• 一般注記: A flight test of a super-pressure balloon with a volume of 2,000 m3 covered by a net was conducted as a B20-03 experiment. This was the first time that this type of super-pressure balloon flew without being suspended from another balloon. The balloon was launched using the semi-dynamic launching method as usual, however, the ascending speed of the balloon was lower than expected immediately after the launching and was slowing down. Ballast were dropped to maintain the ascending speed of 5 m/s. After the balloon reached the safe area, the tear mechanism was functioned to break the balloon. The problem of the low ascending speed was investigated by analyzing the obtained data and recovered balloon. It was confirmed that the gas was leaked from the analysis of the balloon images obtained by the on-board camera, and was confirmed that the leak started after the spooler release from the constant upward tension of the spooler measured by the load cell just before the spooler release and the slow initial ascending speed of the balloon compared with the theoretical estimation. The examination of the recovered balloon revealed that the balloon was damaged by hundreds of unique slit holes with creep bands around the edges. After investigating the conditions for making similar holes, it is probable that it was caused by impact destruction that the net hit the balloon envelope with a speed of 10 m/s or more at the time of spooler release. To solve this problem, two possible solutions are being researched: using a multilayer film for the balloon enveloped to avoid leaks even damaged and developing a new launching method without moving balloons quickly.; 形態: カラー図版あり; Physical characteristics: Original contains color illustrations; 資料番号: AA2130029001; レポート番号: JAXA-RR-21-003
