摘　　要：在子母弹活塞式抛撒背景下,提出了带导向管的抛撒机构,分析单燃烧室和双燃烧室结构工作原理,对子母弹系统抛撒散布过程的计算方法进行探讨,建立抛撒过程内弹道方程组及子弹散布模型,并在此基础上进行了数值仿真。系统总结了子母弹活塞式抛撒特点及性质;将带有导向管的活塞式抛撒技术和母弹旋转融合在一起,增强了子弹空中散布效能;子弹弹道模型及仿真给出了子弹空中运动规律及散布规律。为抛撒过程的研究、抛撒机构的工程化设计和结构优化、空中抛撒散布效果分析提供理论参考。Under the condition of piston dispensing of cluster bomb,a new dispensing mechanism with guiding tube was proposed;the working principles of single and double combustion chambers were analyzed;the numerical method of dispensing and dispersing processes of cluster bomb was explored;the interior ballistic equations in dispensing process and the models of submunition dispersion were built;the numerical simulation was performed by the equations and the models mentioned above.The characteristics of piston dispensing of cluster bomb were summerized systematically;the dispersing efficiency of bomblets in the air was augmented by combining piston dispensing with guiding tube with rotation of cluster bomb;the moving and dispersing rules of bomblets in the air were given by the model and the simulation.The investigated results provide theoretical references for dispensing process research,structural engineering design,structural optimization and the submunition dispersion effect analysis.
