摘要
本文介绍了使用激波风洞观察相对实验室驻定的斜爆轰波的方法、实验装置和初步实验结果。实验主要利用高分子可燃固体主膜片与高焓气体在加速、减速和膨胀降温过程中的混合作用 ,采用高速摄影技术对高超声速流场中尖劈所形成的高温和燃烧发光区进行动态观测 ,得到波角明显大于斜激波的结果 。
This paper introduces the experimental method of observing an oblique detonation wave standing in a laboratory reference frame with a shock tunnel, the experimental setup and primary results. This method makes mainly use of the mixing in deceleration and acceleration processes between solid macromolecule diaphragm and high enthalpy air in a shock tunnel and the radiating of high temperature gas and combustion, and takes directly pictures of waves on a sharp wedge in hypersonic flow fieldsemploying a digital high speed camera. Comparing the results with the relative oblique shock waves,a stading oblique detonation wave has considerabely observed.
