2023年5月28日是一個值得被記住的日子霹购，國產大飛機C919全球商業(yè)首飛成功佑惠。中國東方航空公司使用C919執(zhí)行MU9191航班，從上海虹橋機場飛往北京首都機場齐疙。從今往后膜楷，旅客將可以乘坐國產大飛機出行。國際大飛機市場贞奋，進入ABC時代赌厅。
中國國產大飛機國產率高達60%
C919商業(yè)飛行成功，標志著中國成為世界第三個可以制造大飛機的經濟體轿塔。目前擁有干線飛機生產能力的航空公司有美國的波音特愿、歐盟的空客和中國的商飛。能生產大型支線客機的有加拿大德哈維蘭勾缭、巴西航工揍障、俄羅斯聯合飛機和中國商飛。日本三菱曾經在76-88座系列的支線客機領域投入過大量資金俩由，該項目于2023年2月7日宣布失敗毒嫡。所以，中國也是整個東亞地區(qū)唯一一個擁有大飛機生產能力的國家采驻。
值得一提的是审胚，中國的C919干線飛機國產率高達60%匈勋。作為對比，美國的波音客機和歐盟的空客膳叨，不同客機的國產率也僅僅維持在40%至70%之間洽洁。由此可見，中國在大飛機領域的自主研發(fā)實力還是非常值得肯定的菲嘴。
俄羅斯曾經擁有大飛機的制造能力饿自，也是唯一有可能實現大飛機100%國產率的國家，但是由于經費問題龄坪，俄羅斯目前暫時無法生產自己的大飛機昭雌。所以，大飛機的生產不僅僅是技術實力的象征健田，同時也是一個國家經濟實力的彰顯烛卧。
C919飛機外殼蘊含黑科技
記得我在讀高中的時候，化學課上老師就介紹過中國的大飛機研發(fā)妓局，讓我印象非常深刻总放。中國80年代就嘗試過民用大飛機的研發(fā)，也就是運-10好爬。這款大飛機是模仿美國波音707局雄，對其進行逆向工程的，期間進行過100多次試飛存炮，但是最終項目終止炬搭。
當時中國輸在哪？就是輸在飛機外殼的航空材料科學上穆桂。飛機外殼材料需要有穩(wěn)定性宫盔、柔韌性、質量輕這些特點充尉。當時我們國家的材料科學還沒有現在這么發(fā)達飘言，導致運維成本過高。
C919的飛機外殼技術蘊含黑科技驼侠，完全自主研發(fā)姿鸿，采用了大量的鈦，保證的飛機結構的穩(wěn)定性倒源，反復飛行不會發(fā)現形變苛预。大大降低了運維成本，保證了安全性笋熬。西方航空工業(yè)可以賣給我們發(fā)動機热某，但是絕不會給我們提供飛機外殼原材料合金。所以，我國的客機人員昔馋，攻克了大飛機生產的最重要一關筹吐。
C919安裝了國產北斗定位系統(tǒng)
C919總設計師吳光輝曾經在南航課堂介紹過C919航電系統(tǒng)的黑科技。
在飛行操控方面秘遏，C919加入了大量自動化和邊界保護技術丘薛，如果飛行員在飛行中誤操作，飛機可以進行自主糾錯邦危，最大限度地把事故發(fā)生率降到最低洋侨。
C919上還安裝了中國自主研發(fā)的北斗衛(wèi)星導航系統(tǒng)，飛行途中除了進行導航以外倦蚪，黑匣子還可以和衛(wèi)星進行實時通訊希坚，自動發(fā)報飛機上的各種參數。
世界航空大飛機市場進入ABC時代
以前世界大飛機市場只有歐盟空客Airbus代表的A和美國波音航空Boeing代表的B陵且。C919飛機首字母的C裁僧，代表著中國China。中國大飛機C919首飛成功標志世界航空大飛機市場進入ABC時代慕购。
您也會期待乘坐中國自主生產的大飛機出行嗎锅知？
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.
Are you also looking forward to traveling on Chinese-made large aircraft?
