Our group has researched and developed a capsule-type vehicle with a flare-type membrane aeroshell supported by an inflatable torus frame. The characteristics of inflatable aeroshell are not well understood particularly under the environment where the ambient pressure varies significantly. Therefore, the flight experiment using a scientific balloon is conducted in order to acquire basic techniques and knowledge for constructing the system of a vehicle with the inflatable membrane aeroshell. The diameter, mass, and ballistic coefficient of the experimental vehicle are 1.264 m, 3.375 kg, and 2.69 kg/m2, respectively and its aeroshell consists of a torus which can be inflated by gas pressure and a thin membrane flare made of nylon. The inflatable aeroshell was deployed and the experimental vehicle was separated from the balloon at an altitude of 25 km. After the separation, the vehicle flied 30 minutes without problems. All the sequences are properly executed, and following results were achieved. 1) Remote deployment system of the inflatable aeroshell by sending a command from a ground station was successfully conducted. 2) Data of aerodynamic characteristics, for example drag coefficient, were obtained after analyzing a flight data. 3) As for a structural strength of inflatable aeroshell, valuable data was obtained which can be compared with preliminary structural test using low-speed wind tunnel.","subitem_description_type":"Other"}]},"item_3_description_18":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"著者人数:
