Chinese Aviation Industry

I'd agree with you on this. J-10 no longer has to rely on AL-31FN, but everything else is valid. I wrote about it on my blog http://china-pla.blogspot.com
Basically, the issue is technology and manufacturing. They are weak on both right now. And they are almost incapable of producing large transport or even mass producing medium sized transport. Not exactly good signs for building a modern air force.

What do you think is China's best option for dealing with this?
Adopt a military-first approach where large-scale investments is made directly into expanding manufacturing capabilities for military aircraft and increasing military-related R&D (for fields such as material science and airframe)?
Pour massive amounts of resources into giving the commercial sector a much needed boost by aiming to attract a larger talent pool of AE, ME, and EE graduates and expanding commercial manufacturing capacity?
Provide indirect aid through subsidies and tax policies on a much smaller scale than direct investment (which seems to be the government's general across-the-board policy for dealing with the current economic situation)?

Also, how much do you think of a spillover naval-application materials science has? There was a thread on materials science that dealt with certain aspects of materials science development in China.

ps- great blog! Very informational- treasure trove of info!!

thanks.

I think everything is helping it. I would say what they are doing right now by pouring a lot of money into it + buying assets, investing in improving management practices, adopting western QA standard (like 6 sigma), buying the best possible machinery for production is the right way to go. Military research is obviously needed, but if you want to be able to consistently mass produce high quality aircraft, civilian production has to improve.

When people in China cease taking shortcuts whenever a problem is encountered, that would be an improvement.

It seems the military doesn't take short cuts. They certainly don't take short cuts in regards to the space program. The ones in China that take short cuts are the ones in the commercial sector that are out for a quick buck.

Well for their future fighter programs, they can't just buy a Russian engine any time they hit the wall with their own indigenous engin developments. So far they've been succesful with using existing technology to create capable platforms, but to be truly cutting edge they must be completely self reliant.

I'm not as confident as you are concerning the aviation industry, seeing China's impressive list of variants of J-8, Y-8, and H-6. J-8 first took off back in 1969, and over the past 40 years, the only major change it has was the switch from frontal intake to side intakes. Y-8 is now a 50 years old design and was first produced in China in 1972. After so much work in reverse engineering the design and spending three decades in building it, you'd think Shaanxi would know the design inside and out. Instead, they went straight to Antonov when modifying the design to Y-8F600. It has been six years and the other redesign of the Y-8 -- the Y-9 has yet to have a prototype in sight (unless they used up their only prototype on the ill-fate YJ-200). H-6 is basically the same situation, a 50 years old design which only recently has its major modification.

ARJ-21 is a kit bash of American's DC-9 body, with Russian Antonov designed wings, and American's GE engines.

It seems whenever they encountered a problem, a shortcut is taken, and by not solving the problem, the problem is solved.

Pardon, I misunderstood the context of "short cut" in this conversation.

Doesn't virtually every commercial aircraft manufacturer buy their engines from the reputable few that make them? Yeah for China they should completely be independent especially in regards to the military. But everyone in fact takes "short cuts" in this manner. The difference with China though as to say Japan is China knows the need to be independent while an allied country of the West doesn't place that as a priority.

I don't know where you got the idea that the wing is design by Antonov My understanding is Antonov did windtunnel peer review with 3 other windtunnel establishment. In engineering is quite common to do peer review Since Aerospace company in China capable of doing review on large plane is limited, they choose overseas partner I don't see anything wrong with that

Your critic is unwarranted because China didn't start in earnest of modernization until early 90's that is only 18 years. And for decade after that the budget for military are minimal because there are other urgent need. Only in the last 8 years is the budget growing at respectable pace

Let face it unless you have highly developed civilian technology you are not going to get sophisticated Military Technology. You should read the book by the designer of Leopard tank in which he said that after the war The German who designed the best tank has completely lost the ability to design tank .So he has to start from scratch but the German highly developed Automotive technology saved the day.

The same with China they have to start from scratch and if you watch the designer of JF17 and Space program They are all people in 30's and early 40's Give them some time they will matured

Now that they finally go through the process of designing J10 and JF17 I have no doubt that you will see original design in the future

China suppposedly began its next-gen fighter project in the late nineties- yet not even a full-scale mockup has been shown.

Wasn't it mentioned when it was announced that CAC had won over SAC in competition for the J-XX that both had to submit full-size scale mock-ups?

J-8 to upgraded to J-8H/F can launch BVRAAM, a major feat not just a small change. It doesnt matter about the years in service an aircraft is in, if its still capable then why replace it? Just cause some platform design was 40 years old doesnt mean the current ones in their inventory is still 40 year old technology. American superpower still uses B-52, C-130, F-16 and etc...

You cant snap your fingers and the problems is fixed. China has only has 8-10 years of decent funding and educated knowledge. Russia, Europe and Russia has had +40 years of knowledge of trial and error. Shortcuts let see Space Program, Satelitte, domestic GPS, telecommuncations, turbofan engines, munitions, etc....using technology thats already available off the shelf or on market speeds up development, and service time.

If you analyse the ARJ-21 as a DC-9 knock off, then if China develops something that can fly its a knock off, if it has 4 wheels and drives its a knock off. Obviously every nation that develops military hardware are exposed to certain foreign nations technology and will incorporate that into their own, not just China.

When designing a aircraft for the international market, it would make sense to offer a range of engine choices. Boeing do.

Designing aircraft isn't as easy as just canibalizing a lot of parts from various other aircraft and then just sewing them together into some kind of aerial Frankenstein's... sure, they might have studied existing parts for design inspiration, but a lot of engineering went into deciding how the parts on the thing should be modified and combined to create an aerodynamically sound and efficient design. Even if they have taken shortcuts on this particular project, the experience and lessons learnt will carry over to future projects.

Did you write a "research paper" before? What is yours?

You put anything of other people's together-it is yours!
