| 摘要: |
| 为了研究小功率SPT(稳态等离子推力器)内部的磁场分布和性能特性,应用参数化方法研制了单线圈小功率SPT。利用简化模型计算了磁场分布,并与实验进行对比,对其整体性能特性进行了实验研究。磁场测量结果和计算结果基本吻合,说明简化计算模型的可行性；实验中SPT能够顺利点火,性能测试结果达到了设计要求,结果表明,SPT可稳定工作在100~450W；当出口最大磁感应强度为300Gs,梯度为300Gs/cm时,SPT效率较高。 |

| Abstract: |
| A single-coil SPT (Stationary Plasma Thruster) with low-power was developed using parametric method to study its internal magnetic field and performance characteristics. The simulation using the simplified model and experimental results of magnetic field are basically consistent with each other. It suggests that the simplification of numerical model is credible, and the basic performance of SPT is satisfactroy in power range of 100~450W. The SPT has high efficiency when the maximum strength of magnetic field is about 300Gs and 300Gs/cm of gradient near the channel exit. |
