As the most representative additive manufacturing method in the field of aviation equipment at present, the laser additive manufacturing supports the structure design innovation, rapid development and verification. Among them, selective laser melting is mainly used for precision near net shape manufacturing of complex precise functional structures, and laser direct metal deposition is mainly used for manufacturing large and complex load-bearing structures. In order to support the strategic layout of the development of additive manufacturing technology in the aviation field, this paper sorts the current situation and development trend of laser additive manufacturing, and points out that the focus of additive manufacturing development is bound to turn to the metallurgical quality, mechanical properties and their stability control of products. The research and development of intelligent functions such as online monitoring, parameter self-tuning control of additive manufacturing equipment are becoming a research hotspot. Either the research on mechanical behavior of additive parts based on damage failure analysis and life prediction or the performance evaluation and verification technology based on components and characteristic structures have begun to attract the attention of engineering application departments. Based on the analysis of the technology development trend, the development goal of laser additive manufacturing technology in the aviation field in 2035 and the corresponding policy and environmental support and guarantee needs are proposed, and the technical development roadmap in 2035 is put forward. In 2025-2035, the control technology of microstructure,property and deformation for additive manufacturing of ordinary metal, intermetallic compound, Nb-Si and ceramic based material is to be made a comprehensive breakthrough, the performance verification is to be basically completed, the functional assessment has been partially completed, and some products are to be entered mass production. Important load-bearing structures of aircraft and rotating parts of aeroengine made by additive manufacturing are to be widely used. |
