Abstract: A two-stage projection scheme of space nets is proposed by using “outstretching first and opening later” idea in parachute inflation process, and a numerical simulation model is developed. In the proposed scheme, the projection process of space nets is divided into two successive courses: the first-stage of outstretching course and the second-stage of opening course, through which the process is controlled step by step to pull out the space nets regularly and ordinarily, and avoid their twining, penetration and knotting problems. Through a contrastive analysis of the numerical simulation result and the experiment result, the numerical simulation model is tested and verified. The two-stage projection scheme of space nets and the numerical simulation model developed in this paper provide a reference way to carry out optimization design of space nets.
