“…The purpose of this methodology is to replicate the operating condition of the tape-spring during deployment in space. In 2017, Mao et al [158] used a GOLS that consisted of a set of braided cords that suspend the deployable structure. This allowed the structure to deploy along a plane parallel to the ground, resorting to a set of soft extension springs that compensated the changes in distance between the hanging points.…”

“…However, several other researchers made relevant contributions. Researches with similar approaches include: Seffen and Pellegrino (1999) [213] for the full deployment simulation and initial design of a single tape-spring, Boesch et al (2007), Givois et al (2001) and Jeong et al (2016) [26,89,110] for structures with multiple tape-springs, Mao et al (2017) [158] for integral slotted hinges, and Cook and Walker (2016) [49] for the use of tape-springs in the deployment of an inflatable structure.…”

“…Generally, these systems consist of vertical cords attached to discrete points of the structure, applying a total force equal to its weight. In the simplest case, the cords can be attached to a fixed point [9] [36] and soft springs can be used to allow extension of the cords with minimal variation of their tension, Fig. 5(a).…”

This paper investigates the deployment behavior of lightweight flexible space structures consisting of thin shell components. An extensive and detailed study of a symmetrically folded structure that dynamically deploys by releasing its stored elastic energy is presented. The challenges involved with ground testing of this structure are discussed, and a suspension system that allows propagation of the elastic folds is proposed. The dynamics of two 1 m-scale structural prototypes was measured using high-speed Digital Image Correlation. It is shown that, for the tests considered, the elastic folds remain stationary and behave as elastic hinges, resulting in a symmetric and repeatable deployment. Deployment experiments in air and vacuum showed that air mass significantly affects the dynamics of the structure, slowing its deployment by 70 %. However, this effect becomes negligible if the deployable structure is not covered by a film. A finite element model of the deployment is presented. The effects of air are approximated by an added mass to the structure, calculated through simple geometric arguments. This model shows good agreement with experimental results without increasing the associated computational time.

“…The centers of curvature in the two configurations are on the same side of the shell. The transformation between two configurations of a bistable composite cylindrical shell can be accomplished through two forms of external force generated from actuators: pulsed external force [31], [32] and continuous external force [33], [34]. In this study, a bistable asymmetric glass fiber-reinforced polymer (GFRP) composite cylindrical shell is used as the antenna's substrate to achieve reconfigurability.…”

This paper presents a wideband pattern-and polarization-reconfigurable antenna based on bistable composite cylindrical shells. This antenna, which includes seven radiating metal strips, uses bistable anti-symmetric glass fiber-reinforced polymer (GFRP) composite cylindrical shells as the substrate to achieve reconfigurability without the need for redundant structures or semiconductor devices. This bistable GFRP substrate has two stable cylindrical configurations: extended structure and coiled-up structure. Therefore, by transforming the configuration, the radiation patterns of the proposed antenna are changed, and simultaneously, the polarization is switched between left-handed circular polarization (LHCP) and right-handed circular polarization (RHCP). A prototype of the proposed antenna is fabricated and measured. The measured results indicate that the antenna can operate in the frequency range from 2.3 to 3 GHz in the two configurations. The proposed antenna can be utilized as the payload of a satellite.INDEX TERMS Wideband, pattern-reconfigurable antenna, polarization-reconfigurable antenna, bistable cylindrical shells.
