| 摘 要： | 根据超高射频武器发射的基本原理,提出了一种可以解决火药燃气密封和弹丸药柱强度问题具有纵向尺寸小的新型装药结构--串联预装填系统,以此为基础根据经典内弹道学建立了内弹道数学模型,运用Matlab7.1语言编程,对内弹道过程进行了数值仿真,分析了射击频率的变化对内弹道性能的影响规律:非耦合时主要是由于各发弹在枪管中的物理位置不同而导致最大膛压和弹丸出枪口点速度有所变化,弱耦合时是由于弹前阻力对内弹道性能起主要作用而导致最大膛压和弹丸出枪口点速度有较大的变化.

| Abstract: | One new-style powder-installed structure of small fore-and-aft dimension,namely series-wound beforehand loading system,was brought forward according as projecting basic principle of hyper firing-rate weapon.The system could solve the problem of pressurization of powder burning gas and cylindrical powder intensity of bullet.On the basis of that,a mathematical model of interior ballistic was established by the classical interior ballistic theory,the process of interior ballistic was numerically simulated by M... |
