copy of IL-76 would roll off that assembly line for 5-7 years at the very least. Realistically, the assembly line won't even be set up until the engine program is at least approaching success. That means, no specialized production machineries will be even ordered until nearly 5 years from start of program. So that will be 5-7 years to get the engine, and another 1-2 years to set up assembly line, figure out the assembly process, train the people, and trial production can start, and real production starts after 1-2 years of testing. 10 years is the minimum time it takes to get production going if everything gets off without a hitch, like delays in the engine program, some specialized parts that can't be produced, etc. etc. Anyone who thought it could be quicker than that is just having wet dreams.

Re: China's transport plane capacities

If the PRC can get production rights from Russia, all the better, but having the blueprints is worthwhile nonetheless for better understanding of system development and equipment maintenance.

2002 to 2007, 5 years dude. Your math doesn't work here, 1996 + 8 = 2004.

Just figuring out what kind of jigs, struts and other assembly tools are needed and how to arrange them would take a few years.
that's the point, they are going to get more than just blueprints, but all the final assembly stuff. They already have all the major tools needed to do fixes on IL-76, this way know. And the machinery used in Chinese aerospace giants are far newer than the Russian ones. This is not 1996 anymore, the Chinese firms are no longer stuck using old soviet era assembly tools.

lol, your assumptions are ridiculous, why do you think they won't get D-30s from the Russians? They got plenty for H-6K program. As for this assertion that future engines would take 20 years, do you realize the concept that their technology and development skills are better now. Did you notice that they only started WS-13 in 2003 and it is suppose to get design certification this year. And the engine designed for transport is apparently undergoing flight test right now too. I can mention a bunch of other engines, but that's the gist of it.

your numbers are all over the place, seems like you are just mumbling here. You've shown that you don't know much about the speed of recent Chinese engine developments. You've shown that you don't know how advanced their factories and tooling are. You've shown that you don't know how much China already has IL-76 figured out. But hey, obviously according to you, it's easy to convert IL-76 to KJ-2000 without any Russian help. China has been studying this transport since the 90s. What they got here is a final kick in back.

At least I'm trying to justify my conclusion using some numbers. You just grab 1 year out of thin air. WS-13 program is basically a copy of RD-93, and even WITH RUSSIAN SUPPORT, it took 5 years to reach certification stage. Thanks for proving my point that it would take at very least 5 years to copy the D-30.

As for China still able to get D-30 even if they attempt to set up an unauthorized assembly line for IL-76, that what people call "Wishful thinking". The Russians are more likely to cut off supply of D-30 to the H-6K program as well if anything.

The conversion of IL-76 to KJ-2000 was most definitely completed with Russian help. The basic conversion plan was designed by Russians during the Israelis Falcon conversion program. KJ-2000 only needed to substitute Israelis electronics with Chinese version. So KJ-2000 has very little bearing on showing the depth of Chinese understanding of IL-76 structure.

Getting blueprints and assembly instruction is only a small part of the whole business of producing an aircraft, just as drawing up that blueprint is only a small part of designing that aircraft in the first place. The assembly plant at Uzbekistan can't help you design the manufacturing process at parts factory. They certainly can't help with designing the process to produce materials used if you can't make them already. Then even if you managed to figure them out, setting up production and getting all the parts to the assembly plant can't happen overnight either. It's a long logistic tail that can only gradually get up to speed. While an aircraft doesn't take a whole year to get assembled, the parts have been in the pipeline for much longer. So even if every thing's ready to go at this very moment, nothing is coming off that line for at least a year and half. Think about how long it took ARJ-21 to get from initial assembly to finally rolling off the line.

Can China make a copy of IL-76 with the blueprints from Uzbekistan? Sure they can, it probably will turn out even better than the original, ala J-11B. But it most definitely will not, under any circumstances, happen in 1-2 years time frame. That's the problem I have with your statement.

WS-13 getting Russian support? You think the Russians are that stupid to help China make a product that will eliminate that market. Who said copying D-30? Their own high bypass engine has been working on for a few years now, it's already conducting flight tests. And add to that, if you've read about the progress of WS-15 and improved WS-10A, you'd know that they are capable of developing engines much faster in the old days.

The Russians certainly don't control the Kazakhs. As for Russian cutting China off, that's a really interesting point, because Russians have accused China of copying them for years, yet they are still trying to sell more to China.

That's rubbish, I have a kanwa interview with Vegas who said they never assisted China will the IL-76 conversion for KJ-2000 platform. The original one that Israel fitted was using an A-50 airframe. And A-50 was already modified by the Russian from IL-76 for AWACs purpose. Vega stated they were extremely surprised by the amount of modification China put in.

you are talking about materials that were developed back in the days, so the current technology level in China is greater than that. You are talking about old manufacturing process that China would be able to improve on. You are talking about parts that China can built themselves or buy from all the previous Soviet republics. Case in point, Russians haven't stopped sourcing parts for J-11B, have they?

let's put it this way, I personally don't expect China to go for IL-76, because it's technology is pretty old. I think they are going for their own transport. Even that I think will be ready by 2015, which is faster than your time frame. China would only go for something like IL-76 if they can get it done far faster than their own transport. Remember, military transport doesn't have to worry about passing FAA and even their airline project (which is planned to get that) is expected to be finished before 2020. So, my problem with what you said is that China is not capable of getting IL-76 copied in a speedy timeframe.

