Original Abstract

The article presents the topometry optimization of the critical semi-shell wing structure of the aircraft in the Commuter category of the CS-23 regulation standard (EASA 2012). Modern finite element (FE) optimization methods are used. The main outcome is that the milled integral lower wing panel allows significant weight savings due to an optimization of the thickness of each skin segment. The FE model validation with the analytical software and the selection of structural constraints and requirements for the optimization are described in this article. Also, a final stress analysis and a complex load capacity analysis validate required properties of designed structural modifications with an optimal stress distribution. Additionally the analysis of weight savings and elongation of the fatigue durability according to the Damage tolerance methodology was done.
