JAXA Research and Development Report: Research Reports on High Altitude Balloons
A zero-pressure balloon used for scientific observation in the stratosphere has an unmanageable limitation that its floating altitude decreases during a nighttime because of temperature drop of the lifting gas after a sunset. Once a practical size of super-pressure balloon without venting ducts was developed, its lifetime can extend very long because the volume may not change. We proposed a new super-pressure balloon design, which is constructed by a concept of "lobed-pumpkin with lobed-cylinder" and can adapt a single design for balloons of a wide range of volumes. The advantage and formulation of this new design are presented in this paper. The results of a flight test as well as indoor inflation experiments are also considered to study the validity of the design and fabrication method. This new shape could realize a powered balloon system in the future because of its reduced drag shape.
