AbstractA super-pressure balloon, which can reach the stratosphere with a heavy payload and continue to fly without ballasting, is quite useful for a long duration circum-polar flight. It has been quite difficult to develop such kind of balloons because of large pressure applied to the balloon film. The authors have investigated a new balloon design concept that reduces the film tension dramatically so as to enable the balloon to withstand high pressure. Experimental research has been proceeding to use the different size model balloons step by step. This report describes the current status of the research and development of the super-pressure balloon. The first successful flight-test in the world for the balloon using this concept is also reported in this paper.
重い積載物を積んで成層圏まで達し、バラストを積むことなく長時間飛び続ける高耐圧気球は、長期にわたる極域周回飛行に非常に便利である。このような気球を開発することは、気球の膜に非常に大きな圧力がかかるため極めて困難である。著者らは気球が高圧に耐え得るように、膜に加わる張力を大きく減らす新しい設計概念を研究した。実験的研究は、異なる大きさのモデル気球の使用に着実に取り掛っている。この報告では高耐圧気球の研究開発について述べた。このような設計概念に基づく気球を用いて世界で初めて成功した試験飛行についても本稿で報告した。
