Original abstract

The detailed topometry optimization of the critical part of an aircraft wing is presented in this article. The integral lower wing structural panel of aircraft in the Commuter category of the CS-23 regulation standard is selected for optimization. The first case demonstrates significant weight savings using modern Finite Element (FE) optimization methods for determined structural constraints. A practical aircraft operation and additional regulation requirements affect optimization constraints in the second case. This detailed optimization also consists of FE model validation, stress analyses and complex load capacity analyses, which are necessary for designed structural modifications with an optimal stress distribution.
