Abstract:
In this paper, design optimization of aircraft wing structures with multiple frequency constraints was considered. An optimality criterion algorithm along with a scaling procedure was used. Large-scale structural design problems were considered for demonstrating the reliability and efficiency of the algorithm. A simplified fighter wing, and an intermediate-complex wing were considered as design examples. Design histories and the first few frequencies at the initial and final conditions are presented.
