微推进器是微型航天器的重要功能器件。实时测量微推进器不同时刻推力的瞬时值对研究微推进器的工作机理很有帮助;对于工作在低频多脉冲条件下的推进器,通过实时测量微推力的瞬时值,也可以获得多脉冲微推力的信息。提出了一种瞬态微推力的实时测量方法。初步仿真计算结果表明,此方法具有很好的跟踪特性,计算精度较高,可用于低频多脉冲微推力以及连续微推力实时测量。
Micro thrusters are important functional devices for miniature spacecraft. Real-time measurement of the instantaneous value of the thrust of the micro-thruster at different time is very helpful for studying the working mechanism of the micro-thruster. For the propeller working in the condition of low frequency and multi-pulse, the instantaneous value of the micro-thrust can also be obtained to obtain multi-pulse micro Thrust information. A real-time measurement method of transient micro thrust is proposed. The preliminary simulation results show that the proposed method has good tracking characteristics and high computational accuracy. It can be used in low-frequency multi-pulse micro-thrust and continuous micro-thrust real-time measurement.
