Study on Correlation of Aerodynamic Heating Data of a Combination Model

Abstract

To study the correlation of aerodynamic heating of hypersonic vehicle, surface heat flux of different scale models in various flow conditions are obtained by means of wind tunnel, numerical simulation and engineering calculation. The correlation of aerodynamic heating of different scale models in various flow conditions has been studied using the modified viscous interaction parameter and Stanton number. The results showed that: Stanton number of different scale models in various flow conditions could be well correlated with the modified viscous interaction parameter. This correlative method provides a way to predict the surface heat flux in flight conditions.
