Abstract : This report describes effort to determine the technical feasibility of measuring the performance of a pulsed electrothermal thruster on liquid hydrogen propellant. The design of a 5 kW thruster is presented, including the capacitive pulse forming network, arc discharge characteristics, nozzle performance and predicted specific impulse and thrust. A thermal model is discussed which treats and solves the problem of liquid hydrogen it is concluded that a Phase II test should concentrate on water and/or hydrazine, and liquid hydrogen testing should be postponed to Phase III. Keywords: Electric propulsion, Pulsed electrothermal propulsion; Liquid hydrogen propellant.
