摘要
为了准确确定迫击炮弹引信的解除保险距离性能指标，对迫击炮弹质心外弹道进行了大量计算，对比了迫击炮弹与加农炮、榴弹炮榴弹的威力特性，归纳了国外制式迫击炮弹引信的延期解除保险性能，分析了迫击炮弹的射击使用条件。国内已有制式引信的解除保险距离下限60m偏短，而对所有发射装药条件均要求200m的可靠解除保险距离也偏短，并且无必要。迫击炮弹引信解除保险距离下限一般应不低于100m，上限以0号发射装药平射考核时一般应不大于350m，而其它发射装药条件则不必再要求和考核。相应的解除保险时间一般可确定为2～5s。
In order to accurately determine the performance index of the mortar shell fuze arming distance, the mass center exterior ballistics of mortar shell is computed, the power characteristics of mortar shell and rifledbore gun shell are contrasted,the delay arming performance of foreign standard mortar shell fuze is concluded, the firing operation conditions of mortar shell are analyzed. The lower limits of arming distance of domestic service fuzes normally are about 60 m and shorter. And it is not only shorter distance for the reliable arming distance of 200 m required by all propellant charge conditions but also not necessary. The lower limit of arming distance of mortar shell fuze should normally not be less than 100 m, the upper limit should generally not be more than 350 m while examining with the No. 0 propellant charge under the condition of flat firing, and other propellant charge conditions needn＇t be required and used to examine again. The corresponding arming time can generally be confirmed as 2-5 s.
