介绍了液体运载火箭初始段爆炸碎片散布分析系统设计的主要思路,并对系统中的液体火箭爆炸当量确定、碎片初始速度和碎片气动参数等关键技术进行了分析。运用仿真分析的手段对液体运载火箭爆炸碎片进行散布分析研究,形成完整的、系统的计算分析方法。在此基础上建立爆炸碎片计算、分析及演示平台,为爆炸碎片散布分析提供有效的工具,针对液体运载火箭在初始段爆炸情况下爆炸碎片的散布进行了系统的研究。

The general idea of the system design of the dispersion of explosion fragments is introduced and the key technologies of the system such as the determination of the equivalent of the liquid rocket explosion, the original speed of the fragments and the aerodynamic calculation are also analyzed. The simulation method is used to analyze the dispersion of explosion fragments to form complete and systematical calculation methods. Based on the previous analysis, a platform is developed for calculation, analysis and demonstration, thus an effective analytical tool to analyze the dispersion of explosion fragments is obtained, and the dispersion of explosion fragments during the initial phase of liquid rocket flight is studied systematically.
