Abstract:

This report is a technical summary of the system development phase of the Colloid Advanced Development Program. The program objective was to flight-qualify and radiation-harden a high performance colloid thruster system. Two prototype systems were developed. One operated in a constant current control mode, the other in a constant power, constant mass flow control mode. At start-of-life, the thruster produced 1-millipound thrust and greater than 1350 seconds specific impulse for 70 watts of input power to the propulsion system. The propulsion system included a 432-needle array thruster, thermionic tungsten filament wire neutralizer, propellant storage and feed system, and a power conditioning and control system.
