火工品引爆线路电流的计算和验证是运载火箭控制系统设计中的一项重要内容。首先介绍火工品引爆线路组成,其次建立火工品引爆线路电流计算等效模型,给出3种不同类型引爆线路电流的理论计算方法,之后给出小电流测试、模拟发火试验和正式发火试验3种试验验证方法。试验结果表明理论计算结果与试验值基本吻合。
The calculation and verification of the ignition current of the ignition product is an important part of the design of the control system of the launch vehicle. Firstly, the composition of the ignition coil of the explosive was introduced, and then the equivalent model of the current calculation of the ignition coil of the explosive was established. The theoretical calculation methods of the three different types of ignition current were given. Then the small current test, simulated fire test and formal ignition test Three kinds of experimental verification methods. The test results show that the theoretical calculation results are in good agreement with the experimental values.
