JAXA Research and Development Report: Research Reports on High Altitude Balloons
Development of a balloon to fly at higher altitudes is one of the most attractive challenges in scientific balloon technologies. The development of the high altitude balloon with a thin film has been engaged since 1991. After reaching the highest record setting balloon altitude of 53.0 km using the film with a thickness of 3.4 micrometers and a width of 160 cm in 2002, it was tried to make a thinner balloon film. In 2003, a forming die and an air-ring were developed and it was succeeded to form a film with a thickness of 3.0 micrometers and a width of 220 cm. Using this film, a balloon with a volume of 5,000 cu m was manufactured and it was succeeded to fly the balloon up to an altitude of 43.8 km. Then a good combination of resins to make a thinner and wider film was searched for and films with widths of 280 cm, and a thickness of 3.0 micrometers were obtained at first, and then 2.8 micrometers. In 2004, balloon experiments were performed making a 30,000 cu m balloon with the 3.0 micrometer film and a 5,000 cu m balloon with the 2.8 micrometer film. Both balloons were well manufactured and reached the highest altitudes of 50.7 km and 42.6 km, respectively.
