Mass efficiency of strip-based coilable space structures

This paper presents a general semi-analytical study of the mass efficiency coilable plate-like space structures. A bending architecture based on four diagonal booms that support parallel strips is compared to cable-stayed in which vertical and cable stays at tip. Limiting conditions global buckling, local material failure, excessive deflection define design for each architecture. Considering pressure loads spanning several orders magnitude, optimal areal density structures size varying from few meters hundreds determined both architectures. Design charts designs are provided range sizes, loads, limits. It shown always lighter than architecture, percent over 30%.
