Recent Advances in Space-Deployable Structures in China

Abstract

Deployable space structure technology is an approach used in building spacecraft, especially when realizing deployment and folding functions. Once in orbit, the structures are released from the fairing, deployed, and positioned. With the development of communication, remote-sensing, and navigation satellites, space-deployable structures have become cutting-edge research topics in space science and technology. This paper summarizes the current research status and development trend of space-deployable structures in China, including large space mesh antennas, space solar arrays, and deployable structures and mechanisms for deep-space exploration. Critical technologies of space-deployable structures are addressed from the perspectives of deployable mechanisms, cable-membrane form-finding, dynamic analysis, reliable environmental adaptability analysis, and validation. Finally, future technology developments and trends are elucidated in the fields of mesh antennas, solar arrays, deployable mechanisms, and on-orbit adjustment, assembly, and construction.
