Abstract
One of the earliest applications of optimization to engineering design was that of designing structures for minimum weight. While widely applied, it is particularly useful for aerospace structures, where the penalty for dragging unneeded weight into the sky is often quite high but where even minor structural failures can be catastrophic. The methods used for structural optimization are not unique, but the problem formulations are. A particular application of aerospace structural optimization is that of designing aeroelastically scaled wind tunnel models. These represent a type of inverse problem in which the mass and stiffness properties are known beforehand and the designer must create a structure that both fits inside the required aerodynamic envelope and has those properties.
