Recently, the national production line of large aircraft skin was officially completed in Xi 'an Aviation Base, which realized the low-cost production of large aircraft skin, which will effectively enhance the industrial competitiveness of the jurisdiction and help the commercial success of domestic large aircraft.

So what exactly is skin? According to reports, the skin is equivalent to the "skin" of the aircraft, and its main function is to protect the internal structure of the aircraft, maintain the shape of the aircraft, and make it have good aerodynamic characteristics. Because aircraft often face strong aerodynamic forces in flight, the strength, plasticity, corrosion resistance and technological level of skin materials are required. For a long time, the key equipment for skin manufacturing is only in the hands of a few developed countries, which restricts the development process of domestic large aircraft in China. The successful establishment of the national production line for large aircraft skin is undoubtedly of great significance to domestic large aircraft.

It is reported that after the national production line for large aircraft skin is fully put into production, it is estimated that it can produce more than 100 domestic large aircraft skin parts on the nose, front, middle and rear fuselage, door and movable wing surface every year, which will solve the capacity bottleneck and cost reduction needs of most domestic large aircraft customers and promote the high-quality development of the domestic large aircraft skin industry. In order to solve the problems of environmental pollution of skin milling, high equipment cost and low processing efficiency of mirror milling, Xi 'an Xinghang Airlines organized a professional team to carry out a large number of technical research and engineering tests, innovated and optimized the current skin processing technology, and made major technological breakthroughs. It has applied for 4 invention patents and 6 utility model patents, ensuring the smooth establishment of a low-cost large aircraft skin production line suitable for mass production.
