Colloid Thruster for Attitude Control Systems (ACS) and Tip-off Control Applications, Phase I

Completed Technology Project

Project Introduction

Colloid Thruster for Attitude Control Systems (ACS) and Tip-off Control Applications, Phase I
We propose to develop and test key technologies needed for an integrated, high thrust colloid thruster system with no moving parts, for spacecraft attitude control and tip-off rotation cancellation. Busek has already successfully demonstrated the use of porous substrates as planar emitters for colloid thrusters. In this proposal we will pursue enabling technologies for such a thruster, such as a passive feedsystem and an isolation membrane for separating the propellant in the reservoir from the thruster head prior to launch. Advancements to date suggest viable approaches for the development of a cost-effective, reliable, and flexible thruster configuration. More »
