An object - oriented multi - disciplinary analysis and optimization ( MDAO ) tool has been developed at the NASA Dryden Flight Research Center to automate the design and analysis process and leverage existing commercial as well as in - house codes to enable true multidisciplinary optimization in the preliminary design stage of subsonic , transonic , supersonic and hypersonic aircraft . Once the structural analysis discipline is finalized and integrated completely into the MDAO process , other disciplines such as aerodynamics and flight controls will be integrated as well . Simple and efficient model tuning capabilities based on optimization problem are successfully integrated with the MDAO tool . More synchronized all phases of experimental testing ( ground and flight ) , analytical model updating , high - fidelity simulations for model validation , and integrated design may result in reduction of uncertainties in the aeroservoelastic model and increase the flight safety .
