Analysis of the Principle, Applications and Improvements of Foldable Structure for Deep-space Exploration

As a matter of fact, deployable structures, a technology that has been widely used in deep-space exploration since the 1960s, are receiving more attention due to its applications in various conditions. With this in mind, this article aims to illustrate several space deployable structures available in recent years that have been adopted in the deep-space exploration. To be specific, the main content that have been applied in the deep-space exploration includes deployable antenna, deployable solar arrays and deployable surfaces. In this study, after introduction of the structures, some explanations about the operation of these unique equipment are made. According to the analysis, the current limitations for the state-of-art designs are also clarified. At the same time, the future prospects are demonstrated based on the evaluations. In conclusion, the article tries to give a brief review of the already existing technology and makes an effort to further explore the future potential of these structures.
