By design, a pumpkin balloon is intended to assume a cyclically symmetric "pumpkin-like" shape once it reaches float altitude and is fully inflated. Recent work by the authors showed that under certain circumstances, a strained, cyclically symmetric,

NASA's effort to develop a large payload, high altitude, long-duration balloon, the ultralong duration balloon, focuses on a pumpkin shape superpressure design. It has been observed that a pumpkin balloon may be unable to pressurize into the desired

Excess in skin material of a pneumatic envelope beyond what is required for minimum enclosure of a gas bubble is a necessary but by no means sufficient condition for the existence of multiple equilibrium configurations for that pneumatic envelope. Th

Large super-light structural systems that for functional reasons require large surfaces are composed at least in part of structural membranes. The underconstrained nature of such structural membranes poses analytical challenges, but also provides des

Effects of varying parameters in the design of super-pressure balloons of the “pumpkin” shape such as gore design, tendon stiffness, and structural lack-of-fit between tendons and gore seams are exhibited in analytical studies. The importance of

The computational challenge associated with pneumatic envelopes, such as balloons and parachutes, is due to the complication of their underconstrained and no-compression nature. Underconstrained behavior leads to large displacements without concomita

The wrinkling of membranes has been a subject of interset at least since the early part of this century. The standard model for analyzing membrane wrinkling is Tension Field theory, which provides a "coarse" model of the wrinkled membrane. The tradit
