The design for typical structural parts of aircraft directly affects the aircraft’s quality and maintenance cost. This paper analyzes the necessity of intelligent optimal design for typical aircraft structural parts and studies its current situation and development trend at home and abroad. In this paper, a new intelligent optimization design technology for typical aircraft structural parts is proposed. Based on its design framework, the technical system, the design method integrating knowledge, and the verification ideas based on the Internet architecture are described in detail. Finally, the next step is envisaged. Engineering implementation shows that the proposed intelligent optimization design technology greatly improves the quality of aircraft and reduces the cost of design and maintenance.
