Space deployable mechanics: A review of structures and smart driving

Abstract

Space deployable structures are able to be deployed from a folded state to a predetermined or desired configuration. They are superior in terms of spatial packaging ratio, controllability, and structural complexity, in order to solve the space limitations for aerospace vehicles. Therefore, they have been applied in structural designs and concepts for various aerospace missions, including space support booms, space deployable antennas, solar panels, as well as flexible solar sails. Recent development of advanced manufacturing technologies and applications of novel smart materials and structures, brings new degree of design freedom to space deployable mechanics, inspiring novel space deployable mechanisms, especially for smart driving and control strategies. Here, we present a review on development of mechanics and smart driving of space deployable structures. Advantages and limitations for various deployable mechanisms are also presented to reveal further insights. The trends and future deployable mechanics are directed by further advancements in terms of modularisation, intelligences, and deployment precision. Multi-disciplinary cross-integrations are leading the way for future breakthroughs in novel deployable mechanics and intelligent driving control for space explorations.
