Abstract: A brief recommendation of status of internal process studies on arcjet thruster was given and the influences of this process on performance of arcjet thruster were analyzed.Despite the difficulties of these studies arising from rigour cirumstances in arcjet thrusters,so many progresses were in both experimentation and theory researches.Pressure measurements,electrostatic measurements,spectrum measurements and laser fluorescence induce measurements are main means to reveal internal and outer flow(plume) structures.The sophisticate numerical models with the capacities of reflecting complex processes such as chemical and thermal nonequilibrium were also established.
