| 摘 要： | 应用Ｃ２激光点火器研究了丁羟推进剂中氧含量，等因素及激光点火热通量与点瞎迟时间之间的关系，研究结果表明，随着丁羟推进剂氧量，燃速以及点火热通量的增加，推进的点火延迟时间缩短。超细铝粉能明显改善了羟推进剂的激光点火性能，使点火延这时间缩短。

| Abstract: | The effect of the oxygen content, burning rates of HTPB propellants and the laser radiant flux on the ignition delay time was investigated experimentally with a CO 2 laser ignition apparatus. The results show that the ignition delay time is shortened along with the increase of the oxygen content, burning rate of HTPB propellant and the laser radiant flux. The addition of ultrafine aluminium powder (UFAl) can improve the ignition properties of HTPB propellants significantly and make ignition delay time shortened. |
