摘要
以光电箔片干扰弹抛撒为背景,提出了活塞式抛撒结构,分析系统工作原理,对内弹道特性、计算方法进行了探讨,建立了大数量光电箔片装填下抛撒过程内弹道模型,并在此基础上进行了数值仿真.运用内弹道模型首次对大数量箔片在舱体内的运动作用过程进行了研究,得出了抛撒过程内弹道特性.所提出的活塞式抛撒结构,增强了抛撒作用的可控性;内弹道模型的建立及数值模拟,为特殊装填结构发射系统的理论计算提供了新的有效途径.
Aiming at jammer with foils,a new system with piston was introduced.The working process was analyzed;the interior ballistics and numerical method were proposed.The interior ballistic equations in dispersion process under a large amount of foils filling was built,on the basis of which,the numerical simulation was carried out.The movement and action of a mass of foils filling in carrier body were firstly studied by using the interior ballistic model.The characters of interior ballistics of this system were obtained.The proposed piston dispensing structure improves the dispensing controllability.The numerical method provides a new effective approach for especial launch system.
