Innovative design of modular pantograph tensegrity deployable cylindrical reflectors

Abstract

To solve the problems of high areal density and low packaging ratio in available deployable cylindrical reflector antennas, an innovative design concept named the modular pantograph tensegrity deployable cylindrical reflector is proposed. The innovative design mainly consists of a pantograph tensegrity deployable truss, flexible cable nets, and reflective wire mesh surface. Based on the modular design concept, the pantograph tensegrity deployable truss can realize synchronous deployment in both parabolic and cylindrical directions. Compared with two typical deployable cylindrical reflectors, the proposed design has the advantages of lower areal density and higher packaging ratio. Simulations of performance analysis demonstrate the benefits of the innovative design.
