| Outline of Final Research Achievements |
Scientific balloons have weak points that the balloons can not fly long duration flights. To solve the problem, we have been developing a super-pressure balloon by covering its film with a net. We have developed element technologies for large balloons and confirmed balloon design through series of inflation tests of small balloons and numerical simulations. Finally, we have succeeded in developing a super-pressure balloon with a volume of 2,000 m3, a weight of 54 kg, and capability to withstand differential pressure of 1,000 Pa. This balloon can fly a long duration flight at an altitude of 22 km with a payload of 40 kg to perform, for example, meteorological observations. This is the first super-pressure balloon in Japan with a capability to perform scientific experiments.
