Dynamics and Control of Inflated Satellite Components

Abstract

The instrumentation purchased under this DURIP was in support of an ongoing effort to understand the dynamics of inflated satellite components and then to provide both shape and vibration control based on the discovered dynamics. Inflatable space-based devices have become popular over the past decade due to their minimal launch-mass and launch-volume. Once inflated, these space structures are subject to vibrations induced mechanically by guidance systems and space debris, as well as thermally-induced vibrations from variable amounts of direct sunlight during orbit around the Earth. Understanding the dynamics of inflated components and controlling the shape and vibrations of spaced-based structures is critical to ensuring optimal performance.
