Within the content of this research, it is aimed to optimize rib spacing of a generic UAV wing to maximize its flutter speed. Therefore, magnitude of the wing’s torsional frequency value and ratio of the torsional frequency to the first body bending frequency value are aimed to be maximized. Optimization process is accomplished by modeFRONTIER optimization software. During the process Multi Objective Genetic Algorithm-2 solver is used. Finally, the optimum rib spacing value is determined for the wing structure.
