Biologically Inspired Folding Structure for Space Habitats

This report describes a folding structure that creates the maximum volume of a sphere from a cylinder.

A mechanism for folding the module’s support structure covered with a flexible shell (like the one developed for Transhab) allows the module to be folded for its transfer to orbit aboard the space shuttle. In space it is inflated to be brought into its spherical shape. The support structure which stabilizes the inflated module, carries elements such as life support equipment and stowage racks. An outfitting for this kind of modules is proposed.

The sphere is compared to its historical backround and the folding structure is shown in comparison with architectural and biological principles.
