The primary performance parameters of the space cable-strut deployable articulated mast was derived which can evaluate the space cable-strut deployable articulated mast performance. The relationship between primary performance parameters and geometrical feature parameters of space cable-strut deployable articulated mast was analyzed and studied. The expressions of line density, packaging efficiency, bending stiffness and bending strength of the mast were derived. The influence of mast-s material character to its performance parameters was analyzed. The stability problem of space cable-strut deployable articulated mast was discussed, and the condition of local instability and global instability was analyzed. The mast was designed based on two constraints modes of bending strength constraint and bending strength with bending stiffness constraints. The relation equations of geometrical parameters and line density of the mast relate with its bending strength and bending stiffness were established. The design results were analyzed and compared with the parameters of the American able deployable articulated mast.
