Not anymore Read Tphuang blog He study aeroengine for a long time At least there are now 90 J11 which 200 WS 10A Engine . Sofar I haven't seen any report of accident
Please do not falsely accuse me of things that I did not say. I said imported 6 billion worth of CNC machines, not 8 billion only from Germany. There are many countries out there that have better CNC machines than the Chinese made ones. Just because the German made ones might be the best in the world, doesn't mean that the Chinese can only import from them. Japan is probably the biggest provider of CNC machines for China, if not, France and Italy also provide a lot of these machines. The US also provide a lot of them, but due to political sensitivity, many extreme high end machines are not for sale to the Chinese.
I also did not say that ballistic steel doesn't have to stand the heat. I meant it doesn't stand the heat for long. I repeated this multiple times already, if it's a material that only stands extreme heat and stress only for a short amount of time, it won't require that much experience to master. These things could usually be mastered within a short amount of time. These are dispensable materials, which are totally different from materials that have to stand stress for up to a decade or two. A lot of these long lasting materials are bottlenecks of Chinese industrial advancement. China make some of the best high tech parts in the world, but majority of them are disposable parts. If it is one of those long last parts instead, a lot would have to be imported. Like I repeated so many times, that's why ship engines and aviation engines have to be imported. Even after WS-10 entered service for quite a while, they just bought another 100+ batch of those Saturn AL-31 engines.
And as for those turbofans, lower performance and standards doesn't mean it's going to cause a plane crash. It is common sense that Russian engines are inferior to those American and British counterparts. But that doesn't mean Russian planes drop to the ground everyday. It simply means they have much shorter life span. In fact, the thrust vectored engines used on exported Indian Sukhois can only last as long as 30 work hours. The Chinese expertise is also a bit behind the Russians. For example, if the a normal Russian engine last 200 hours, the Chinese counterpart would probably be expected to last 150 hours.
If you really think that China already can produce carrier deck steels, please provide me with a link. At least so far, I have not seen any evidence of such accomplishment, but rather countless news reports saying that they are starting to tackle this problem. Also don't forget that as much as India suck in getting their job done, they are actually a relative key player in special grade steel production. They still imported few thousand tons of special grade steel in building their own aircraft carrier.
Don't forget, the carrier deck steels have to stand a cocktail of punishments, not just one or two. When these factors combine, the rules will change drastically. It is just like tank armour vs. agility. The addition of agility will compromise protection and more armour means lower agility. Carrier deck steels have to face even more factors. There are the heat from full afterburners, constant cooling from leaked steam and sea moisture, immense weight of fully loaded jets, the corrosion from sea salt, and on top of all these, the wear and tear from constant usage.
To be honest, even the Japanese, whom are considered to be experts in metallurgy and ship building, even they don't have the ability to make carrier deck grade steel. Even though they are trying very hard to breach the leash from Uncle Sam to have carriers, they still can't fly F35 from those "destroyers" even if they successfully bought them. The decks will simply not be able to support the weight of those jets. Dents will probably show after just a few months of usage.
PS: No offence, but please double check your grammar before posting, it is kind of mind boggling to read sometimes.
