摘要
以超音速巡航弹气动加热环境为应用背景,针对导弹整流罩分离用爆炸螺栓的热学响应特性问题,开展爆炸螺栓的热学性能模拟仿真和试验研究,分析爆炸螺栓在气动加热过程的温度分布规律,并对比分析仿真计算与试验结果。研究表明:玻璃钢是一种很好的绝热材料,采用玻璃钢和隔热套等隔热结构的爆炸螺栓在气动加热环境中热安全性能良好,其内部的火工药剂装药几乎不会出现由气动热带来的意外发火问题。
Based on the application background of aerodynamic heating environment for supersonic cruise missile,aiming at the thermal response characteristics of the explosive bolts for missile fairing separation,the simulation and test study on the thermal performance of the explosive bolts were carried out,the temperature distribution law of the explosive bolts in the aerodynamic heating process was analyzed,and the simulation results and test results were compared and analyzed.The study show that FRP is a good thermal insulation material,the explosive bolts with FRP and thermal insulation jackets have good thermal safety performance in the aerodynamic heating environment,and the internal pyrotechnic composition is almost never accidentally triggered by pneumatic heating.
