产品名称:ubhg84式训练手榴弹
type ubhg84 practice hand grenade
生产单位:奥地利阿杰斯机电配件有限公司
arges armaturen gmbh,at
现状:生产
用途:用于训练和演习
概 述
ubhg84式手榴弹的外形与尺寸均与hg84式手榴弹相同。爆炸时只发出声响，供部队训练使用。
结构特点
ubｈｇ８４式手榴弹由弹体和引信组件组成。弹体为铸铁件，上下两端开孔，上口可装入训练引信组件，下口用于排放引信爆炸产生的高压气体和声响。弹体外表包覆一层黑色高强度塑料，其上压有一条宽１２ｍｍ的蓝色色带作永久性识别标志。
引信组件与作战用引信相似，但用一烟火剂装药代替雷管，可产生很大的响声，能很真实地模拟作战手榴弹的爆炸声。
ubhg84式训练手榴弹的弹体非常结实。使用后再装上训练引信组件，可反复使用。
性能数据
弹径----60mm
全弹长----115ｍｍ
全弹质量----520g
延期时间----4s
