AB - The application of Computational Fluid Dynamics (CFD) is often motivated by  the limitations of measurement techniques, economic limitations, and complex  model geometry or, as it is in this case, the unavailability of appropriate  test model geometry. CFD was used to assess and evaluate scenario that cannot  be investigated experimentally and was shown to be an efficient and  economical option to experimental setup. Because of that, there is a strong  need for a validation procedure and assessment of the data obtained by  numerical simulation. A combined experimental/numerical procedure is  described for determination and estimation of subsonic and supersonic  aerodynamic behavior of an AGARD-B model with a nonstandard nose  configuration. Conducted numerical aerodynamic calculations needed to be  satisfied via experimental tests so, the CFD code validation procedure  required experimental data that characterize the distributions of measured  aerodynamic forces and moments which act upon the test model. Validation of  the CFD was achieved by performing the calculation for the model with the  standard nose shape as well, and by comparing the results of the CFD  calculations with available experimental data for the model with the standard  nose configuration. Comparison demonstrated very good agreement between  numerically and experimentally obtained results. It was concluded that the  numerical prediction for the similar nonstandard model configuration could be  accepted as reliable and used to estimate the corrections needed when  interpreting the available data. The effects of the different nose shape were  found to be small and noticeable mainly in the pitching moment coefficient.  This work also demonstrates the application of CFD for the purpose of proving  a qualitative and quantitative prediction of the aerodynamics behavior.
