Experiment and performance analyse on low power arcjet

Arcjet is the highlight of investigation and application in world because of its high specific impulse, high ratio of thrust and power. This paper introduces primary constitution of experiment system on low power Arcjet and analyzes experiment projects. Four types of thruster were employed to present performance test, primary operation performance parameters and experiment results analysis are presented. The test results show that thruster performance is better at small constrictor diameter and nitrogen as propellant. The conclusions obtained in this paper provide a reference for the optimization design of low power Arcjet thruster.
