摘要
本文介绍火箭燃气射流冲击场的实验研究方法和结果,采用大口径长程莫阿偏折仪获得了自由射流和射流冲击场的莫阿偏折图,定量得到马赫盘位置、边界、斜激波等近场结构值,并与风洞冷射流模拟和数值模拟结果进行比较。
This paper describes the experimental research method and results of real rocket exhausted jet impingement field. By using a large aperture and long path moire deflectometer,the moire deflectograms of a free jet and jet impingement field are obtained. The Mach plate,boundary and oblique shock wave are quantitatively given from the moire deflectograms,and are compared with the results of modeling in wind tunnel and computer numerical method.
