The structural layout design of wing must satisfy various requirements and consider manifold qualitative and quantitative factors, where expert's experience, judgment, and heuristic reasoning play important roles. Hence those algorithm-driven methods and tools can not solve the layout design problem effectevely. In this paper the implementation of knowledge-driven technologies for wing structural layout design was studied. The different kinds of knowledge, the solving strategy, as well as the knlwledge-driven blackboard architecture applied in wing structural layout design were discussed, and were incorporated into an uniform framework for knowledge management and solving system. A prototype of intelligent design system was developed for wing structure layant and was applied to the wing strutural layout of a fighter. The prototype produced a reasonably preliminary structural layout scheme according to the design requirements given by user. The study shows that developing knowledge-driven design tools should be a feasible approach to the wing structural layout problem.
