“…For example, in aluminium-polymer-aluminium laminates, cracking of the outer layers exposes the polymer to environmental radiation. Senda et al [29] found that the stiffness, evinced by the natural frequency, of a rigidized (strain-hardened aluminium laminate) inflated folded boom was reduced to about one-third compared to an unfolded boom; no analytical or numerical studies have been found to characterize this effect.…”

Inflatable structure is an attractive candidate as ultra-light space structures with high packaging efficiency. They consist of flexible membrane and some components for the deployment. For such pneumatic structure with membrane, the damage of the membrane caused by space debris is one of serious problems for the utilization in space. To solve the problem, multi-cellular inflatable structures are proposed. Inflatable structures composed of multi-cells are robust against the damage of membrane. In this paper, a new type of inflatable cylinder which is composed of sealed multi-cells was investigated. Because deployment of the structure can be driven by the gas pressure of the sealed multi-cells, no complex components such as gas tanks and electric valves are required for the deployment. The fundamental characteristics of the deployment are investigated experimentally. As a result, it is shown that the inflatable cylinder composed of sealed multi-cells can achieve the deployment with simple hold-release mechanism even though some cells are damaged. Furthermore, by applying with inner bellows and outside constraint wires, the deployment sequence can be controlled and almost straight deployment can be realized.

A number of folding mechanisms have been proposed for spaceborne deployable booms/masts based on origami patterns. The packaging and deployment of a cylindrical boom with Yoshimura pattern are analyzed in this paper. At first, the detailed design of the Yoshimura pattern is discussed, and geometrical expressions for various important parameters like radius of packaged boom, packaging efficiency and inside residual volume after complete folding are obtained to investigate the packaging behavior of the boom. Then, the deployment of a single story Yoshimura cylinder is simulated using FE software ABAQUS. The folded shape of the boom is modeled using pin-jointed wireframe technique, and a uniform nodal displacement is provided to the top polygon, and corresponding axial strains in the fold lines are analyzed numerically. The influence of the number of origami units on packaging and deformation behavior is also discussed. The results show that the fold line deformation decreases as the number of origami units increases, but this also decreases the packaging efficiency of the boom. Moreover, the expansion coefficient is defined to relate the circumferential strain with applied longitudinal strain.
