After the primary payloads deploy, explosive bolts release the Solar Blade from the launch vehicle.  Cold gas thrusters on the stowage craft null out the spacecraft tumble and point the sail core at the sun. A containment ring slides away from the blade roll tips, torsion springs drive the struts and blade rolls outward, and the blade pitch motors level the blade rolls. Then, the propulsion system spins up the spacecraft to 60 rpm while maintaining line of sight with the sun.  With the proper spin rate and orientation obtained, the stowage vehicle/spacecraft core release device fires, after which the blade deployment motors slowly and symmetrically feed out the blades.  As the blades deploy, a collective pitch maneuver maintains the spin rate as needed. The nominal operational spin rate at the completion of deployment is 1 rpm.
