Fengkou Finance reporter Liu Jian

On the morning of September 13, the two C919 passenger planes flew from Shanghai to Beijing Capital Airport with the registration number B-001F and B-001J. The two C919 passenger planes flew to Beijing, mainly preparing for evidence collection. This means that C919 is one step closer to commercial operations.

At present, the C919 passenger plane has completed the five -year evidence collection test flight. It is waiting for the certificate of the model to obtain evidence as soon as possible.

As a large -scale jet civil aircraft developed in accordance with international civil aviation regulations and has independent intellectual property rights, C919 may drive the trillion yuan market, and its industrial chain will also be developed rapidly.

What are the characteristics of C919? What are the basic parameters? How many customers are currently? Take a look.

It is expected to obtain a certificate this month

C919 large passenger aircraft have always been hot topics in our civil aviation community. Public information shows that C919 has been developed in 2008 and is produced by COMAC. The total assembly is offline on November 2, 2015. The first flight was successful on May 5, 2017, and then officially entered the stage of test flight obtaining evidence. In the five years, the six C919 aircraft have carried out test flights for different subjects in many places in China.

Evidence collection is the prerequisite for aircraft delivery. After obtaining the model certificate (TC), the C919 aircraft can be delivered to customers. Today, the two C919 passenger planes took off from Shanghai to Beijing to prepare for evidence collection. According to the internal personnel of the Corporation of Corporation, C919 is expected to obtain a certificate in September. Industry insiders said that C919 may obtain a certificate issued by the China Civil Aviation Administration on September 19.

With the airworthiness certification of the Civil Aviation Administration of China, the new aircraft can operate in China in China. At the same time, my country has signed 204 bilateral airline agreements with 27 countries and regions, including Canada, Brazil, New Zealand, Australia, Russia, etc. This means that my country's C919 can be operated not only in China, but also in these countries and regions.

Design economic life 80,000 flight hours

According to the information of China Commercial Flying's official website, C919 large passenger aircraft are large jet civil aircraft developed by China in accordance with international civil aviation regulations and have independent intellectual property rights. They have 158-168 seats and 4075-5555 kilometers.

C919 is a narrow -body trunk passenger aircraft, which is designed for short -range to medium -range routes. Among them, C is the first letter of China, and it is also the first letter of the Chinese Shangfei English abbreviation. The first "9" means long -lasting, and "19" represents the maximum passenger capacity of 190. The standard range is 4075 kilometers, the maximum voyage is 5555 kilometers, the design economy is 80,000 flight hours, the maximum business process is 18900 kg, and the unit price is about 653 million yuan.

Examination test flight, verification safety

The development of the C919 large passenger aircraft project adheres to the principles of safety first and steadily advanced. A total of 6 C919 test flight aircraft are put into the test flight work, respectively in Yanliang, Nanchang, Jiangxi, Dongying, Shandong, Inner Mongolia, Xilinhot, Xinjiang Turpan, Dunhuang, Gansu, and other places. Complete important test flight subjects such as tremor/pneumatic servo elasticity, stall, air -speed calibration, high temperature, high and humidity, and full machine drainage; conduct a series of ground verification tests, R & D test flights, and indicate compliance test flights, power devices, flight control, flight control The system, hydraulic landing gear, avionics and electrical systems have been verified; all the full machine static tests including the 2.5G limit load static test have been completed, laying the foundation for the approval test flight.

The test flight is an important part of the new passenger aircraft model and evidence collection work, and it is one of the important methods that indicate that the aircraft design meets the requirements of the availability clause. Through test flight to verify the design ideas and technical routes of the aircraft, it shows that the safety and reliability of the aircraft meets the requirements of airworthiness. 6 trial aircraft to complete all the test flights is an important stage victory for the development of the C919 large aircraft project.

It is reported that the C919 has a total of more than 700 test flight subjects, and invested 6 aircraft for all scientific research and evidence collection test flights. It is planned to complete the entire test flight task of 4,200 hours and 2282.

More than 200 companies participate in the development

According to the China Commercial Fei, more than 200 provinces and cities, more than 200 enterprises, and 36 universities in China participated in the development of the C919, and 16 material manufacturers and 54 standard parts manufacturers became suppliers or potential suppliers of the project. It also signed a strategic cooperation agreement with six central enterprises including AVIC to establish a strategic cooperation relationship with 7 major banks.

According to public information, the C919 industrial chain includes design and development, advanced manufacturing (new materials, components, body manufacturing, airborne systems, general installation integration), operation and maintenance, etc. According to the data, the nine sections of the nine segments such as C919's first aircraft, front fuselage, middle body, central wing, and middle and back fuselage were manufactured by domestic aviation industry enterprises such as AVIC, Chengfei Minfu, Shenfei Minfan, and other domestic aviation industry enterprises. Many A -share companies such as AVIC, China Aviation Optoelectronics, AVIC, AVIC, Boyun New Materials, and Lijun shares participated in it.

As the only manufacturer of large military aircraft in my country, AVIC has long been involved in the development of C919. Its China Aviation Optoelectronics is the only qualified supplier of C919's aircraft installation stand; Zhonghanghan Shengsheng, a subordinate joint venture of AVIC Mechanical and Electrical, manufactured and manufactured power systems. ) Provide commercial aviation power products; AVIC Electronics in May 2014 disclosed that the company's subsidiary Shanghai Airlines has undertaken the task of independent development and batch delivery of C919 control board components, lighting control systems and integrated circuit breaker boards; AVIC The aircraft disclosed in the 2016 annual report that the company's aircraft parts products mainly include the ARJ21 turbofan branches of the aircraft front fuselage, middle body, wing, front landing frame and other core components, C919 large passenger aircraft fuselage, wing and other key components , Other domestic models landing racks and wheel brake systems, as well as related products of international transfer business. Hongdu Airlines disclosed in the 2016 annual report that as the only supply provider such as the C919 fuselage, the company has delivered high -quality front body and middle and rear fuselage products since 2014. In addition, Aerospace Electromechanical disclosed in the 2016 annual report that the company and COMAC were carried out research and development in the rear pressure box, spoiler joint, grille, engine blades and other structural parts, respectively.
