Summary

The report documents the development of new computer programs for the automated minimum weight design of aerospace structures. Two programs are discussed in detail, an intermediate capacity linear merit function program, and a large scale nonlinear program. The intermediate capacity program can be used for the optimization of major structural components of up to approximately 170 degrees of freedom with fixed configuration. The large scale program is capable of handling structures with up to 450 degrees of freedom and includes geometric variables. Detailed descriptions of the preparation of input data are included. Examples are given of the application of the program to a wide variety of structures including major airframe components, indicating the weight savings possible through application of the optimization techniques.
