A deployable mast for solar sails in the range of 100-1000Â m

The purpose of this paper is to introduce a new deployable mast design that may provide a means to scale up solar sails to very large dimensions. The paper describes the basic analytical approach for truss beams, compares this new design with the state-of-art truss used in NASA's solar sail development work, and provides analyses of novel applications enabled by the mast design.
