S192012 Development Behavior of Convex Tapes for Membrane Space Structure

Abstract

Recently, deployable membrane structure has been applied to deorbit mechanism for small satellite. One way to deploy membrane structure is to use convex tapes as extension booms. This membrane deployment mechanism is simple and lightweight. Convex tapes winding around a spool store strain energy. Putting some guide rails around the spool, the convex tapes unwind from the spool and extend straight along the guide rails like extension booms. We will make two kind of guide rails and perform deployment test. In this report, we will show deployment dynamics of convex tapes, and show result of two kind of examination.
