System Design of Solar Sail Deployment and its Effect on Attitude dynamics for Cube Satellite CNUSAIL-1
The CNUSAIL-1,which is currently being developed at the Chungnam National University,is a 3U-size CubeSat with 4 m2 sized small solar sail.The purpose of the CNUSAIL-1 is to successfully deploy the solar sail in Low Earth Orbit(LEO)and to perform de-orbiting using the sail membrane as a drag-sail.Deployment systems consist of quadrant sail membranes,four steel booms,and a spiral torsional.To produce high propellant,Kapton sheet with ultra-thin thickness(about 0.25 um)is prepared as the sail membranes.The proposed Steel booms are C-shaped with 0.2 mm wall thickness and have a weight of 72 g per meter.The deployer of 0.5 U is designed with a middle spindle and four guides to help booms spread smoothly.This paper describes a conceptual design and mechanism of the CNUSAIL-1 deployment system,and its performance is verified by ground tests in a low-friction environment.Additionally,the effect of the solar sail deployment on attitude dynamics is analyzed via numerical simulations by taking into account the velocity of boom ejection,the moment of the torsional spring,and the change of moment of inertia.
