Study of Stratospheric Powered Balloon System

研究的最终目标是在平流层上层实现一种飞行方向可控的漂浮飞行器。动力气球的可能性结合了一种超压气球，这种气球的空气阻力比传统的科学气球小，带有机载推力装置和姿态改变机构。制作了田原式气球的比例模型，并搭建了室内实验系统。测试了从充气到飞行终止的过程，增加了动力气球系统实现的可能性。

The final goal of the study is to realize a floating vehicle in the upper-stratosphere of which traveling direction can be controllable. The possibility of a powered balloon combining a tawara type of super-pressure balloon of which air-drag is smaller than that of a conventional scientific balloon with on-board thrust units and an attitude changing mechanism. A scale model of tawara type of balloon was manufactured and an in-door experimental system was constructed. It was tested for the process from the inflation through the flight termination, which contributed to increase the possibility of realization for the powered balloon system.
