Compact High Performance Plasma Propulsion System, Phase I

Metadata Updated: February 28, 2019

The Compact High Performance Plasma Propulsion System (CHPPPS) is an electric propulsion system for 12U [HTML_REMOVED] 27U CubeSats.[HTML_REMOVED] CHPPS is designed for high-value science missions which require high specific impulse, high reliability, and radiation tolerance.[HTML_REMOVED] CHPPPS includes a low power Hall Effect Thruster (HET), a hollow cathode for neutralizing the ion beam, a propellant management system, and a power processing unit (PPU).[HTML_REMOVED] The system is highly modular and appropriate for 12U [HTML_REMOVED] 27 U CubeSats in terms of size, mass, and power.[HTML_REMOVED] CHPPPS may be as small as 4U, depending upon the fuel load and specific component selection.[HTML_REMOVED] Thrust will be 3-8 mN, depending on the power supplied (60 [HTML_REMOVED] 135 W) and peak specific impulse will be [HTML_REMOVED]1100 s.[HTML_REMOVED] The thruster will be fueled with xenon or with game-changing iodine, which stores as a solid at very low pressure and much higher density than xenon.[HTML_REMOVED] The use of iodine significantly decreases spacecraft dry mass, and dramatically decreases propellant volume.[HTML_REMOVED] The impact of switching from xenon to iodine is most significant for volume limited spacecraft like CubeSats.[HTML_REMOVED] Whether the thruster is fueled by xenon or by iodine, the ion beam will be neutralized by a hollow cathode flowing noble gas.[HTML_REMOVED] The thruster will be powered by a compact, radiation tolerant power processing unit (PPU) previously developed for NASA and Air Force applications. [HTML_REMOVED]ACS may be provided by cold gas thrusters fed from the noble gas storage system. [HTML_REMOVED]In Phase I, the system design will be detailed and studied.[HTML_REMOVED] Work will include a proof of concept hardware demonstration at relevant power levels.
