Outline of Final Research Achievements |
The purpose of this research was to develop a balloon experiment system which keeps flying for several weeks while moving up and down the tropopuase at sunrise and sunset. First, we quantitatively showed that the system can be realized by a tandem balloon system connecting a small zero-pressure balloon with a volume of 100 cubic meters and a super-pressure balloon with a volume of 10 cubic meters. Then, we developed the most important element, the super-pressure balloon, and also the satellite communication system. Finally, we successfully developed a 10 cubic meters super-pressure balloon with pressure resistance performance of 10,000 Pa, a very light weight of 3 kg and almost no gas leakage. We also established a compact communication system using Iridium satellites.
