The object-oriented MDAO framework for producing multi-fidelity unsteady aerodynamic loads and rapid Aeroelastic/Aeroservoelastic shape design of complex flight vehicles is a necessary tool throughout the aerospace industry. Such a tool is still non-existent, leading to a gap in practically every current flight vehicle MDAO capability. The MDAO framework will be developed in the Phase I can be such a commercialized product. If the proposed effort is a success, the developed MDAO framework can be directly employed for conceptual and/or preliminary design of aircraft considering multi-disciplines like flutter, static aerodynamic loads, stress, strain, buckling, etc.
NASA has recognized the benefit of utilizing commercial engineering applications within an MDAO environment. The proposed enhanced NASA MDAO framework will allow NASA to further leverage existing tools that can directly be applied for sizing and/or shape optimization of aircraft while considering multi-disciplinary analyses such as flutter, static aerodynamic loads, stress, strain, and buckling in conceptual and/or preliminary design phases. The proposed enhanced NASA MDAO framework with its robust automatic re-meshing tool providing fast and efficient mesh generation of complex internal structures, its hybrid optimization tool combining a non-gradient, and its gradient based method for faster solutions, and a fast transonic unsteady aerodynamics method for accurate aeroelastic analysis and shape sensitivity information will allow NASA to more rapidly modify existing and/or new aircraft structures while obtaining a higher level of fidelity in the optimized solutions.
