The generation of a tabular aerodynamic model for design-related flight dynamics studies, based on simulation generated data, is considered. The framework described accommodates two design scenarios. The first emphasizes the representation of the aerodynamic nonlinearities and is based on sampling. The second assumes an incremental change from an initial geometry, for which a high-fidelity model from the first scenario is available. In this case, data fusion is used to update the model. In both cases, Kriging is used to interpolate the samples computed using simulation. A commercial jet test case, using DATCOM as a source of data, is computed to illustrate the sampling and fusion. Future application using computational fluid dynamics as the source of data is considered.
