摘　　要：主要对0.1 kW微波等离子体推力器进行了地面试验和数值模拟研究。试验研究分析了影响推力器效率的因素;数值研究通过采用SIMPLE方法求解了N-S方程和采用FDTD方法求解了M axwell方程,分析了影响谐振腔内等离子体参数的因素。结果表明,微波功率、工质种类和质量流率是影响谐振腔效率的主要因素,而等离子体参数则主要受微波功率的影响。Experimental and numerical studies on 0.1 kW microwave plasma thruster were presented, and the factors which affect the efficiency of thruster were experimentally investigated. The factors affecting the parameters of plasma in cavity were analyzed by solving N-S equations with SIMPLE method and Maxwell equations with FDTD method. The conclusion shows that microwave power,propellant kind and mass flow are the main factors that affect the effficiency,and plasma parameters are affected by microwave power mainly.
