Description

Origami-based and origami-inspired designs provide paths to achieve highly compact, stowable designs, that can be deployed to large surface areas. This potential is highly beneficial to the area of space antennas and LIDAR as these require compact stowing in a launch payload, but large apertures when deployed in space. Because the engineering materials used to build these antennas are thick, thickness accommodation techniques must be applied to realize the same folding motions as the zero-thickness models. This paper presents a hexagonal twist origami pattern in thick materials using three different thickness accommodation techniques. These techniques are compared. The metrics used for comparison are packing efficiency, usable area, benefit to stability, and deployment methods. These metrics have also help to determine trends that can benefit the designer when selecting thickness accommodation techniques.
