利用高功率毫米波发生器回旋管对多脉冲微波束流推进器进行了实验研究。对不同直径和锥角的圆锥推力器模型进行了试验。在第一和第二脉冲的动量耦合系数Cm分别估计从飞行轨迹测量。结果，发现Cm在后期脉冲时降低。比值Cm 2/Cm 1主要取决于脉冲重复率而变化。最佳推力器规模的允许最大重复频率将低于60 Hz。
An experiment on a multi‐pulsed microwave‐beaming thruster was conducted using a high power millimeter‐wave generator, gyrotron. Conical thruster models with various diameters and cone angles were tested. The momentum coupling coefficients Cm at the first and second pulses were separately estimated from the flight trajectory measurement. As a result, Cm was found decreased at latter pulses. The ratio Cm2 /Cm1 was varied mainly depending on the pulse repetition rate. The allowable maximum repetition rate for the optimum thruster scale would be lower than 60Hz.
