The aerospace industry, as a cornerstone of modern high-tech manufacturing, encompasses civil aviation, defense, and space exploration, while representing a high degree of integration in materials science, precision machining, and intelligent manufacturing. The entire industry chain spans from upstream development and supply of high-performance materials, through midstream precision component manufacturing and modular assembly, to downstream final assembly, flight operations, and maintenance. Each segment imposes stringent requirements on safety, reliability, and performance. With the continuous expansion of the global aviation market and the rapid development of carbon-neutral initiatives, smart manufacturing, and digital technologies, the aerospace industry chain has become highly complex and interdependent.
