In late design stages the detailed design is addressed up to the arrangement of composite plies and advanced numerical tools are used for virtual testing. In preliminary design stages the distribution of thicknesses is considered with engineer justification stress tools. In early design stages the design is concentrated on architecture, choice of materials, choice of profiles and requires a fast sizing procedure and less accuracy on detailed stress calculations. Each design stage requires a suited methodology and tool. For the rapid sizing needed at conceptual design stage, a prototype tool called RHAPSODY has recently been developed by AIRBUS with SAMTECH for such sizing studies. The approach was to degrade in an acceptable extent the preliminary sizing in order to speed-up the reactivity of the tool and focus on
                  higher level parametric studies. Optimisation problem reductions and simplifications were made. Surrogate models from polynomial to Artificial Neural Networks were used. Library of profiles and materials were built and exploited. The optimisation process usually restricted to covers was extended to internal components with the target to address whole aircraft structure optimisation. This sizing tool, when fully mature and coupled with a full CAD-CAE associative link enabling architecture parameterisation should help AIRBUS to design the best airframe concepts in the quickest lead times.}
