该研究简报介绍了用膨胀波管产生高超声速气流的实验结果。用压力传感器测量了激波管内的激波速度,用激光全息摄影拍摄了飞船返回舱模型吹风时的激波形状,证实了在膨胀波管中建立了可用的流动条件。
The study briefed the experimental results of the hypersonic airflow generated by an expander wave tube. The shock wave velocity in the shock tube was measured by the pressure sensor. The shock wave shape of the spacecraft capsule model was shot by laser holography. It was confirmed that the available flow conditions were established in the expansion wave tube.
