ABSTRACT:
The deployment system comprises a plurality of parallel jack screws securely supported at their respective bases to a deployment portion of the spacecraft. The jack screws are rotatable with respect to that deployment portion. A synchronization chain is connected to the jack screws to insure precise timing between the screws. An electric motor provides rotation of the jack screws. A payload is provided having attach fittings located thereon for engagement with the jack screws. Prior to deployment, the payload is mounted to the jack screws. During deployment, synchronous rotation of the jack screws is provided allowing the payload to translate off the ends of the jack screws. Thus, the jack screws simultaneously serve as guides for the payload, providing a precise trajectory, and providing the driving force to eject the payload from the spacecraft.
