Abstract
Based on the hexahedron module, a space deployable truss antenna is presented in the paper. The parabolic antenna can stow and deploy associated with the stretch and shorten of the diagonal members. The deployable power is acted by the tension spring in the diagonal rod, and no need for extra force. The geometrical relation of the whole structure’s rods is complex, so it is necessary to analyze the geometrical constraint of the structure from the deployed configuration to the stowed one. From the results of the structural analysis, the structure presented in this paper is practical.
