Abstract: Multi-functional coilable thin-walled structures that can be implemented within space-based satellite modules, and methods for their manufacture are provided. Multi-functional coilable thin-walled structures are comprised of at least one longeron that is capable of rolling and collapsing upon itself. In some embodiments, the coilable thin-walled longeron is a flange longeron. The flange longeron contains at least two major regions: a web and a plurality of flanges. The web region comprises portions of flanges that are bonded to one another. The plurality of flanges separate from one another on the same end of the web region. The plurality of flanges are similar in thickness and shape.

Abstract: An actively controlled deployment mechanism with a plurality of centrally controlled rollers as well as outer rollers that are configured to apply a pressure across the compactable portion of the deployable structure. The active control can be implemented though control motors and control loops programed to control the rotation of the rollers. Additionally, the actively controlled deployment reduces the need for bulky and heavy booms with high tension guide wires for the deployment of the structure.
