摘要： 为了精确测量小功率电推力器的小推力 ,从理论上提出了一种小推力测量的方法 ,即利用电磁反馈补偿方法使推力测量天平工作在随遇平衡状态 (或接近于随遇平衡状态 ) ,消除气路和电路连接的影响 ,电磁力反馈补偿推力器产生的推力。通过对电弧加热等离子体推力器 (Arcjet)的热实验 ,测量装置测量了不同工况下的推力值。实验证明此测量方法可准确测得电推力器工作的小推力。

Abstract: A small thrust measurement method was presented in theory for precision measurement of small thrust of low power electric thruster, namely when thrust measure balance is in the state of indifferent equilibrium (or near to the state of indifferent equilibrium), electromagnetism force feedback compensation can eliminate the influence of connection of gas line and electric wire and feedback electromagnetism force can compensation thrust of thruster. Thrust values of different operational mode of arcjet thruster were measured. Experiment validated that this measure method can measure small thrust of electric thruster accurately.
