摘要

本文提出了磁性离子液体电喷雾推力器的新概念。该推力器在外加磁场作用下工作电压较低，被命名为低压离子液体电喷雾推力器(LV-ILET)。利用喷射针作为发射极，亥姆霍兹线圈施加外磁场，演示了LV-ILET的工作原理。实验结果表明，在没有外加磁场的情况下，稳定工作电压可以降低到87%。在相同的工作电压下，外加磁场可以显著增加LV-ILET的发射电流。由于推力与发射电流呈线性关系，LV-ILET可以利用外加磁场和推进剂的磁化特性来降低工作电压或增加推力。

Verification of a Novel Electrospray Thruster with Magnetic Ionic liquid Propellant

A new concept of magnetic ionic liquid electrospray thruster(ILET) is proposed in this paper. The thruster uses a lower working voltage with the action of an applied magnetic field, and is named as low-voltage ionic liquid electrospray thruster(LV-ILET). A jet needle is used as the emitter and the Helmholtz coil is used to apply an external magnetic field to demonstrate the working principle of the LV-ILET. The experimental results show that the stable working voltage could be reduced to 87% of that in absence of an applied magnetic field. Under the same working voltage, the applied magnetic field can significantly increase the emission current of LV-ILET. Due to the linear relationship between the thrust and the emission current, LV-ILET can either reduce the working voltage or increase the thrust with the help of the applied magnetic field and the magnetization characteristics of the propellant.
