摘要/Abstract

摘要： 为了探究微波推力器的推力性能，采用三丝扭摆推力测量方法对微波推力器独立系统开展推力测量实验，同时分析三丝扭摆推力测量装置的数理模型并实验测定其不确定度，由此判断实验测量结果的可信度。推力测量结果表明，现有实验条件下三丝扭摆推力测量装置能测出不低于3mN的推力，其相对不确定度为14%；在三丝扭摆推力测量装置的推力测量范围内，没有测出微波推力器独立系统显著的推力，而是在230W微波功率输出条件下测出推力在±0.7mN范围内波动，相对不确定度大于80%。

Abstract: In order to explore the thrust performance of microwave thruster，the thrust produced by microwave thruster system was measured with three-wire torsion pendulum thrust measurement system and the measurement uncertainty was also studied，thereby judging the credibility of the experimental measurements. The results show that three-wire torsion pendulum thrust measurement system can measure thrust not less than 3mN under the existing experimental conditions with the relative uncertainty of 14%. Within the measuring range of three-wire torsion pendulum thrust measurement system，the independent microwave thruster propulsion device did not detect significant thrust. Measurement results fluctuate within ± 0.7mN range under the conditions 230W microwave power output，and the relative uncertainty is greater than 80%.
