Dear Maozedong:
First let me point out that this is a thread dedicated to the J-10 and not the J-12 or J-13. We should keep to the topic or address it in the proper thread. But since you opened this topic I will continue.
Regarding your desire for China to speed up its weaponry developement. Well, its much easier said than done. Weapons systems, like all modern technology require considerable expertise and skill. I think to a very large extent all of the news and shows about "young geniuses" tend to mislead a lot of people regarding how these things are made.
It may surprise you to learn that the best technical systems (civilian or military) are not made by the young designers. They are made by the "old" men (i.e. designers). And I really mean OLD men. I don't mean the fags who design clothing or watch bands, or the exteriors of cars or stereos. No, I mean mature experienced designers.
For example, you think its easy to design an engine? Lets try a car engine for example. One of the best (if not the best in my opinion) is Nobuhiko Kawamoto of Honda who is almost 80 years old. The former head (and founder) of Honda, Seichiro Honda unlike the Americans, did not want a "manager" to take over his company, he wanted an engineer! And not just any engineer, he wanted and engine man!
He selected Kawamoto himself as his successor. But first he gave him a little "qualification" exam. Backed by the resources of Honda Motorsports, Kawamoto had to prove himself in what is the most demanding of car engine developement environments - Formula 1. Kawamoto made the engines for team Mclaren - the Mclaren-Hondas.
He passed with flying colours - no less than six (6) Formula 1 engine constructors championships under his belt! Thats why he's head of Honda today and thats why they have such great engines. A contemporary of his is the head of Mazda motors engine design, Kenichi Yamamoto - the designer of the RX series of rotary engined sports cars.
Back in the 1960's Yamamoto heard that Felix Wankel had invented a new type of engine with a rotary piston, the so-called triangular epitrochoid. Yamamoto was very excited by it. He appealed to the German gov't and the Ambassador and bought a patent. What he and Mazda got for their money was a KKM lawnmotor motor and a set of plans. He immediately set about copying it.
As he put it "my first engine rattled like a tin can full of rocks, blew great clouds of white smoke and self-destructed in about 30 seconds!". In the course of engine developement he filled Toyo Kogyo's back yard with 6000 blown engines!
Thats that kind of commitment and dedication you need to get experience in all of this. And I guaranttee you that you will make mistakes, - its just that the old guys know what the limits are. Look at the age of the Chief designers of aircraft, ships, cars or even electronics, - case in point - Heard of Marty Cooper - of Motorola? He invented the cellphone back in 1979. And he's still inventing stuff - like the intelligent antenna array!
China destroyed a whole generation of design engineers during the Cultural Revolution. Making a great designer is like growing a great tree, it takes many, many years. You cut them down young and you have to start from scratch.
Hope this helps,
Best Regards
