Abstract:

This report documents the development of a method of obtaining minimum-weight designs of aircraft structural components under imposed flutter requirements. The end product of this development is a system of pilot computer programs that can accurately determine the flutter speed of an aerodynamic lifting-surface structure and then find a minimum-weight design at this same flutter speed. The programs have current dimensional capability for only moderate-size discrete structural models, with limited numbers of design variables, but demonstrate a technique that can be adapted to large-scale systems. Details of the theoretical development and of the computerized system are included along with applications to the optimization of several example structures. Author
