Knowledge-driver design of wing structural layout

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.
