摘　　要：螺旋波无电极先进推力器(HEAT)是一种新概念的等离子体推力器,具有比冲高、寿命长、无电极烧蚀、可靠性高的优点,适用于未来的深空探测等长时间飞行任务。首先介绍了推力器的结构和工作原理,重点介绍了李萨如加速机制的原理;分析了HEAT的电子运动轨迹。并用等离子体的漂移扩散模型推导出了具体的推力计算公式,在粒子的回旋半径和推力器的比值为特定的值的时候,推力有一个最大值。理论分析结果为后续的推力器的设计提供指导。HEAT is a new concept of plasma thruster,having the advantages of high specific impulse,long life,electrodeless ablation and high reliability. It is suitable for long time flight missions in deep space exploration in the future. Fistly,the structure and working principle of the thruster are introduced,and the principle of lissajous acceleration mechanism is introduced. The electronic trajectory of HEAT is analyzed. A formula of calculating the thrust is derived using the drift diffusion model. When the ratio of the particle radius of gyration and thruster is a specific value,there is a maximum thrust. The results of the theoretical analysis provide guidance for the design of the thruster.
