补充资料:M67式延时杀伤手榴弹
概述
m67式延时杀伤手榴弹是在m33式防御型手榴弹基础上改进而成的,与m33式不同之处是多了一个保险夹。目前,该弹作为美陆军标准手榴弹之一种,仍在装备使用,且主要用于防御作战时杀伤有生目标。
结构特点
m67式手榴弹由弹体和引信组成。球形弹体用钢材制成,内装b炸药。引信为m213式延期引信。引信保险机构上增加一保险夹,可防止保险销被意外拉出,从而避免事故的发生,保险夹呈s形,用弹簧钢丝制成,一端套在引信体上,另一端夹住保险杆。使用时,卸掉保险夹后才能拔出保险销。
球形弹体是爆炸型弹最理想的弹体形状,弹体爆炸后破片分布均匀。
性能数据
弹径----63.5mm
全弹长----89.7mm

弹体材料----钢
装药类型----b炸药
装药质量----180g
引信类型----m213式延期
延期时间----4~5s
有效杀伤半径----15m
投掷距离----40m
