Review of correlation analysis of aerodynamic data between flight and ground prediction for hypersonic vehicle

The current status and the trend of correlation analysis of aerodynamic data between flight and ground prediction for hypersonic vehicles are reviewed and summarized, including the development of aerodynamics ground tests investigation, numerical computation investigation and the test data extrapolation methods investigation. Relating to the ground wind tunnel tests investigation, the test capabilities and the deficiencies closely related to the design of hypersonic vehicles both domestical and abroad are focused on. About the numerical computation investigation, the comprehensive capabilities of typical domestic and foreign CFD softwares, together with their expansibility to satisfy the requirements of hypersonic vehicle development are reviewed. For the aerodynamic data extrapolation methods, correlation methodology employed in early design process of USA space shuttle, X-43A and other test vehicles are presented. Finally, some important problems which needs to be dealed with carefully and rationally during the study of correlation analysis of aerodynamic data between flight and ground prediction for hypersonic vehicles are further pointed out based on above analysis.
