China defense industry faces homemade engine troubles

[Project 627]

we never compare J-20 with T-50 junk. we don't need a piece of joke to handle your crap.
J-20 is built to handle F-22 and F-35.

Please stop comparing J-20 to your improved Su-27 (akaT-50), show me some self respect please.

Junk!!! based on who's opinion, some funboy on a forum.

improved Su-27, hmmm and if you have any self respect back up your ridiculous clams with some FACT'S.

and their are estimates that the J-20 is big as the F-111, and if those estimates are true, then the J-20 cannot possibly be the same weight as the PAK FA.

Wikipedia is not a reliable source.

Size is not totally relevant to weight. That's why composites are used. And unless you have sources to prove that the J-20 indeed does weight heavier, that's not going to cut it.

How come Russia and USA's understanding concepts on engines issues in fast pace tracks while China longer process ?

China had a very weak and obsolete industrial base until 2000's, with very little funding for R&D. The economic rise had opened up ways for China to increase its pace, but we still have to play the catch up game.

Besides, we're not really that far behind. F110 engine on F-15 fighter jets took almost 10 years to sort out all of its problems. WS-10 only entered serviced in 2006.

Question: what makes large (20,000 lb +) high-bypass turbofans so difficult to master? Few nations are able to manufacture (let alone design) such engines, yet twice as many nations are making fighter engines. And one of them (Russia) is having a hard time selling them to commercial fleets abroad. Given Russia's poor market performance (compared to Western competitors), will China fare any better? Or will China settle for military applications only (future large transport), and forget about commercial profit?

China has good future potential. Even more so than Russia.

Although it still has to catch up to Western competitors, it can certainly be a player - both commercial and military. It's just a matter of time.

Developing an engine is five times more complicated than developing an airframe. I am sure given the speed at which china country is developing knowledge in the aviation field, it won't be long before we have a world class engine from the china.

Why do Chinese suppliers not just purchase the GE414 or the EJ200? HAL did it with the Tejas and I am sure Indian would cover a lot of technological innovation ground with these types of machines. I would not believe in European engines that much.

China is under a Western arms embargo.

Because of what crimes... ??

Supposed to be due to Tiananmen Square in 1989 but really they do not want China to reverse engineer their technology and catch up with them even quicker

I have read a similar article about the issue. Jet engine is one of the most sophisticated product that human race has achieved to produce. It has a very tough learning curve and it's not that easy to develop it in the first place. You can't come up with any expert who knows everything about a jet engine. It's a team work and each team focuses on different aspects of it. Each team member should be a specialist of a very specific part of it. Not any mechanical engineer with 20+ years of experiance can come and solve all of your problems. You need to prototype, collect data and prototype again. You should maybe cycle this for dozens of times.

In the end China will be able to do it. There is no speculation about that. But let's hope it will go in correlation with their deadlines. It's the bottleneck of Chinese aviation industry.
