In structural design of aircraft optimization methods are applied to analyze complex structures with high accuracy. During the last decade considerable effort has been spent to develop modern multidisciplinary structural optimization procedures, using efficient mathematical optimization algorithms which satisfy all requirements simultaneously and to find an optimum of the design variables. An overview of the Multidisciplinary Optimization (MDO) techniques shows how these methods primarily support the preliminary - and detailed design phase. The different optimization methods are discussed and the architecture of the used program LAGRANGE is described. This program is designed as open as possible to incorporate all kinds of disciplines for actual and further projects. Features like shape and topology optimization are being added to the overall program to improve the quality of the products and reduce development phase of advanced systems. Different examples are discussed to show the applicability and to demonstrate the benefits of the exciting structural optimization software in design phases.
