A low ballistic coefficient vehicle can drastically reduce peak aerodynamic heating during atmospheric entry. We are developing the new atmospheric entry system using an inflatable flexible aeroshell. A fight test of the system, which is aiming to verify the design method of the inflatable flexible aeroshell, is planned for late August, FY2008. The flight test is performed by stratospheric balloon-drop from altitude of about 30 km. In this paper, the system configuration and the operation sequence of this experiment system are overviewed.
