在带有一维喷管的微波束流推进器中，等离子体和激波在喷管中传播，吸收微波能量。在这项研究中，在推力器的压力历史测量使用压力计。在推力器壁测得的压力历史表明，在等离子体在喷嘴中传播的恒定压力。对冲击波和等离子体传播速度的测量结果表明，冲击波和等离子体以相同的速度传播。这些结果表明，脉冲爆震发动机模拟推力产生模型对一维推力器是成功的。
In a microwave beaming thruster with a 1‐dimensional nozzle, plasma and shock wave propagates in the nozzle absorbing microwave power. In this study, pressure histories in the thruster are measured using pressure gauges. Measured pressure history at the thruster wall shows constant pressure during plasma propagation in the nozzle. The result of measurement of the propagating velocities of shock wave and plasma shows that both propagate in the same velocity. These result shows that thrust producing model of analogy of pulse detonation engine is successful for the 1D thruster.
