| 摘 要： | 为探讨氢氧爆轰驱动激波风洞中的高氢混合比氢氧混合气直接爆轰的点火方法，对射流点火管的点火能力进行实验研究发现，点火管长度是决定射流点火能力的关键因素，射流点火能力随点火管长度的增加而增强。点火管与爆轰管之间无隔膜，结构简单，操作方便。同时观察了点火管中增添孔板对射流点火能力的影响，发现障碍物对射流点火能力具有减弱作用。

| Abstract: | the experiments of Oxy-hydrogen direct initiation by meansof turbulent jet are made systematically. The results indicate that thelength of ignition tube is the dominating factor which determines theignition capability of turbulent jet, and that the ignition capability ofturbulence jet increases with the length of ignition tube.Because the ignitioncapability can meet the demand of gas detonation driver shock tunneland it doesn't need additional facility, the turbulent jet initiation method can be applied to large Oxy-hydrogen detonation driyer shock tunnel. At the same, time the influence of obstacles on the ignition capability is studied. It is found that the present of obstacles will make theignition capability of turbulent jet weak. |
