Abstract

PURPOSE: To make the floating altitude adjustable without any complicated mechanism by allowing a part of a convering material forming a steamline type balloon to be housed inside the balloon.
CONSTITUTION: Beams 11, 14 and 15 made of round bar easy to bend though unable to stretch lengthwise is arranged in a covering material 13 forming a steamline balloon. To the beams, mounted are a crossbeam 16 having circular notches at the center at a proper space and wounding rollers 1 and drive rollers 18 are arranged piercing the notches. With such an arrangement, with the positive or inverse rotation of the drive roller 18, a part of the covering material is wound or unwound by the roller 17 whereby the capacity of the steamline type balloon is changed without deforming the shape. In this manner, the floating altitude of the balloon can be adjusted without throwing any balast away or releasing any floating gas.
