Self-Deployable, Self-Stiffening, and Retractable Origami-Based Arrays for Spacecraft

the search for the self in becketts theatre: waiting for godot and endgame

this thesis is based upon the works of samuel beckett. one of the greatest writers of contemporary literature. here, i have tried to focus on one of the main themes in becketts works: the search for the real "me" or the real self, which is not only a problem to be solved for beckett man but also for each of us. i have tried to show becketts techniques in approaching this unattainable goal, base...

Origami-inspired deployable auxetic metamaterials

Developing complex spatial objects from a fl at sheet of material using origami folding techniques has long attractedattention in science and engineering. Recent research has shown that in origami-based deployable folded sheetmaterials, such as Miura-ori, metamaterial properties of the patterns are basically because of their folding geom-etry [1, 2]. In this study, we employ tai...

Self-organized origami.

In origami, form follows the sequential spatial organization of folds. This requires continuous intervention and raises a natural question: Can origami arise through self-organization? We answer this affirmatively by examining the possible physical origin for the Miura-ori leaf-folding patterns that arise naturally in insect wings, leaves, and other laminae-like organelles. In particular, we po...

Advanced Deployable/Retractable Solar Panel System for Satellite Applications

Modern low earth orbit (LEO) satellites that require multi-mission flexibility are highly likely to be repositioned between different operational orbits. While executing this process the satellite may experience high levels of vibration and environmental hazards, exposing the deployed solar panel to dangerous stress levels, fatigue and space debris, hence it is desirable to retract the solar sa...
