摘要
在多管火箭弹发射的过程中,由于某些需要,要在战斗部头部放置一些其它部件。发射过程中由于发射时火箭弹所喷射出来的火焰对战斗部头部加热使其温度升高,如果温度过高就会毁伤部件,使其功能失效。因此为了防止部件的失效,必须研究发射过程中战斗部的温升情况。文中利用有限差分的方法根据某火箭弹发射的实际情况进行分析计算,得出了不同壁厚的战斗部壳体在发射过程中的温度变化情况,为以后有关战斗部头部温度的计算打下了基础。
During the multibaarrel rocket-powered missile ejection process,some other appliances are laid on the warhead's head for some needs,whose temperature often rises for the heating of the rocket-powered engine's flame, if the temperature is very high,the appliances will be destroyed and whose effects will be invalid.So the temperature rising situation is to be diescussed for avoiding the invalidation of the appliances.This paper gains different thickness warhead shells' temperature varieties conditions during the ejection process through adopting finite difference to analyze some actual situations,and this builds up the foundations for the posterior warhead's head temperature calculations.
