This study aims to develop a computational fluid dynamics (CFD) analysis model to be used in the nose optimization at hypersonic speeds and to validate the model. While creating the analysis model, standard hyperballistic-1 (HB-1) geometry, whose tests were made in the wind tunnel, was used. Base equation used in the study is compressible real gas Navier-Stokes equations. Generated structured grids were analyzed in METACOMP CFD++. During the model validation, aerodynamic coefficients obtained from the CFD analysis were compared with the wind tunnel test results for HB-1. Comparing CFD results and wind tunnel data for axial force coefficient indicated that CFD analysis estimates this coefficient 5% lesser. Examining normal force coefficient and pitching moment coefficient showed that the results obtained from CFD analysis had a similar trend to the wind tunnel results.
