真实火箭射流冲击流场中激波结构的实验研究

EXPERIMENTAL STUDIES ON SHOCK WAVE STRUCTURES IN THE IMPINGEMENT OF THE REAL ROCKET JET

摘要: 本文采用一种有效的激光-莫瑞光栅干涉系统首次拍摄到真实火箭燃气射流冲击流场的激波结构.解决了长期以来无法拍摄到高温、高速、强火焰光的火箭射流流场图像的问题。利用这一系统,研究了射流冲击流场中激波结构的一些变化规律,发现了一些新的激波结构。较系统地研究了欠膨胀射流冲击各种锥体的激波形态。

Abstract: In this paper, the pictures of shock wave structures in the flow field of real rocket jet impingement were gotten by a very effective Laser-Moire interference system. So the problem of taking the picture of real rocket jet with high temperature, high velocity and strong flame was solved. Using this system, we studied jet impinging cone and found some new shock wave structures.
