“…The tendons were similar to the load tapes in zero-pressure balloon. 2,3) Each tendon was installed along the seam between adjacent gores and its length was intentionally shortened than length of the seam. In order to realize this, wrinkles were made along the edges of the gores.…”

“…The stress only depends on the local radius of the film r as in Eqs. (2) and (3). So the stress can be uncoupled from the radius of the balloon R. Hence the stress is not directly related to the size of the balloon in pumpkin design.…”

The pumpkin shape design is one of the most effective methods for super-pressure balloon design. In this paper, the method of designing a pumpkin super-pressure balloon is studied and equivalent strength concept is introduced in the design process. Fabrication method is also discussed. In order to verify the method, a 6 meters test balloon was fabricated and tested. The maximum differential pressure matched with the design value and the design method proved to be usable. Through the test, intuitive understanding of pumpkin super-pressure balloon was obtained and method of designing was verified.

“…With wider applications of high-altitude balloons as a cost-effective means in the Earth's atmosphere, there is growing interest in assessing balloon performance and failure mechanism. 1 Various experimental [2][3][4] and analytical 2,5,6 techniques have been developed to predict geometrical shape and stress state of high-altitude balloon. Most of experimental methods are still largely based on experience and empirical data for balloon analysis.…”

This article seeks to outline novel simplified model and analytical solution for predicting geometrical shape and film tension of high-altitude balloon. Sphero-conical and ellipsoid-conical models were proposed to depict geometrical configuration of high-altitude balloon subjected to a payload. By considering the effect of atmospheric factors and lifting gas temperature on geometrical shape of balloon, geometrical parameters of equilibrium shape were solved, based on minimum potential energy principle satisfying material constraint. New analytical solution was derived to allow balloon film tensions in meridional and circumferential directions. Finally, new model and its solution were used for predicting geometrical shape and film tension of natural-shape balloon on the ground and on float in stratosphere respectively, demonstrating the practical and effective use of the proposed model.
