CCTV´s secret: why the Chinese C919 large aircraft used "foreign" | | | aircraft engine _ news
CCTV News: China´s C919 aircraft successfully completed its maiden flight from the C919 project, by 2015 line, then flew around the Chinese-made large aircraft, all parties in the discussions. And we most commonly mentioned was the most pointed, on the C919.

C919 has been called the Chinese intellectual´s next-generation jet airliner, then its engine is made in China, can the whole plane say made in China?
The C919 is an international supplier of engines, it is up to SAFRAN of France and General Electric of the United States company, developed the latest generation LEAP engine. This single engine performance was excellent, thrust can be up to 13 tons, and interesting is, when the C919 selection after the engine, and the Boeing 737MAX for C919, Airbus 320Neo the latest aircraft, switched the engine, can be said to change the airliner´s engines.

In fact, Jet engines use international suppliers, for the aviation industry in the world is a very common choice. China´s C919, America´s Boeing, Europe´s Airbus and Canada´s Bombardier and Brazil´s Embraer, in fact, these international suppliers of engines are developed. We´re seeing here is provided by GE for Boeing 787 GEnx engine of the next generation, our C919 engine is used by General Electric and SAFRAN of France developed the latest generation engines. But we have a problem, since the engine we have chosen are the same, the aircraft´s performance will be identical?
Aircraft engines aircraft design began to determine the beginning, here is a first C919 was born. We are on top of the computer screen´s model and is butt this part of aircraft engines and wings, this number we print it-related files, here is actually the C919 designer and engine company part of a completed dock files together, probably only about one-third. So you can see on this engine also has Chinese blood. In aviation, a normal aircraft will be equipped with two engines, and after such a hard C919 China engine was also equipped with the Yangtze River 1000A docking interface. Believe that one day, our Chinese-made large aircraft can also use Chinese heart.

国产大飞机C919为何选用“外国心”|发动机|大飞机|飞机_新闻资讯
央视网消息：中国国产C919大飞机顺利完成首飞，从C919立项，到2015年下线，再到首飞，围绕这架中国国产大飞机，各方都在讨论。而大家提到最多也是最尖锐的，就是有关C919发动机。

C919被称作是中国人自主知识产权的新一代喷气式干线客机，那么它的发动机是不是中国国产，整架飞机到底能不能说中国制造呢？
C919使用发动机是国际供应商提供的，它是由美国通用电气和法国赛峰公司合作，研发的最新一代LEAP发动机。这款发动机单台性能非常优异，推力可以达到13吨，而有趣的是，当C919选型这台发动机之后，和C919相对应的波音737MAX，空客320Neo型最新款的飞机，都换装了这款发动机，可以说是改变了当时干线客机的发动机市场。

其实，民航客机使用国际供应商的发动机，对于世界航空工业领域来说是非常常见的选择。实际上中国的C919，美国的波音，欧洲的空客，加拿大的庞巴迪以及巴西的巴西航空工业，其实这些研制方都在使用国际供应商的发动机。大家现在看到的是通用电气为波音787提供的GEnx下一代新型发动机，其实我们的C919使用的发动机也是通用电气和法国赛峰联合研发的最新一代发动机。但是这样一来我们又有了一个问题， 既然我们选择的发动机基本都一样，那么飞机的性能也会不会雷同呢？
飞机的发动机是飞机设计之初就开始确定的，这里就是C919设计的最初诞生地。我们现在看到的电脑屏幕上面的数模，就是飞机发动机和机翼对接的这部分，这个数模我们把它相关的文件打印出来，这里实际上就是C919设计人员和发动机公司共同完成的一部分对接文件，这些大概只有三分之一左右。所以可见这台发动机上同样有中国人的心血。在航空领域，一台飞机正常会配备两型发动机，而经过这样的努力，C919也同样配备了未来中国自主发动机长江1000A对接的接口。相信终有一天，我们的中国国产大飞机也能用上中国心。
