DETERMINATION OF THE SHAPE OF A FREE BALLOON. BALLOONS WITH ZERO SUPERPRESSURE AND ZERO CIRCUMFERENTIAL STRESS

Abstract

This report, the second of a series, presents the numerical methods used and the results of the computation of the shapes of axi-symmetric free balloons. Flat-top balloons, re-entrant top balloons and double balloons, all with zero circumferential stress and zero superpressure at the bottom apex, are considered. Meridional film loads are presented. An extensive Sigma Table suitable for balloon design is included for the flat-top balloon with sigma = 0(0.05) 1.0.
