Other AbstractDC discharge in arcject thruster is used to heat up the injected propellant,which is then accelerated and ejected from a de Laval nozzle at high speed to create thrust.The performance of the arcjet thruster is affected by the complex flow and heat transfer process in its nozzle to a large extent.Performance of arcjet thrusters with radiation or regenerative cooled nozzle was compared in a wide range of operating parameters.Argon,nitrogen,hydrogen and hydrogen-nitrogen mixture were used as the propellants with the feeding rate of 4~270 mg/s.The arc current was set to be 4~12A and the experimental chamber pressure was below 20Pa.Evolutions of nozzle temperature,arc voltage and the generated thrust were measured and the dependence of arcjet performance on the nozzle temperature was discussed
