Multidisciplinary Optimization of Aircraft Structures with Respect to Static and Dynamic Aeroelastic Requirements

Autor(en): Ö. Petersson, F. Daoud
Zusammenfassung: The technical challenges of aircraft design are set to remain at least as difficult in coming years or may become even greater in future. Performance requirements are likely to continue to increase while there is a continuing desire, even for military applications, for a reduced energy footprint. At the same time, particularly in military aircraft design, development times and budgets are decreasing. This calls for more efficient design methods capable of delivering feasible designs fulfilling all design driving requirements more quickly than traditional methods. The latter are based on manually iterating between load case determination at different flight conditions and sizing of the structure to fulfil all necessary design criteria. The new approach at Cassidian has been to take advantage of Multidisciplinary Design Optimization in conceptual and preliminary design phases, integrating the loads calculation discipline for static and dynamic aerodynamic loads into the optimisation process, automatically adjusting the applied loads to the aircraft to modifications in the structural properties.
