液体火箭爆炸碎片抛射的Monte-Carlo分析

Monte-Carlo analysis of the Projectile Fragments from Liquid Propellant Rocket Explosion Accident

根据动力学原理,推导了爆炸碎片在三维空间内的轨迹方程。以美国宇航局PYRO项目62号试验为例,利用Monte-Carlo方法模拟出碎片的轨迹曲线,统计计算得出碎片抛射距离的概率分布,并与试验数据进行了对比,结果具有良好的一致性,表明了该方法的可用性。研究结果对控制爆炸碎片风险,提高发射场区安全性和发射场规划布局等提供了一定的指导和借鉴。

Based on the dynamic theory, a fragment trajectory equation in three-dimensional system was deduced. The present study took No. 62 test of PYRO program developed by NASA as an example, and the trajectory of fragment was simulated by Monte-Carlo method. The probability of distance distribution was determined and had a fine consistency with the test data. The paper provides a method which is of great significance for improving the safety of launching site, controlling of fragment risk and planning range dis- tribution.
