Deployment analysis of a spinning space solar sail
The large scale spinning solar sails have been successfully used for the deep space research exploration in recent years.The spinning solar sails can be considered as a rigid-flexible multibody system mainly composed of central rigid spinning hub, flexible thin tethers, sail membranes, and tip masses.A simplified “IKAROS (Interplanetary Kite-craft Accelerated by Radiation of the Sun) model is established in this paper by using the Absolute-Coordinate-Based (ACB) method that combines the Natural Coordinate Formulation (NCF) describing rigid bodies and the Absolute Nodal Coordinate Formulation (ANCF) describing flexible parts.The initial configuration of the system in the second stage deployment is obtained through both dynamic and static analyses.The deployment dynamics of the system is studied.The huge set of stiff equations of motions is solved by using the Generalizedalpha method.
