| Outline of Final Research Achievements |
In this study, we investigated the aerodynamic characteristics of the reentry vehicle with the inflatable structure using the lift force by using CFD analyses and wind tunnel experiments. The numerical and experimental results suggest that in the case of the torus shape if the dimension of the inflatable structure is designed so that the wake flow of the reentry vehicle is located inside the torus to avoid the shock-shock interactions the attitude of the inflatable structure connected to the reentry vehicle by the cables is stable in the hypersonic flow regime. Additionally, in the case of the supersonic, transonic, and subsonic flow regime, the attitude was not so sensitive to the dimension of the inflatable structure.
