The domestic C919 aircraft successfully completed its first flight, from the C919 project, to the launch in 2015, and then to the first flight. All parties were discussing around this domestic aircraft. Since the beginning of April, CCTV news channel has been collecting questions on the Internet through CCTV News new media channels. Netizens have mentioned the most and most acute issue, which is about C919 engine, c919 is called a new generation of jet trunk passenger plane with independent intellectual property rights of Chinese people, so is its engine made in China? Can the whole plane be made in China? Next, follow CCTV reporters into China shangfei to find the answer.
CCTV reporter Zhao Zhongliang: when it comes to understanding the C919, a large domestic plane, many netizens point to its engine. Everyone is saying, is this engine made in China? If it comes from international suppliers, can it be said that C919 is a large plane independently developed by our country? Today we will answer this question. Yes, the C919 engine is provided by international suppliers. It is the latest generation of LEAP engine developed by General Electric and French saifeng company. The performance of this engine is very excellent, and the thrust can reach 13 tons. Interestingly, when C919 selected this engine, the Boeing 737MAX corresponding to C919, airbus 320Neo’s latest aircraft were all replaced with this engine, which can be said to have changed the engine market of trunk passenger aircraft at that time.
CCTV reporter Zhao Zhongliang: in fact, the use of engines from international suppliers for civil airliners is a very common choice for the world aviation industry. I am currently located in the China headquarters of GE, one of the three major international aviation power suppliers. Here we know that actually C919 in China, Boeing in the United States, Airbus in Europe, bombardier in Canada and Brazilian aviation industry in Brazil are actually using engines from international suppliers. What you see now is the GEnx next generation new engine provided by General Electric for Boeing 787. In fact, the engine used by our C919 is also the latest generation engine jointly developed by General Electric and French saifeng. But as a result, we have another problem. Since the engines we choose are basically the same, will the performance of the aircraft be the same?
? CCTV reporter Zhao Zhongliang: in fact, to figure out this problem, we must start from the design of the aircraft. The engine of the aircraft was determined at the beginning of the aircraft design. This is the original birthplace of C919 design. At that time, after confirming the aircraft engine, we began to carry out another work, you should know that the engine is not like a light bulb. You can use it after buying it and screwing it. The docking between it is very complicated. The digital model on the computer screen we see now is the part of the aircraft engine and wing docking. We print out the relevant documents of this digital model, this is actually a part of the docking documents jointly completed by C919 designers and engine companies, which are only about one third. Therefore, it can be seen that this engine also has the painstaking efforts of Chinese people. In the aviation field, an aircraft will normally be equipped with two-type engines. With such efforts, C919 is also equipped with the interface for the future docking of China’s autonomous engine Yangtze River 1000A. I believe that one day, our domestic big planes will also be able to use the Chinese heart.