Re: China's transport plane capacities

Russian cutting supplies off to China, well no it aint gonna happen anytime soon. But if it does China just shrugges it off and keeps going, but then Russia is in financial burden without Chinese arms purchase to keep funding their facilities.

IL-76 to KJ-2000 conversion had no outside help whatso ever. Sure they might of had influence but no blueprints or advising or information was given nor did China need it.

This engine problem demon China HAD in the past is diminishing every year, and or so months. Long list of China turbofans/turbojets ranging from fighter, bomber, transport, cruise missles, BVRAAM, SRAAM, SAM equipped.

Any project takes awhile from your previous severeal post it seems that it sounds that your saying China is moving slow compared to other nations in aviation development. Well any project takes awhile when its an aerial platfrom. It aint waving a wand.

And add to that, if you've read about the progress of WS-15 and improved WS-10A, you'd know that they are capable of developing engines much faster in the old days.
Russians offers help with WS-13 because that's the only way to get any order from PLAAF. PLAAF weren't high on FC-1 anyway, a Russian engine will kill it. That's why WS-13 was developed. For Klimov, helping with WS-13 is very logical, getting only a piece of the pie is better than having none at all.

As for China's own "high bypass turbofan", that's nothing but vapor ware. If they have it already, then the new Large aircraft project would not have included the need to develop China's own high bypass turbofan. WS-15 is pretty much in the same category as it's just RUMORED to be developed and has years to go before even turned on for the first time. WS-10A is low bypass engine designed for fighters and it's thrust is not enough when compared to D-30.

The Russians certainly don't control the Kazakhs. As for Russian cutting China off, that's a really interesting point, because Russians have accused China of copying them for years, yet they are still trying to sell more to China.

Russians don't control them. But most of the parts are produced in Russia, and the Russian government certainly controls those. Plus, the factory wanted to sell blueprints precisely because Russia had cut off their supplies of parts and support, so how are they going to help China getting parts when they can't do that themselves?

That's rubbish, I have a kanwa interview with Vegas who said they never assisted China will the IL-76 conversion for KJ-2000 platform. The original one that Israel fitted was using an A-50 airframe. And A-50 was already modified by the Russian from IL-76 for AWACs purpose. Vega stated they were extremely surprised by the amount of modification China put in.

That IL-76 Phalcan were constructed from a stock IL-76 airframe, using a plan modified from basic A-50 setup, but not modified from an existing A-50. It's hard to imagine China not had at least some liaison officers in Russia to observe the modification process and reviewing the plans. So China definitely had the technical information on how that modification took place. But just for the sake of argument say they DIDN'T get it. The Israelis deal were canceled in year 2000, and KJ-2000 was flying at around 2006 or 2007. That's 6 years from start of project, assuming they only started it AFTER the cancellation of Phalcon, to an actual example flying. That's 6 years to complete the modification project, using all those modern equipment you were talking about, and using experience gained through servicing them and operating them. Don't you think setting up a complete new production line would take just as long, if not longer than a modification project?

you are talking about materials that were developed back in the days, so the current technology level in China is greater than that. You are talking about old manufacturing process that China would be able to improve on. You are talking about parts that China can built themselves or buy from all the previous Soviet republics. Case in point, Russians haven't stopped sourcing parts for J-11B, have they?

Again, J-11B is a sanction modification as permitted in the original purchasing contract for Su-27. It's flying only some 15 years after the start of license production agreement, where the Russian provided all the technical document, production tooling and 100% of parts initially needed to produce and service Su-27, and provided assistance each step of the way until SAC mastered the skills needed to produce them. Surely that proves that China can copy IL-76 within 2 years after receiving blueprints and production documents? :rolleyes: I think not.

let's put it this way, I personally don't expect China to go for IL-76, because it's technology is pretty old. I think they are going for their own transport. Even that I think will be ready by 2015, which is faster than your time frame.

Yet again, you have no proof behind your conclusion, and it doesn't fit China's track record. Take ARJ-21 for example, the project started in 2002, and even with all the assistance from foreign companies on ALL the critical subsystems, (Antonov on the wing, GE on the engine, Rockwell (or was it Honeywell) on the avionics), using existing production tooling left from MD-90 project, the first flight of the prototype is only going to take place by March of this year. That's six years from start of project to first flight. Yet you believe that on a much more complex project (the new large transport), without foreign help from the West(since military project can't receive their help), it's going to take shorter time than the much simpler ARJ-21. Let's put it this way, it's NOT going to happen.

China would only go for something like IL-76 if they can get it done far faster than their own transport. Remember, military transport doesn't have to worry about passing FAA and even their airline project (which is planned to get that) is expected to be finished before 2020. So, my problem with what you said is that China is not capable of getting IL-76 copied in a speedy timeframe.

I think you just refuted your own statement here. China would go for IL-76 only if can be done far faster than their own. So 2 years as stated by someone above and which you apparently agree to is not fast enough? Remember, that's 5 years ahead of your own very optimistic prediction on getting a new aircraft. So 5 years plus the track record of a mature design isn't as attractive as a new design. That could only mean one thing: There isn't too much time difference between copying IL-76 and getting a new design.

What an interesting remark...You are using Kanwa as a source?? Isen't Pinkov supposed to be platant china-hater who just advocates the china-threat concept and dishmisses every chinese efforts in the area of warfare? This is just weird...

...or could it be that he is a respectable source afterall?? But would it mean that Kanwa is right in its other statememts as well? What determines where Kanwa hits the right key? When it supports our own view and stand?? Makes me wonder:confused::confused:
