In recent years, Changsha has established strategic partnerships with companies such as AVIC and China Commercial Aircraft Corporation. Major aircraft landing gear, wheel brake systems, and engine nacelles have all settled in Changsha.

Recently, the reporter saw in the Changsha Aviation Industrial Park in the Wangcheng Economic Development Zone that the two newly completed 60,000 square meters integrated processing plants resemble the wings of the aircraft. They are mainly used to produce aircraft landing gear and engine nacelles. The Changsha Aviation Industrial Park, with a total investment of 3.5 billion yuan, is mainly used to produce parts such as piston rods, anti-torsion arms and brake systems for aircraft landing gear, as well as international subcontracting production and processing of civil aviation products. The relevant person in charge of AVIC Landing Gear Co., Ltd. introduced that after the third phase of the project is fully put into operation, the base will directly target the national “big aircraft” project and become the supplier of the world's third-class landing gear in the future.

As early as 2012, Boyun New Materials established a joint venture with Honeywell in the United States to jointly undertake the C919 large passenger aircraft wheel, tire and brake system manufacturing project. The reporter learned that the pre-design of the C919 wheel brake system has been basically completed. The plant construction and process transfer work is underway. The trial production will be realized within the year and mass production will be realized next year. At the same time, it will apply for international standards and strive to enter the international market as soon as possible.

Aerospace is characterized by intensive technology, capital intensiveness, and high added value, which can simultaneously drive the development of high-tech industries such as modern manufacturing, electronic information, and automatic control. With the construction of Changsha, Zhuzhou and Xiangtan National Aviation High-tech Industrial Base and Changsha Aviation Industrial Park, the world's top 500 companies such as Honeywell and Liebherr in Germany have settled in Changsha. Changsha's aerospace industry has already participated in the international industrial division of labor. Ability.

The rise of high-performance materials manufacturing base

In January of this year, Hunan Province issued the “General Aviation Industry Development Plan of Hunan Province”, which will focus on the development of high-strength lightweight alloy materials, ablative carbon/carbon composite materials and aerospace materials for aerospace key structural components such as aluminum alloys and titanium alloys. Magnetic materials and super-hard materials, etc., strive to form an industrial scale with an annual sales income of over 20 billion yuan.

As a representative of China's high-end magnetics, Hunan Aerospace Magnetoelectric Co., Ltd. owns the only magnetic materials research institute of China Aerospace. The company's aerospace high-performance magnetic materials industrial park in the Wangcheng Economic Development Zone has been completed and will be moved into the new plant this month. The project has a total investment of 560 million yuan and a construction area of ​​70,000 square meters. Three high-performance permanent magnet ferrite production lines and one high-performance sintered NdFeB production line have been built. It is expected that high-performance ferrite permanent magnets will be formed by 2015. The magnetic volume of 20,000 tons and the ferrite permanent magnet ring magnetic 10,000 tons will form a sales scale of more than 1.5 billion yuan after the completion of production. By 2020, the output value will reach 2 billion yuan.

The Botai Aviation Materials Project site in Changsha High-tech Zone is under construction. The first phase of the plant has been basically completed at the end of last month. It is currently entering the trial production phase, and the second phase of the plant is also under construction. The project covers an area of ​​180 mu and has a total investment of over 500 million yuan. It will be built by the AVIC Beijing Aeronautical Materials Research Institute and will be built into a national high-performance aerospace material manufacturing base with an annual output of 17,900 tons of high-performance aerospace materials. With an output value of more than 2.4 billion yuan, its high-performance aluminum alloy pipe rod profiles have independent intellectual property rights and are widely used in aerospace, ship and other fields, breaking the monopoly position of foreign products in the industry.
