Abstract: Knowledge management platform for structural design of projectiles and rockets was studied and developed aiming at present condition of structural design of China Academy of Launch Vehicle Technology (CALT). Three key technologies of platform were introduced, such as mining technology of explicit knowledge, mining technology of implicit knowledge, and retrieval technology of design knowledge. System architecture of platform was put forward. And functional model of platform was expatiated. The effect of platform in CALT is remarkable. It shows that the platform is feasible and reconfigurable.

Key words: projectiles and rockets, structural design, knowledge management, explicit knowledge, implicit knowledge
