In this article, a design methodology for complex composite aircraft structures is
presented. The developed approach combines a multi-objective optimization method and a
parameterized simulation model using a design concept database. Due to the combination of
discrete and continuous design variables describing the structures, evolutionary algorithms are
used within the presented optimization approach. The approach requires an evaluation of the
design alternatives that is performed by parameterized simulation models. The variability of
these models is achieved using a design concept database that contains different layouts for
each implemented structural part. Due to the complexity of the generated aircraft structures,
the finite element method is applied for the calculation of the structural behaviour. The applicability
of the developed design approach will be demonstrated by optimizing two composite
aircraft fuselage examples. The obtained results show that the developed methodology is useful
and reliable for designing complex aircraft structures.
