Summary
HELIOS deployment sequence. After detumble, acquisition and orientation to the sun, blade reels are released via a burn wire. Deployment is actuated by springs. Tensioned cables connect the deployed truss to the central spacecraft bus. Once the blade truss is deployed magnetic coils are used to spin up the core spacecraft to the nominal pre-blade deployment spin rate. After a systems checkout, a synchronized, controlled blade deployment is intiated. The blade camera mast is deployed at an intermediate blade deployment radius, and blade pitch control is activated to manage overall spin rate via solar radiation pressure induced torque.
