Space webs are lightweight cable nets deployable in space to serve as platforms for very large structures. Deployment and stabilization of large space webs by spin have gained interest because the rotational inertia forces are in the plane of rotation and the spin rate that determines the magnitude of the web tension can be chosen to meet the mission requirements. Nevertheless, a robust control method is required for a successful spin deployment. The control law used for the deployment of the Znamya-2 membrane reflector, for which a feedback-controlled torque is applied to the center hub, was applied here to a quadratic space web folded in arms coiled around the hub. To analyze the deployment, an analytical three-degree-of-freedom model and a fully three-dimensional finite element model were developed. The simulations indicate that it is favorable to deploy the web in just one step. It is also suggested that the simple analytical model can be used to determine important mission requirements such as the torque, power, and energy required for different deployment times.
