AN INVESTIGATION OF HIGH-ALTITUDE BALLOONS OF SHAPES WHICH ARE NOT ROTATIONALLY SYMMETRIC.
Abstract
An attempt was made to explain the occurrences of nonsymmetrical balloon shapes, using the assumption that the balloon material is in a uniaxial state of stress in the direction of the meridians. This attempt was unsuccessful. It was found that this assumption does not permit the existence of non-symmetric balloon shapes. There is no question that non-symmetrical shapes occur at inflation, but the occurrence at partial inflation is uncertain. In any case, hoop and shear stresses occur at launching, and under wind load, such that it seems logical, to provide for hoop and shear stresses in the future development of reinforced Mylar or other new fabrics.
