FREE BALLOONS WITH OFF-DESIGN PAYLOADS,

Abstract

The membrane equations for an axi-symmetric balloon and the equation of equilibrium are modified for application at conditions other than the design payload and design altitude. Examples are presented which show the change of shape, stresses, volume and float altitude resulting from payloads different than the design value. It is shown that, for payloads greater than the design value, local radius decreases everywhere so that no fullness is required to maintain zero circumferential stress. For payloads less than the design value, circumferential stresses are developed in the fully tailored portions. (Author)
