| 摘 要： | 发现了燃烧驱动激波管中入射激波马赫数异常升高的起因. 实验显示爆轰驱动能力强于燃烧驱动, 从而推动爆轰驱动技术的发展. 采用卸爆管消除爆轰波反射高压以及双爆轰驱动段全部消除爆轰波后的Taylor稀疏波, 使反向和前向爆轰驱动模式具有实用价值. 反向爆轰驱动技术还成功用来延长激波风洞试验时间.

| Abstract: | The cause for abnormal increase of shock Mach number in a combustion driven shock tube had been discovered.The experimental results show that the capabilities of gaseous detonation driver are stronger than to combustion driver which bring about a great advance in detonation driving technique.Using a dumping section to eliminate the reflected high pressure of the detonation wave and utilizing double detonation driver to eliminate completely the Taylor wave following the detonation wave makes the backward and... |
