Based on the results of a numerical simulation, a possibility in principle is shown to achieve an effective magneto-induction correction of high-gradient plasma expansion from a localized arc source and a respective severalfold increase in the thrust pulse with a steepness of the induction rise in the accelerator on the order of 104 T/s. In these conditions, a pulse-periodic mode of the device operation is required with a delay of the current pulse front in the magnetic field source relative to the ignition voltage pulse in the plasma source, which is determined by the expansion velocity of the plasma cloud within the device.

基于脉冲磁场的脉冲电弧等离子体电推力优化

基于数值模拟的结果,原则上显示了一种可能性,即实现对来自局部电弧源的高梯度等离子体膨胀的有效磁感应校正,以及推力脉冲的几倍增加以及感应上升的陡度在 104 T/s 数量级的加速器中。在这些条件下,需要设备操作的脉冲周期模式,其中磁场源中的电流脉冲前沿相对于等离子体源中的点火电压脉冲有延迟,这由等离子体云的膨胀速度决定设备内。
