Development of a Next Generation Low Power Small Satellite Thruster

摘要

This report results from a contract tasking Surrey Satellite Technology, Ltd., as follows: The Grantee will investigate the performance trade-offs for micro-satellite propulsion between a next-generation resistojet using xenon propellant and carbon heaters, and other methods. These include existing resistojets and micro-pulsed plasma thrusters. Development and testing of carbon monolith heaters and a prototype thruster will be performed. Pressure and temperature of the gas in stagnation chamber will be measured. Specific impulse and thrust will be measured if the facility at ESTEC is available: otherwise it will be estimated based on mass flow.
