| 中文摘要: |
| 目的 促进激光点火技术在安全弹药领域的应用。方法 从激光点火器作用后承受高动态压力的需求出发，研究基于玻璃封接技术的激光点火器密封性能及其影响因素。确定采用箱式电阻炉对激光点火器壳体与透镜间进行玻璃密封的温度为430 ℃，保温时间为13～15 min。对不同始发装药、不同密封工艺的激光点火器透镜发火后，其表面光学膜层变化、与激光点火器相连接的光纤端面损伤程度进行分析，研究点火前后承受气压性能变化。结果 始发装药为BPN等点火类药剂时，激光点火器具有较高的动态密封性能，可稳定达到30 MPa下2 min不泄露；始发装药为BNCP等起爆类药剂时，随着装药量的增大，密封性能变差。结论 改善玻璃封接工艺有利于提高密封性，如封接长度变长，发火后耐压密封性会有所提升。 |

| Objective To promote the application of laser ignition technique in the field of safe ammunition. Methods The sealing property and influencing factors of laser initiated squib (LIS) based on glass-metal sealing were researched from demands of bearing high-dynamic pressure after the action of the laser initiated squib. A box-type resistance furnace was applied to seal the housing and lens of the laser initiated squib at 430 ℃ for 13-15 min. Comparison and analysis were conducted to the damage of the optical film for the lenses in the LID and the surface of the connected optical fiber to discuss the pressure bearing performance of laser initiated squib with different initial loading and sealing performance before and after ignition. Results Pressure tests for post-fire LISs were conducted, which revealed LISs with initial loading like BPN could withstand higher pressure (e.g. 30 MPa 2 min) than LISs with initial loading like BNCP. The sealing performance got worse with the increase of loading amount. Conclusion Improvement of the glass sealing technique is favorable for improving the airtightness, such as prolonging the sealing length and improving the pressure tightness after ignition. |
