The implementation of China's large aircraft project is steadily moving forward. The reporter learned from the relevant channels that at present, the development and production of large-scale aircraft in China have determined the method of project development and the supporting unit. Among them, China National Aviation Industry Corporation No. 1 (hereinafter referred to as China National Airlines) and a newly formed large passenger aircraft company will undertake the major development tasks.
Many equipment manufacturers have shown great interest in participating in large aircraft projects. However, from the voice of the company, there are not many channels for participation. Taking the machine tool as an example, even if it is a product of a domestic top technology machine tool manufacturer, it seems very difficult to participate in a large aircraft project. Both sides obviously lack an effective cooperation platform.
Large aircraft project to determine the division of labor
According to informed sources, at present, China has clearly defined the division of labor for large-scale aircraft projects. The specific project development will take the separation of large transport aircraft and large passenger aircraft, and rely on the existing aviation industrial enterprises and the formation of new aviation industrial enterprises.
Among them, the large transport aircraft is under the responsibility of the First Aircraft Design and Research Institute under the China National Aviation Corporation and Xi'an Aircraft Industry Group Co., Ltd. is the main production unit.
In addition, China will set up a new large-scale passenger aircraft joint-stock company in Shanghai, and operate in accordance with the three integrated corporate models of research and development, assembly and sales. Shanghai, as a headquarters for R&D, assembly and operation, manufactures can be subcontracted to other aviation industry companies in Sichuan, Shaanxi, and Shenyang.
China's large aircraft project has been fully demonstrated in the early stages and is now listed in the national development plan. According to the Outline of the National Medium- and Long-Term Scientific and Technological Development Plan (2006-2020) released by the State Council, large-scale aircraft projects have been identified as one of the 16 major scientific and technological projects that will strive to achieve breakthroughs in the next 15 years.
Informed sources pointed out that after determining the division of labor, the relevant state of the country will proceed with the development, design, and production of large-scale aircraft. "The government hopes to have the first prototype in about 10 years and begin industrialization after 2020."
Enterprises set about accumulating strength
There are indications that large-scale aircraft project related companies have already begun preparatory work.
According to report, China Guizhou Aviation Industry (Group) Co., Ltd. (hereinafter referred to as Guihang Group), one of the major companies under China Airlines, has just completed a purchase transaction. The purchaser is Guizhou Dongfang Machine Tool Factory. After the acquisition, Guihang Group will enjoy a 100% stake in the newly formed company and will invest no less than 100 million yuan in the next five years to carry out technological transformation to form a production scale with an expected production value of 1 billion yuan within 5 years.
Guihang Group is principally engaged in the manufacture of aircraft and auto parts. Although Guihang Group is not the main production unit for the development of this large aircraft, this does not mean that the company will not have the opportunity to participate in the future.
It is understood that during the acquisition of the Dongfang Machine Tool Plant by the Guihang Group, a related party from China Airlines has disclosed that the Guihang Group has been hoping to enter the field of equipment manufacturing and strengthen the group's machine tool manufacturing capabilities. Obviously, China Yihang intends to use this transaction to build strength for the upcoming large-scale aircraft development.
Drive the development of machine tools and other industries
Relevant experts believe that the acquisition of Dongfang Machine Tool Plant by Guihang Group is actually a signal that the driving role of China’s large aircraft project has already begun to appear.
However, some experts pointed out that the mere acquisition of a machine tool company could not meet all the types of machine tools needed for large aircraft manufacturing.
Du Renhuai, director of the Institute of Economics and Defence of the Nanjing Political Institute of the Chinese People's Liberation Army, pointed out that the development of large-scale aircraft is a large-scale system project involving many sub-systems, components and components. Different subsystems, components and components have different technical and process requirements for manufacturing equipment. China Yihang only acquired a Guizhou Dongfang Machine Tool Factory, which could not meet the needs of completing all equipment manufacturing work for large aircraft projects.
According to reports, the number of large aircraft parts is as many as millions, and the number of machine tools needed is even more varied. From ordinary machine tools to large precision high-end CNC machine tools, almost all machine types are included. Du Renhuai believes that this also reflects China’s strategy for developing large aircraft to promote the development of related industries.
According to Du Renhuai, the aviation industry is an integration of the national industrial base. The large-scale aircraft manufacturing industry has a strong industrial relationship, and its technology diffusion can be widely extended to the manufacturing industry. It can effectively promote the breakthrough of major key technologies such as CNC machine tools, electronics, materials, and engine manufacturing, and realize leapfrog development.
Lack of cooperation platform
According to the Secretary General of the Heavy Machine Tool Branch of the China Machine Tool Industry Association, most military systems currently use tendering to purchase equipment. However, he also pointed out that these tenders are only limited to the targeted bidding of a few equipment manufacturing companies. More equipment manufacturing companies still lack participation opportunities.
In this regard, Liang Xunji, honorary director of the China Machine Tool Industry Association, believes that in the past due to the planned economic system, the machine tool companies lacked initiative and thus lost the golden opportunity to establish close links with military industrial aircraft manufacturing companies.
Liang Xunyu said that this situation is improving. According to him, in order to strengthen the link between the military systems and the equipment manufacturing industry, the National Development and Reform Commission and the Commission of Science, Technology, and Industry for National Defense have organized a meeting of the military systems and equipment manufacturing industry each year. At this meeting, equipment manufacturers can understand what the military system needs. Equipment and other information.
According to relevant companies, the amount of procurement at the meeting was less on the one hand, and on the other hand, due to the high-end products, the production capacity of the company is still difficult to achieve.
Relevant sources pointed out that most of the machine tools and equipment currently used in aircraft manufacturing enterprises in China are imported. If the development of large aircraft, the domestic equipment manufacturing industry can not be assigned to "a glass of oysters", and China's original intention to start the development of large-scale aircraft project, I am afraid there is a divergence.
