PROBLEM TO BE SOLVED: To provide a captive balloon which has a low possibility of an increase in inclination of a balloon even if the balloon receives air current.SOLUTION: A captive balloon 1 has a baloon 10, plural mooring cables 30 to 33 each of which is connected to a surface of the baloon 10 at one end, and a cable length adjustment part 50. The cable length adjustment part 50 adjusts a length of any one of the plural mooring cables 30 to 33 according to wind velocity of air current received by the baloon 10. Further, the captive baloon 10 may include a membrane-like scoop 20 which is joined to the surface of the baloon 10 and is connected to a mooring cable of which a length is adjusted by the cable length adjustment part 50.
【課題】気球が気流を受けたときでも気球の傾きが増大するおそれが低い係留気球を提供する。【解決手段】本発明に係る係留気球1は、気球10と、それぞれの一端が気球10の表面に接続された複数の係留索30〜33と、索長調整部50とを有する。索長調整部50は、気球10が受ける気流の風速に応じて複数の係留索30〜33の何れかの長さを調整する。本発明に係る係留気球10は、気球10の表面に接合されると共に、索長調整部50が長さを調整する係留索に接続される膜状のスクープ20を更に有してもよい。【選択図】図1
