Abstract
A captive balloon system named InfoBalloon has been developed as a system for collecting and distributing disaster information. To support a disaster area, the captive balloon has to be stably moored. However, height, position and posture of the captive balloon are in danger of changing by wind in mooring. So it is necessary to evaluate behavior of the balloon in various wind conditions and methods of mooring to develop steadier InfoBalloon. We know the motions of the balloon are different depending on the conditions of the mooring point, so we evaluate the balloon motion of each mooring condition under changing wind direction and wind speed with the mooring simulator. Finally, we simulate rotation around the axis of symmetry of the balloon.
