The First Domestic Large Aircraft Off The Assembly Line Helps China's Manufacturing Move Toward High-end
May 30, 2018

On November 2, the first aircraft of the Chinese-made large passenger aircraft C919 was unveiled.

    On the same day, in the factory building of Pudong Base, the newly built assembly production center of COMAC, the first C919 aircraft was displayed in front of the world as the curtain slowly opened. Liu Daxiang, a member of the National Large Aircraft Engineering Committee and an academician of the Chinese Academy of Engineering, described the situation on the scene to a reporter from the Journal of the People's Science of China: “The audience was applauded. Many people who participated in this assignment in the past seven years left tears of excitement.” Industry experts It is believed that the assembly of the C919 assembly line has profound implications for the development of China's civil aircraft industry, the improvement of basic industrial strength, and the development of a strong country. “It is an important milestone in the national large-scale aircraft project, which will help China's production toward the high end.” Liu Daxiang pointed out.

    C919 is our country's own planning, with its own independent intellectual property rights. Chen Yingchun, the executive deputy general planner of China Commercial Aircraft Co., Ltd.'s C919 project, described in an interview with the media. There are five signs for the autonomous development of the C919 aircraft, including the overall plan, aerodynamic shape, aircraft body planning and production, system integration and engineering. Project management, etc. “Starting from the first drawing, we have planned and produced it ourselves.” Liu Daxiang emphasized. “Independent development is the biggest highlight of large aircraft.” “As a civilian product, the C919 development team has acquired hydraulic systems and navigation systems from global procurement. Systems and equipment such as landing gear, brakes, and engines are integrated according to their own planning solutions, even for civil passenger airplanes from companies such as Boeing and Airbus, said Professor Huang Jun from the School of Aeronautical Science and Engineering at Beijing University of Aeronautics and Astronautics.

    The research and development personnel are highly conversed with regard to aerodynamic layout, structural data, and airborne systems, and completing the large-scale application of advanced data for the first time on domestic civil aircraft, and the development of millions of components and airborne systems. In the process of researching and setting up different industries, nearly 200,000 people participated in the development and production of the entire industrial chain. The adoption of new technologies, new materials, and new processes has stimulated the development of China's economy and science and technology, progress of basic disciplines, and development of the aviation industry.

   Now, the C919 is characterized by “more secure, more economical, more comfortable, and more environmentally friendly”, and the cabin space has a greater advantage than competing models. The number of passengers at home and abroad is now 21, and the total number of orders has reached 517. Experts believe that the high-speed rail and nuclear power "going out" strategy has provided a model for large aircraft. “As with high-speed rail and nuclear power, cost advantages, core technologies, and high-quality services will be the core competitiveness of large aircrafts in the international market,” said Liu Daxiang.

    In addition, following the C919 large-scale passenger aircraft project will also launch avionics, flight control, hydraulic and other system experiments, airborne system integration experiments and the whole machine static experiments. The first aircraft is used as a test aircraft. Before the first flight, it is required to complete the commissioning of the system, flight test equipment, and instrumentation. The aircraft will fly first in 2016 as planned.
