A multi-level optimisation approach is applied to the design of composite aircraft fuselage barrel and panels. Surrogate models are applied to enhance the computational efficiency of the panel sizing evaluations in the design optimisation iteration. Results of the achieved designs and associated computational costs will be reported.
