dc.description.abstract Solar sails provides a propellant free propulsion system that converts a small portion ofsolar radiation to move a spacecraft. These structures require a large surface area and hence bound to utilize deployable concepts for storage and transport. In general, geometric effects due to membrane thickness are ignored during the design process of deployable membranes, which leads to excessive stretching ofmembrane and issues related to stowage and repeatability. This paper presents a modified fold line arrangement for spiral folding patterns with any regular polygonal shape hub to eliminate the adverse geometric effects caused by membrane thickness. The proposed modification is verified for a square shaped module with the help ofpaper models.
