How about our domestically produced large aircraft?

Large aircraft are no less than the "two bombs and one satellite" and a major scientific and technological project of manned spaceflight, and they also have a more direct and direct relationship with the lives of ordinary people. In today's world, only the United States, Russia, and the European Union can master the technology of manufacturing large aircraft, and only the Boeing aircraft of the United States and the Airbus aircraft of the European Union have international competitiveness, which is even less than the number of countries with nuclear and aerospace technology. The large aircraft project is not only a technical force issue, but also a more important market environment issue, especially the aviation license issue.

Some developed countries, such as Japan, Sweden, Israel, etc., are not without potential strength for research and development from a purely technical point of view. However, due to its small land area and its own independent aviation market, if it does not get the aviation license of a big country, the large aircraft built can only be a high-end toy placed in its own square. China has a vast territory, and there is also a market demand that is expanding rapidly, and no matter whether foreign countries give aviation licenses or not, there is enough room for use.

Moreover, we can clearly see from Premier Wen's article that if China does not develop large aircraft, it will go to a high level of competitiveness in the international market. It is foreseeable that the future of domestic large aircraft should be at the level of Boeing and Airbus in terms of safety, economy, comfort, environmental protection and other aspects. Wish.

The domestic large aircraft shows its strength, and its performance "catches up" with the United States, breaking the monopoly of Boeing and Airbus!

Judging whether an aircraft is domestically manufactured usually depends on three criteria, namely, the ownership of the whole aircraft, the core team that develops the whole aircraft, and the key links in the development of the whole aircraft. The property rights of the C919 belong to COMAC, and the development is based on the team of COMAC, and the key links such as aircraft design, flight test, and sales are in the hands of COMAC.

Looking at the development and production units of the main systems and large parts of the first C919 aircraft, AVIC or COMAC have participated in the development of avionics, flight controllers, and engines at the core of the aircraft. "COMAC puts forward requirements and specifications to all system manufacturers, so that they can develop them according to our requirements. We use global resources, but the overall technology is in our own hands. Wu Guanghui said.

The engines of the 919 aircraft are not made in China.

The engine of the C919 aircraft was developed by the United States General Electric (GE) and the French company Safran.

The C919 aircraft engine model is a twin-engine turbofan medium CFM LEAP-1C engine.

On December 21, 2009, COMAC and CFM officially signed a letter of intent for strategic cooperation in the power plant of C919 large passenger aircraft in Beijing, and selected the LEAP-X1C engine developed by CFM as the starting power plant of C919 large passenger aircraft.

On July 22, 2015, CFM International's first CFMLEAP-1C engine was delivered to COMAC's manufacturing center in Pudong.

Review the history of C919 and the principle of the engine, and briefly describe the history of China's development of domestic large aircraft.

Summary. The domestic large aircraft is produced by Shanghai Aircraft Manufacturing. Shanghai Aircraft Manufacturing Co., Ltd. is mainly responsible for the mass production of ARJ21 aircraft, C919 large passenger aircraft and CR929 wide-body passenger aircraft with independent intellectual property rights in China.

The domestic large aircraft is produced by Shanghai Aircraft Manufacturing. Shanghai Wang Chong Aircraft Manufacturing Co., Ltd. is mainly responsible for the development of ARJ21 aircraft with independent intellectual property rights, C919 large passenger aircraft and CR929 wide-body passenger aircraft.

Shanghai Feida Luwu Machine Manufacturing Co., Ltd. focuses on the research and development of high-precision positioning technology, and provides precise location information services for government and enterprise customers.

Before Li Dan, Shanghai Aircraft Manufacturing Suidong ****ARJ21 aircraft entered the mass production stage, and the C919 large passenger guess disturbance aircraft also started normal passenger operation on May 29.

At 12:31 on May 28 this year, flight MU9191 of Dongfang Airlines, operated by a C919 large passenger aircraft, landed smoothly at Beijing Capital International Airport.

On May 28, COMAC, the manufacturer of China's domestically produced C919 aircraft, posted on its official Weibo to congratulate China Eastern Airlines on the successful operation of the world's first C919 passenger aircraft. China's civil aviation industry has also turned a new page. C919 is developed in accordance with international civil aviation regulations, has independent intellectual property rights, focuses on meeting the needs of domestic and foreign large-volume and medium-volume markets, with 158-168 seats and a range of 4075-5555 kilometers.

The name of China's domestic large aircraft is C919.

The first domestic large passenger aircraft C919 - naming rules: C919C is the first letter of China (China), the meaning of the first "9" is eternity, "19" represents the maximum passenger capacity of 190 seats, and the future model may also be named "C929".
