Modular Packaging Concept for Micromachined Field Effect Electrostatic Propulsion.

A modular propulsion system includes an array of micromachined field effect electrostatic propulsion devices, each of which is an assembled micromachined device including an array of field effect electrostatic propulsion thrusters, a fuel container of propellant using passive plumbing, electronic power and command controls, with the array of devices disposed about and on a surface of a spacecraft for providing diverse propulsion needs.
