Fundamental study on a liquid propellant thruster using heated-surface sustained combustion

The author designed a new liquid propellant thruster using Joule heating assisted combustion in order to develop dual-mode space propulsion device that has enhanced performance. Assisted combustion allows the thruster to have two modes: electric propulsion mode where the thruster yields relatively high specific impulse and low thrust, and chemical thruster mode where it provides high thrust and low specific impulse. In this study, a prototype was tested in order to evaluate performance of the designed thruster.
