The activities encompassed in this proposal, aimed to provide a trade-off study between a reference wing stub box design and alternative advanced designs of the same structure incorporating new technologies. This exploited a methodological approach, which allowed the simulation problem to be solved efficiently, by tackling all possible issues related to management of the geometries, definition of a high-quality mesh, application of specific composite material behaviour laws, up to loading, solution and post-processing.

The advanced character of the forecast approach is linked to the following aspects:

• the complete modelling process will be integrated into a parametrised global process flow that, under the control of the Multi-Objective Optimisation algorithms implemented within the modeFRONTIER tool, will allow a quick and complete exploration of the influence of the parameters that can influence the system performances;
• the complete set of analysed models will be explored (again using the modeFRONTIER tool) to rank them with respect to their key performances and to select the optimal candidate(s) considering the multiple selected objectives, by exploiting the mostly advanced Multi Criteria Decision methods.
