JAXA Research and Development Report: Research Reports on High Altitude Balloons
Launching a large balloon at a limited launching field is a long standing subject in Japan. The volume of the largest balloon ever launched successfully was 200,000 cubic meters. This type of balloon was firstly launched in 1973. A larger balloon with a volume of 500,000 cubic meters was tried to launch in 1980; however it did not succeed because of burst during the ascending phase. For launching a large balloon with a total lift more than 1 ton, the static launching method, which has been used for more than 20 years, has several weak points that may result in failure. A semi-dynamic launching method was developed using a new launcher, which is fixed on the ground and has a freedom of rotation around the vertical axis and an elevation system up to 5 m, as well as a leap-up spooler system for holding a balloon bubble, in 1999. Several balloons have been launched using the method. In 2003, a balloon with a volume of 500,000 cubic meters, which was made of polyethylene films of 20 micrometers in thickness, was successfully launched with the semi-dynamic launching method. It is the largest balloon ever launched in Japan.
