This paper describes an approach to optimization of composite aircraft wing structure basing on multi-criterion method. Two types of composite wing structures such as two-spar and three-spar ones were considered. The optimal layout of a wing frame was determined by Pareto optimization method basing on three criteria: minimal wing deflection, maximal safety factor and minimal weight. Positions of internal wing frame parts (spars and ribs) were considered as optimization parameters. As a result, an optimal design of a composite spar-type wing was proposed.
