TY  - JOUR
AB  - A Hall Effect Thruster propelled by water vapour is investigated at the Imperial Plasma Propulsion Laboratory. For that purpose,a water vapour feed system is designed, optimised and tested, with the major objective of keeping water in vapour state at all times.This system primarily consists of a mass flow controller, a flow restrictor, and a heating and pressure monitor system capable ofidentifying under which conditions water condensation occurs. A hanging pendulum thrust balance is used to measure the thruston the power range of Pd = 600 − 1600 W. Different magnetic field strengths and mass flows are investigated to determine theconditions in which the highest efficiency can be achieved. Then, a comparison between water vapour and oxygen (intended tobe the propellant of a water electrolysis Hall Effect Thruster) is included. The results show that oxygen is approximately 20 %more efficient than water vapour under the same operating conditions. Overall, the highest thrust measurement recorded with watervapour was 20.0 ± 0.2 mN; with a specific impulse of 2039 ± 20 s and an anode efficiency of 12.5 ± 0.3 % at the largest dischargepower of investigation (Pd = 1600 ± 1 W).
