Abstract
High-altitude balloons for scientific observations are required to fly for long-duration to obtain sufficient amount of data. The long-duration flight can be achieved with a super-pressure balloon. The super-pressure balloon increases the pressure tightness by decreasing the local curvature radius of the balloon film usually with many ropes between the poles of the balloon. However the increase in the number of the ropes also increases the fabrication cost of the balloon. Therefore, instead of the many ropes, we proposed to cover a balloon with a diamond-shaped net. The new super-pressure balloon has been developed since 2010 through ground inflation tests, numerical simulations, and flight demonstrations, gradually enlarging the size of the balloon. Our goal is to fly a payload of 900 kg to higher than 37 km altitude for several months with a 300,000 m3 balloon. In this paper, we will introduce the development of the new super-pressure balloon.
