Determination of the Shape of a Free Balloon. Balloons with Superpressure, Subpressure and Circumferential Stress: And Capped Balloons

摘要

Results of the computation of the shape of an axisymmetric free balloon are presented. Flat-top balloons with superpressure, with subpressure, and balloons with circumferential stress are considered. Circumferential stress is both held constant and varied as a function of meridional stress. Certain limitations on circumferential stress are noted. Shapes, meridional stresses, and circumferential stresses are presented. In addition, similar results are presented for capped balloons with a doubleweight cap covering the upper half of the balloon.
