Abstract

Optimal design of complex engineering systems, such as aircraft composite structures, can often be accomplished only by applying decomposition techniques. In this paper, the optimal design of a composite wing-box is addressed by using a two-level scheme based on the Genetic Algorithm meta-heuristic. The two-level optimization strategy was evaluated for variations both in the angular step of the composite layers and in the strength of material.
