微波火箭是一种由毫米波束提供动力的推进系统。在这项研究中,使用170GHz高功率陀螺仪作为微波源。在具有强制呼吸系统的圆柱形推进器模型中测量压力历史,并根据在推力壁处测量的压力历史估计推力脉冲。结果,获得了推力脉冲对呼吸空气的部分填充率的依赖性。当部分填充率小于1时,说明气缸内的空气没有被新鲜空气完全置换,冲量随着脉冲数的增加而减小。基于脉冲爆震发动机模型的分析发动机循环模型的预测与测量结果非常吻合。
The Microwave Rocket is a propulsion system powered by a millimeter -wave beam. In this research, a 170GHz high power gyrotron was used as a microwave source. A pressure history was measured in a cyli ndrical thruster model with a forced breath system and thrust impulse was estimated from the measured pressure histories at the thrust wall. As a result, dependency of thrust impulse on the partial filling rate of breathed air was obtained. When the partia l filling rate is less than unity, that means the air in the cylinder was not fully replaced by fresh air , the impulse decreased with the pulse counts. The prediction by an analytical engine cycle model based on a Pulse Detonation Engine model showed a goo d agreement with the measurement .
