  1. Much works has been distributed to the development of a vacuum system to simulate the outer space and a measurement system to test the arcjet performance. ignition experiments in various operational modes have been done with argon as propellant. macroscopical working parameters including thrust, mass flow rate, voltage, current, inlet pressure and vacuity are obtained by the test measurement system and actual performance parameters including specific impulse, thrust efficiency, ratio of thrust and power and ratio of power and mass flow are calculated

    以氬氣作為,在不同工況下行點火實驗,測獲得了其工作力、電弧電壓和電流、流率和弧室壓力等宏觀參數,得到了不同實驗條件下其工作的實際沖、力效率、力/功率以及功率等性能參數,分析了流率、電弧功率、電弧加熱發動機電弧室結構尺寸等因素對其性能的影響,為數值模擬研究和實際的低功率電弧加熱發動機優化設計及研製提供了實驗基礎。
