1. 1. Sunshade Demonstrator Spacecraft Earth Sphere of Influence Escape Using a Propellant-free AOCS

   University essay from KTH/Rymdteknik

   Author : Leonardo Ricci; [2021]
   Keywords : Solar sail; Solar radiation pressure; Attitude control; Escape trajectory; Centre of pressure; Disturbance Torques; Eclipse.; Solsegel; Solstrålningstryck; Attitydkontroll; Flyktbana; Tryckcentrum; Störningsmoment; Eclipse.;

   Abstract : This thesis provides insights to what is peculiar about a solar sail attitude and orbit control system and provides the assessment, in the form of a feasibility study, of the effectiveness of sail tip vanes as a control hardware to escape the Earth sphere of influence. The demonstrator aims to prove the technology for the Sunshade project, a constellation of solar sails located at the Lagrangian point L1 to obscure part of the solar radiation directed towards earth.
