    Abstract

    Weight targets and shortened time scales in the civil aircraft industries calls for an integration of advanced computer aided optimization methods into the overall component design process. Finite element based topology, sizing and shape optimization tools are typically used to obtain a first view on an optimal configuration for the structure-an initial design with optimal load paths. Next, the suggested configuration is interpreted to form an engineering design. The success of the above optimization scheme depends upon the proper interpretation of the results from these optimization methods. This paper deals with the topology and size optimization of stubwing structure of a typical light transport aircraft. By using these techniques a weight reduction of 15% was obtained. This methodology can be adapted to different Aerospace components.
