Preliminary Exploration of Approaches to Increase the Stability of Flat-Foldable Origami-Adapted Designs in the Open, Flat State

Weber State University

Deployable spacecraft-based systems are benefitted from origami-adapted systems because they can be folded compactly and then deployed to larger areas. This unfolding motion must be stopped and held in specific configurations. In the case of reflectarrays, the panels need to deployed to flat and be kept there. Strain energy can be utilized to stabilize these systems. This works shows three ways, based on three different thickness accommodation techniques, that strain energy may be used to stabilize the systems in their deployed, flat positions. Additionally, each technique shown creates co-planar top surfaces to benefit reflectarray antenna design cases.
