为了满足某先进战术导弹的更高要求 ,对该型号导弹原有固体火箭发动机的药型进行了改进 ,利用较先进的内孔开槽型药柱来代替原有药柱 ,并利用 GAD99软件对该药型的燃面变化规律进行研究 ,同时将所得的计算结果与相同尺寸的异型药柱进行比较 ,找出较优的药型
In order to meet the higher requirements of an advanced tactical missile, the drug type of the original solid rocket motor of this type of missile was improved. The more advanced slotted type drug column was used to replace the original drug column, and the GAD99 software was used The change of burning pattern of the drug type was studied, at the same time, the calculated results were compared with those of the same type of shaped drug column to find out the better drug type
