摘　　要：为满足50 kg以下卫星的轨控需求,研制了M2型微波离子推进系统。该推进系统利用微波电离原理,具有启动快、功耗低、集成度高、推力连续可调的特点,系统额定功耗40 W,额定推力0.3 mN,比冲1200 s,是一种全新的伺服型离子推进系统。在地面真空环境下进行了推力器7000 h寿命与2000次重启试验,充分证明M2型离子推力器具有极高的使用寿命和可靠性。M2型微波离子推进系统于2021年4月27日随起源太空NEO-1卫星发射升空,2021年5月10日在轨点火成功,2021年8月20日在轨推力引出成功,输出推力0.31 mN,比冲1272 s,各项功能正常,遥测结果与地面数据一致。In order to meet the needs of on orbit missions for micro-nano satellites below 50 kg,the M2 microwave ion propulsion system was developed.The propulsion system uses the principle of microwave ionization,has the character‐istics of instant fire,low power consumption,high integration,and continuously adjustable thrust.The system has a rated power consumption of 40 W,a rated thrust of 0.3 mN,and a specific impulse greater than 1200 s,which is a new servo-type ion propulsion system.In the ground vacuum environment,7000 hours of life and 2000 restart tests were carried out,proved the high reliability and high stability of the M2 ion thruster.The M2 microwave ion propulsion system was launched on April 27,2021 with the NEO-1 satellite.The propulsion system was successfully fired on orbit on May 10 and generated thrust on August 20,2021.The calculated thrust was 0.31 mN,and the specific impulse was 1272 s.All func‐tions of the propulsion system were normal,and the test results were consistent with the ground test data.
