“…4 For the solar array application, the desired final form is flat, but it may also be possible to deploy into a concave or convex form as well (e.g., for satellite receivers). [14][15][16] The folding design is based on the origami flasher model. 17 In origami, paper is usually assumed to have zero thickness, which is a close enough approximation for origami folding patterns to work.…”

HanaFlex is a new method for deployment from a compact folded form to a large array derived from the origami flasher folding pattern. One of the unique features of this model is that the height constraints of the stowed array do not limit the deployed diameter. Additional rings can be added to increase the deployed diameter while only minimally increasing the stowed diameter. Larger solar arrays may enable longer missions in space, manned missions to distant destinations, or clean energy sources for Earth. The novel folding design of the HanaFlex array introduces many new possibilities for space exploration. This paper demonstrates the performance of the HanaFlex array in four areas: deployed stiffness, deployed strength, stowed volume specific power, and mass specific power.

This paper discusses what has been found and what will be found using conceptual "origami" models to develop deployable space structures. The study covers the following: (i) one-dimensional structural elements, which are axially buckled inflatable tubes; (ii) two-dimensional elements, which are deployable membranes, such as solar arrays and solar sails; and (iii) deployable elements in nature. The study clarifies what design considerations are necessary to adapt the basic concepts to actual space structural hardware, and several limitations of origami models are discussed. Regarding the last subject, this study envisions future space structures using conceptual origami models that imitate three-dimensional deployable structures in nature, such as flowers and insect wings.

“…The influence of membrane thickness and crease density on the driving force during the deployment of wrapping membrane structures was also investigated by Arya and Pellegrino [21]. The methods which considered thickness in the roll-up of the z foldingmembrane were proposed and classified by Sakamoto et al [22], including two methods that kept the creases straight. The axis-shift and tapered panel methods were applied to add non-zero thickness to single-vertex multi-crease rigid origami to explore a feasible solution.…”

Deployable membrane structures have received wide attention in many engineering applications, such as the military, aerospace, and aviation. Their properties of light weight and high storage ratio meet the requirements for aerospace exactly. In this paper, the wrapping deployment of membrane structures inspired by leaves are simulation-analyzed for prospective improvement. Three leaf-inspired patterns are investigated and discussed from the corresponding paper-craft design principles and deployment process perspectives. The deployment performance evaluation system according to the factors effecting working performance including maximum stress, driving force, maximum strain energy, smoothness index, and maximum folding height is established based on the results of the simulation analysis. Then, a comparison between the three patterns is carried out based on the deployment performance evaluation system. Moreover, it is found that adding creases reduces the folded height but the development performance gets worse. There is a balance between the folding ratio and development performance when the additional creases are added. The results can provide useful suggestions for designing wrapping deployment structures.
