For the first time, my country has developed the jet trunk passenger aircraft C919, which has its own intellectual property rights, and has completed all airworthiness certification work in September 2022 and obtained the model certificate issued by the Civil Aviation Administration of China. It will be delivered to the first aircraft by the end of 2022. The successful development of the C919 large passenger aircraft and the acquisition of the model certificate marks my country's ability to independently develop world-class large passenger aircraft, and is an important milestone in the development of my country's large aircraft industry. This also means that passengers are one step closer to traveling on the domestically produced large plane C919.
After obtaining the model certificate
C919 also needs to obtain two certificates
C919 large passenger plane completed all airworthiness certification work in September this year and obtained the model certificate issued by the Civil Aviation Administration of China. Wang Yanan, editor-in-chief of "Journal of Aeronautics and Astronautics" and aviation expert at Beijing University of Aeronautics and Astronautics, said that this is an important moment for the C919, which was established in 2007, the first flight in 2017, and completed the five-year certification test flight:
Wang Yanan: C919 has been 12 years since the starting point of applying for airworthiness certification from the Civil Aviation Administration of China. The most important thing in the entire airworthiness certification work is to focus on model certificates, because nearly 300 flight test projects at more than 3,000 experimental points are all targeted at model certificates. The model certificate is actually a verification of the aircraft design and is aimed at this type of aircraft. Obtaining the model certificate of C919 means that the Civil Aviation Administration of China in accordance with its own safety regulations, which are the provisions of our Civil Aviation Administration Department 25, has recognized that the design of C919 complies with the safety standards implemented by the Civil Aviation Administration of China, and has proved that this compliance has reached a very good standard through test demonstration and analysis. This aircraft is qualified to be put into operation.
Wang Yanan introduced that after obtaining the model certificate, C919 will need to obtain two certificates:
Wang Yanan: For a civil aircraft, the model certificate is designed for the aircraft and is issued to the designer of the aircraft; the production license is targeted for the manufacturing facilities of the aircraft, which requires proof that the aircraft manufacturing facilities can produce more replicas according to the requirements of quality assurance, and have the same performance; Airworthiness Certificate is targeted at the individual aircraft after delivery, and is issued to the operator of the aircraft, that is, the airline, to prove that each aircraft individual is airworthy. When the aircraft obtains these three qualifications, it has the qualifications to be put into commercial operations.
When can passengers take C919?
From design, research and development, manufacturing to first flight, test flight, evidence collection, etc., the news about the domestic large aircraft C919 has attracted much attention from citizens:
Citizens 1: I have seen it when I read the news, and I must be looking forward to it very much!
Citizen 2: In terms of performance, hope it may be better than imported aircraft. In addition, in terms of seat design and ride experience, it can be further improved.
Citizen 3: In the past, I rarely paid attention to the model. I think I will consider C919 in the future and hope to sit on it earlier.
will deliver the first aircraft by the end of this year. As the world's first user of C919, China Eastern Airlines has stated that after the introduction of the first batch of five C919 aircraft, it will use Shanghai as the main base to encrypt routes such as Shanghai to Beijing Daxing, Guangzhou, Shenzhen, Chengdu, Xiamen , Wuhan, Qingdao and other routes. When can passengers take the C919 trip? Wang Yanan analyzed that:
Wang Yanan: If is flying after a certain demonstration, the time should be very short, because the previous certificate has been obtained. According to my own estimate, in the first quarter of 2023, some lucky passengers may take Chinese domestic large aircraft, and they are regular commercial flights. However, at the beginning, the scale and number of flights will be relatively limited and will gradually expand in the future.
C919 is the result of the efforts of several generations of aviation people
Domestic large aircraft have from scratch, embodying the efforts of several generations. Popular science writer Shoutuo said:
Shoutuo: Civil aircraft is a huge industry, with great global industrial value and a symbol of a country's comprehensive strength and integrity of the industrial system.Civil aviation people or our aviation people have always had a dream to let us Chinese take a large aircraft they developed. This process is very long and there are twists and turns in the middle. Since the 1970s, our country has tried to conquer it. So we finally have a large jet aircraft developed by C919 in accordance with internationally accepted airworthiness standards and has independent intellectual property rights, which is the result of decades of efforts by generations of aviation personnel.
C919 large passenger aircraft is the first jet trunk passenger aircraft developed by my country in accordance with internationally accepted airworthiness standards and has independent intellectual property rights. China Commercial Aircraft official website data shows that the C919 seats have a 158-168 seats, a standard range of 4,075 kilometers, and an increased range of 5,555 kilometers. Since its development,
has embarked on a development path of "Chinese design, system integration, global bidding, and gradually improving localization", and has conquered more than 100 technologies including integrated aircraft engine design, telex flight control system control law, active control technology, and refined finite element model analysis of the entire aircraft. Wang Yanan, editor-in-chief of "Aviation Knowledge Magazine", gave an example:
Wang Yanan: The overall design of C919 is the most critical intellectual property part of this aircraft. The entire appearance and structure of this aircraft are designed by us, and we have completed the manufacturing of the body and the manufacturing of large wings in structural manufacturing. The fuselage structure of large aircraft needs to take into account aerodynamics, strength, economy, service life and fatigue. China has solved these problems. Each of these points is a breakthrough in China's aerospace technology . Moreover, there are many sub-technology in China that are very highlighted, such as the friendly pilot human-machine interaction interface and a more comfortable cabin experience, which are some innovative techniques we have tried in the field of civil aircraft.
C919 has broad market prospects
Associate Professor of Economic Management Department of China Civil Aviation Management Cadres College said that C919 is benchmarked against Airbus 320 series aircraft and Boeing 737 series aircraft. C919 can adapt to market demand and has broad market prospects:
Xie Li: C919 basically covers the main routes in China, all within its range. The C919, Airbus 320, , Boeing 737, series belongs to the same type of model, and this type of model is the most owned model in the domestic and international markets of China and even in the future. So C919 should be said to be in a large demand, and only with demand can the development of manufacturing industry be promoted.
China Commercial Aircraft official website data shows that at present, C919 has a total of 815 orders from 28 customers. Popular science writer Shoutuo believes that:
Shoutuo: The world's civil aircraft industry has been relatively fixed for many years, and is under the big situation of the two giants of Boeing and Airbus . I think the production of C919 at this time by COMAC is a major change for the world's civil aircraft industry structure. Our C919 future is worth looking forward to. What role will COMAC play in the future world civil aircraft industry, and what role will our domestic aircraft play in the future world civil aviation landscape? These are all worth looking forward to.
data shows that 22 provinces and cities, more than 200 enterprises, 36 universities, and hundreds of thousands of industrial personnel in China participated in the development of the C919 large passenger plane. Wang Yanan, editor-in-chief of "Aviation Knowledge Magazine", believes that C919 ushers in new opportunities for the entire industrial chain:
Wang Yanan: After the aircraft is put into operation, all the supply chains participating in this aircraft have obtained excellent qualifications to compete in the global aviation industry. Moreover, with the improvement and modification of C919 afterwards, the entire industrial chain will be pulled. Not only are these manufacturers being driven, but some basic research, such as materials, chemicals, textiles, electronics, and aerodynamics, will be positively affected by C919. Through the large aircraft project, China's civil aircraft industry, aviation industry, and national science and technology industry structure will be driven, which is the value of the C919.
