During the preliminary aircraft design phase various different configurations with a large number of unknown parameters are analyzed. New methods for preliminary aircraft design need to be implemented in order to meet the requirements of future aircraft. This paper presents an overview of how surrogate models are obtained with the help of the kriging method. Therefore, a short overview of the kriging method is given and a first surrogate model for the structural layout of a primary wing structure is introduced.The primary structure is modeled as a cantilever beam filled with ribs. The number of ribs and the shell thickness are varied within given boundary conditions. The presented surrogate model is based on the results from a finite element model of the given structure. Afterwards, an optimal solution according to the structural weight is found with the help of the surrogate model. These surrogate models will enhance the preliminary design process.
