Coupled Attitude-orbit Dynamics and Control of Solar Sail by Moving the Center of Mass
, M.Sc. Thesis Sharif University of Technology ; Asadian, Nima (Supervisor)
Abstract
In this thesis, firstly we have developed a coupled dynamic for the orbit and attitude of a solar sail. Secondly, we found an optimal trajectory from the Earth to Mars and tried to control the system on the optimal trajectory by a control mechanis which moves the center of mass of the sail. The solar sail is considered to be rigid and Ideally reflective which means the sail reflects the full extent of the photons it receives. Adjusting the center of mass of the sail is done by changing the position of two sliding masses rode on two rails perpendicular to each other. Moving the center of mass of the sail brings about a change in the attitude of the sail which then causes a deflection in the...
