DLR’s work on developing a distributed collaborative MDO environment is presented. A multi-level approach combining highly fidelity MDA for aerodynamics and structures with conceptual aircraft design methods is employed. Configuration-specific critical loads are used for sizing the structure. It is used to optimize the fuel burn of a long-range wide-body transonic transport aircraft configuration.
