Evolution and Future Trends of Aircraft Manufacturing: Integration of Materials, Structures, and Intelligent Processes

Abstract

This paper systematically reviews the development course of aircraft manufacturing, comprehensively covering four core dimensions: material selection, component design, manufacturing processes, and future trends. In terms of materials, to achieve a balance between lightweighting, strength, and corrosion resistance, the material system has gradually evolved to composites and titanium alloys. These materials not only effectively reduce the weight of aircraft but also significantly improve fuel efficiency while extending the service life of key structures such as fuselages and wings. In terms of component design, the industry has shifted from a traditional experiencedependent model to digital modeling and simulation technologies. With the help of precise digital tools, aerodynamic optimization is achieved, which not only reduces the weight of components but also significantly enhances the reliability of core structures like wings and fuselages, ensuring flight safety. In manufacturing processes, the industry has advanced from traditional processing modes to automated production and additive manufacturing technologies, and continues to move toward intelligent production, significantly improving manufacturing precision and efficiency. Faced with the increasing complexity of aircraft structures, process control and full-life-cycle management have become more crucial. Assisted by technologies such as real-time sensor monitoring and blockchain traceability, they effectively ensure manufacturing quality and operational safety. The combination of non-destructive testing technology and artificial intelligence further improves the accuracy and efficiency of defect identification. Although the industry still faces challenges such as high costs and increasing environmental pressures, the core of future development lies in the in-depth integration of materials, structures, and process technologies, promoting the coordinated development of intelligent manufacturing and green aviation, and ultimately achieving the goals of high efficiency, precision, and sustainability in aircraft manufacturing.
