This paper reports on Moog's efforts to support the design, development, assembly and test of an electric propulsion xenon feed system for a flight technology demonstration program. Major accomplishments include: (1) Utilization of the Moog Proportional Flow Control Valve (PFCV), for the purpose of propellant isolation, pressure, and flow control. With pressure transducer feedback, the PFCV has successfully fed xenon to a 200 watt Hall Effect Thruster in a Technology Demonstration Program. The feed system has demonstrated throttling of xenon, from a very high inlet pressure of 2200 psia, through single stage modulation, to low, absolute pressures of 2.5 to 5.5 psia, accurately controlling them to within +/- 0.025 psia with the PFCV; (2) Integration, and manifolding of an entire flight Propulsion System pneumatic circuit; (3) Charging of a flight Propulsion System with certified clean xenon gas for flight application.
