Optimum Design of Wing Structures With Multiple Frequency Constraints
Keyword(s):
Abstract In this paper, design optimization of aircraft wing structures with multiple frequency constraints is considered. An optimality criterion algorithm along with a scaling procedure has been used. Large scale structural design problems were considered for demonstrating the reliability and efficiency of the algorithm. A simplified fighter wing, an intermediate complexity wing, and a large wing typical of a transport aircraft were considered as design examples. Design histories and the first few frequencies at the initial and final conditions are presented.
