中國研製大型客機計劃

中國人要用國貨 ~~~

如果國產 o既 飛機
可以有 Airbus 及 Boeing o既 質數 , 咁就唔怕 o既 ~~~

But it simply will not happen in that timespan. The aerospace industry in China simply has not
got the know-how of various critical technology and knowledge to match Boeing or Airbus. For
a start, China has not got a matured composite manufacturing capability, which Europe and the
US have already achieved for what, 30+ years. It may turn out being cheaper to develop and
build, but the operational cost will be very unfavourable, esp. if a locally developed engine is
selected, that pushing its whole life cost beyond competing western products in the long run.

Unless CX and KA somehow get nationalised, the chance for them to acquire the mentioned
aircraft is as high as seeing a pig fly. I will not rule out that, at some point, chinese built aircraft
will make it to the fleet, but it will take such a steep learning curve for the chinese aerospace
industry just to catch up with their western rivals, let alone outmatching them. I quite agree
with 053h4 that it is a politically driven decision.

Above all though, I hope they do not end up just copying the Tu-204 or A320, which Airbus is
setting up a production line in China soon.

頭先睇新聞，俄羅斯想用IL-96為基礎，與中國合作研製大型飛機。
我就諗，如果此類機型研製成功，仲會唔會仲用四引擎呢？

我覺得如果俄方應該與中方合作，應該以AN-124為基礎，
將AN-124繼續改良，同波音/Airbus等貨機機型競爭，
反正而家Antonov無咩錢，想繼續建造AN-124/225新機都唔得，
AN-124本身又幾實用，中俄合作將佢發揚光大都唔錯。

所以還看我最尊敬ge共產黨人溫家寶總理可唔可以為中國帶來一點希望
一切都要由改變現在腐敗的中國政府開始

回覆 #13 volvo_chan 的帖子

如果講中俄合作,中國應該圖公司合作研製/改良現有ge飛機
雖然有部份組件都係來佬貨,但起碼叫做有個技術
我認為圖應該係可以發圍ge飛機製造商,佢現在欠缺ge主要都係錢泥開發
若然中國真係想完成大飛機哩個美夢
我覺得入股圖係一個唔錯ge方法
一泥可以幫圖更有potencial 去研製新飛機
又可以"抄考"下圖公司現時d技術用o係研製大飛機上
相信大家都明白"集思廣益"哩4隻字點解
就好似抄功課咁一定唔抄死同一個ge功課
應該哩度抄d果度抄d,之後再判斷一下d野岩唔岩
交比老師ge功課往往都會比"原裝者"好
唔知大家明唔明我講咩呢~

不過, 個人認為中國也"輸唔晒"
中國正牌重工業工業產品的質量也不算差
如做船業
而且中國有原整的航空工業

The quality of Heavy Industry in China? No comment  
The quality of the vessels built by China is improving, but "there are still lots of room to improve"

And, China didn't have "integrity" in aircraft industry
It lacks the ability to design and build aircraft electronic equipments and engines in the required mass production quantity and quality

中國高技術工人技巧高
也能運用各種設備

I think there are some boardmates often suffer from those "high-tech" workers

10年是一段很長的時間
大飛機的成敗同能否自行研發上述有高度可效性的設備有直接關係

10 years could be long time for human, but not a long time to draft, design and build a large aircraft

If they did use the Russian aircraft as the base design, I would recommend retaining the 4-engine design for safety reason

Although An-124 is a good freighter, that's not what China want.
At this moment, the target for China is a passenger aircraft

The problem is those parts are critical parts that China didn't have the ability to build it (in mass production scale)
Things like fuselage and wings would be hard to build, if China decide to use conventional material for most of the part

Copying...
In the current situation, China can be called as "student", while both US and the Europeans can be called as "teacher"
They are in a totally different level
The Europeans and US a great amount of money on the aerospace industry every year for more than a hundred years
Even you can copy, you can only copy what they look like, but not the "know-how" of building an aircraft, which is the most important thing...

為可說重工業無問題, 如造船工業的手工
船身建造非常光滑, 其質素同日本南韓相約
但電子系統國產只為約40%, 遠低於南韓日本

Well well......comments from the end-users aren't the same
The first two Ro-Ro ferries built for Sweden didn't receive good comment
And quite a lot of China vessels spent quite a long time after delivery, due to quality problem

And, smooth surface is only one of the very beginning step of building a good vessel

如果由零做起的確唔長
但無論相關的大飛機預研項目
如電腦設計, 大型發動機, 風洞測試數據, 機身設計, 相關生產設施
都有預研或在生產常應用中

I can tell you NO for the large aircraft engine
It is still quite hard for China to design and produce a large aircraft engine
That can meet the European/US standard on safety, quality and lifespan

為什麼中國的大飛機項目的客機, 不是貨機?
不是因為中國不需要貨機

但研制客機的原因, 是因其共通性
因各項電子或安全標準夠高
可把有關產品運用在各領域

China do need cargo aircraft, but it needs passenger aircraft more
Comparing the two markets, it's easy to find out the passenger aircraft demand is always higher than the cargo aircraft
Even cargo aircraft nowaday do need similar standard of equipments as those passenger aircraft also
