2023年5月28日是一个值得被记住的日子，国产大飞机C919全球商业首飞成功。中国东方航空公司使用C919执行MU9191航班，从上海虹桥机场飞往北京首都机场。从今往后，旅客将可以乘坐国产大飞机出行。国际大飞机市场，进入ABC时代。

中国国产大飞机国产率高达60%

C919商业飞行成功，标志着中国成为世界第三个可以制造大飞机的经济体。目前拥有干线飞机生产能力的航空公司有美国的波音、欧盟的空客和中国的商飞。能生产大型支线客机的有加拿大德哈维兰、巴西航工、俄罗斯联合飞机和中国商飞。日本三菱曾经在76-88座系列的支线客机领域投入过大量资金，该项目于2023年2月7日宣布失败。所以，中国也是整个东亚地区唯一一个拥有大飞机生产能力的国家。

值得一提的是，中国的C919干线飞机国产率高达60%。作为对比，美国的波音客机和欧盟的空客，不同客机的国产率也仅仅维持在40%至70%之间。由此可见，中国在大飞机领域的自主研发实力还是非常值得肯定的。

俄罗斯曾经拥有大飞机的制造能力，也是唯一有可能实现大飞机100%国产率的国家，但是由于经费问题，俄罗斯目前暂时无法生产自己的大飞机。所以，大飞机的生产不仅仅是技术实力的象征，同时也是一个国家经济实力的彰显。

C919飞机外壳蕴含黑科技

记得我在读高中的时候，化学课上老师就介绍过中国的大飞机研发，让我印象非常深刻。中国80年代就尝试过民用大飞机的研发，也就是运-10。这款大飞机是模仿美国波音707，对其进行逆向工程的，期间进行过100多次试飞，但是最终项目终止。

当时中国输在哪？就是输在飞机外壳的航空材料科学上。飞机外壳材料需要有稳定性、柔韧性、质量轻这些特点。当时我们国家的材料科学还没有现在这么发达，导致运维成本过高。

C919的飞机外壳技术蕴含黑科技，完全自主研发，采用了大量的钛，保证的飞机结构的稳定性，反复飞行不会发现形变。大大降低了运维成本，保证了安全性。西方航空工业可以卖给我们发动机，但是绝不会给我们提供飞机外壳原材料合金。所以，我国的客机人员，攻克了大飞机生产的最重要一关。

C919安装了国产北斗定位系统

C919总设计师吴光辉曾经在南航课堂介绍过C919航电系统的黑科技。

在飞行操控方面，C919加入了大量自动化和边界保护技术，如果飞行员在飞行中误操作，飞机可以进行自主纠错，最大限度地把事故发生率降到最低。

C919上还安装了中国自主研发的北斗卫星导航系统，飞行途中除了进行导航以外，黑匣子还可以和卫星进行实时通讯，自动发报飞机上的各种参数。

世界航空大飞机市场进入ABC时代

以前世界大飞机市场只有欧盟空客Airbus代表的A和美国波音航空Boeing代表的B。C919飞机首字母的C，代表着中国China。中国大飞机C919首飞成功标志世界航空大飞机市场进入ABC时代。

英文版：The first flight of China's C919 was a success, achieving a 60% domestic production rate. The global aviation industry has entered the era of ABC

May 28th, 2023 is a memorable day as it marks the successful global commercial maiden flight of China's domestically produced C919 aircraft. China Eastern Airlines operated the MU9191 flight using the C919 from Shanghai Hongqiao Airport to Beijing Capital International Airport. From now on, passengers will be able to travel with domestically manufactured large aircraft. This signifies the beginning of a new era in the international large aircraft market, ushering in the ABC era.

The domestic production rate of China's domestically produced large aircraft is as high as 60%.

The successful commercial flight of the C919 marks China as the third economy in the world capable of manufacturing large aircraft, alongside Boeing of the United States and Airbus of the EU. Amongst airlines with the ability to produce large regional jets are Canada's De Havilland, Brazil's Embraer, Russia's United Aircraft Corporation, and China's Commercial Aircraft Corporation (COMAC). In the past, Japan's Mitsubishi invested heavily in the production of regional jets with a capacity of 76-88 seats, but the project was declared unsuccessful on February 7th, 2023. Therefore, China is now the only country in East Asia that possesses the capability to produce large aircraft.

It is worth mentioning that the domestic production rate of China's C919 airliner is as high as 60%. By comparison, the domestic production rate for different types of Boeing planes and Airbus planes is only maintained between 40% to 70%. Hence, the independent research and development strength of China in the field of large aircraft is very commendable.

Russia used to have the capability to manufacture large aircraft and was the only country that could possibly achieve 100% domestic production rate for large aircraft. However, due to funding problems, Russia is currently unable to produce its own large aircraft. Therefore, the production of large aircraft not only symbolizes technological strength but also serves as an embodiment of a country's economic might.

The C919 aircraft's outer shell contains high technology.

I remember in high school, my chemistry teacher introduced China's development of large aircraft in class, which left a deep impression on me. In the 1980s, China attempted to develop a civilian large aircraft, namely the Yun-10. This large aircraft was developed through reverse engineering of the American Boeing 707 and underwent over 100 test flights but was eventually terminated.

At that time, where did China fail? It was the aerospace material science related to the aircraft's outer shell. The material for the aircraft's outer shell needs to possess stability, flexibility, and light weight. At that time, China's material science was not as developed as it is now, resulting in high maintenance costs.

The technology of the C919 aircraft's outer shell contains black technology which has completely been independently researched and developed. A large amount of titanium is used to ensure the stability of the aircraft structure, and no deformation is found during repeated flights. This greatly reduces operating costs and ensures safety. Western aviation industries can sell engines to China, but they will never provide China with aircraft shell raw materials alloys. Therefore, China's aviation personnel have overcome the most important bottleneck in the production of large aircraft.

The C919 is equipped with domestically produced Beidou positioning system.

C919 chief designer Wu Guanghui once introduced the black technology of the C919 avionics system in a class at Southern Airlines.

In terms of flight control, the C919 has incorporated a large number of automation and boundary protection technologies. If the pilot makes an error during flight, the aircraft can autonomously correct it, minimizing the accident rate.

The C919 is also equipped with China's independently developed Beidou satellite navigation system. During flight, in addition to navigation, the black box can also communicate in real-time with satellites and automatically report various parameters of the aircraft.

The world's aviation market for large aircraft enters the ABC era.

Previously, there were only representatives of A from Airbus of the European Union and B from Boeing of the United States in the global market for large aircraft. The letter C in the initialism C919 stands for China. The successful maiden flight of China's large aircraft, the C919, signals that the world's aviation market for large aircraft has entered the ABC era.
