ABSTRACT:
A high-altitude balloon having prestrained gores made from an asymmetrical gore pattern. The invention includes the balloon, the method of assembling the balloon, and a table specially designed to implement the method. The method can be used to assemble balloons of varying shapes and sizes, within a determinable range of ratios of gore width to gore length. The method involves cutting and sealing edges of a pair of flexible plastic sheets along a straight edge of a table, then inverting the seam so formed until it is aligned with a curved index line on the surface of the table. The curved index line is longer than the seam created along the straight edge so stretching is required during inverting. Successsively cutting, joining and inverting pairs of sheets in this manner produces a balloon with a plurality of symmetrical gores that give the balloon a predetermined shape when inflated.
